Check Validators (.NET)
Author: Ryan Kueter
Updated: September, 2023
About
Check Validators is a free .NET library, available from the NuGet Package Manager, that provides the most flexible, simple, and powerful way to validate and guard your data. It provides a variety of user-defined validators that allow you to use LINQ to validate your data, in addition to hundreds of built-in validators. And it allows you to write your own custom validators and use them in your project without modifying this library.
Targets:
- .NET 6, .NET 7
Introduction
Each "Check" contains validation rules that can be chained together using method extension syntax (builder pattern).
// Validating a date
try
{
DateTime datetime = DateTime.Now;
new Check<DateTime>(datetime)
.IfNull()
.IfDefault()
.IfNotUtcTime()
.IfNot(date => date == DateTime.Now.AddDays(-1), "The date was not yesterday!")
.ThrowErrors();
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
Output:
Errors: 1) The datetime format is not Utc, 2) The date was not yesterday!.
Or you can add the filename, line number, and parameter by using ThrowErrors(true):
Errors: 1) The datetime format is not Utc, 2) The date was not yesterday!, in Program.cs:line 48. (Parameter 'datetime <DateTime>')
A Realistic Example
One of the more powerful features of this library is the ability to use LINQ to validate custom datatypes and include other check validators inside those validation rules. This can allow you to apply validators to collections.
Notice that the following checks are being used inside of user-defined validation rules.
- Check<string>(request.Email).IfNotEmail()
- Check<DateTime>(request.TimeStamp).IfNull().IfDefault().IfNotUtcTime()
- Check<string>(request.User).IfNotMatches("^letterstomatch", System.Text.RegularExpressions.RegexOptions.None)
//Validating a service request
var request = new MyServiceRequest();
var mycheck = new Check<MyServiceRequest>(request)
.IfNull()
.If(request => request.Email == null,
"The email address was null")
.AndIf(request => new Check<string>(request.Email).IfNotEmail().HasErrors(),
"The email address was not valid")
.If(request => request.TimeStamp == default,
"The timestamp was not set")
.AndIf(request => new Check<DateTime>(request.TimeStamp).IfNull().IfDefault().IfNotUtcTime().HasErrors(),
"An error occured with the timestamp")
.If(request => request.Id == 0,
"The requested id was 0")
.If(request => request.People is null || request.People.Count == 0,
"No people are in the list of people")
.AndIf(request => request.People.Where(person => new Check<string>(person.Email).IfNull().IfNotEmail().HasErrors()).Any(),
"A person in the list of people did not have a valid email address")
.AndIfNot(p => p.People.Where(x => x.Id > 0).Any(),
"You have an invalid person in your list of people.")
.If(request => new Check<string>(request.Email).IfEquals("adam@eden.eternal", StringComparison.InvariantCulture).HasErrors(),
"The email address was set to 'adam@eden.eternal'")
.If(request => new Check<string>(request.User).IfNotMatches("^rya", System.Text.RegularExpressions.RegexOptions.IgnoreCase).HasErrors(),
"The username does not begin with 'rya'")
.IfNot(request => request.Count > 20 && request.Count < 300,
"The count was not in the specified range")
.ReturnErrors(true);
Output:
Errors: 1) The email address was null, 2) The timestamp was not set, 3) A person in the list of people did not have a valid email address, 4) The count was not in the specified range, in Program.cs:line 63.
Providing a meaningful error message is always a good idea. But you can also leave off the error and it will include the validation expression as the error:
var request = new MyServiceRequest();
var mycheck = new Check<MyServiceRequest>(request)
.IfNull()
.If(request => request.Email == null)
.ReturnErrors(true);
Output:
Errors: 1) If(request => request.Email == null), in Program.cs:line 89.
User-Defined Validation Rules
User-defined validation rules allow you to use LINQ to validate your data. When writing user-defined validation rules, you typically want to write your own error message. If you don't, the expression that fails will be displayed in the error.
If and IfNot
If and IfNot conditions allow you to use LINQ to query objects and lists in the object. If the expression is false, it will produce an error message.
If(user => user.User is null)
If(user => user.User is null, "Custom error message.")
// Default Error: If({expression})
IfNot(user => user.User is null)
IfNot(user => user.User is null, "Custom error message.")
// Default Error: IfNot({expression})
AndIf and AndIfNot
AndIf and AndIfNot are similar to If and IfNot conditions, except that they only execute when the previous If or IfNot condition is valid. This provides better performance, and prevents unnecessary code execution and unnecessary errors. An example may include checking a child value of a value that was previously determined to be null. For example, if a list of people is null, you don't want to check that list for other validation errors because they will all fail. So, in that event, all of the following AndIf and AndIfNot statements are skipped. This can be reset by defining a new If or IfNot validation rule.
AndIf(user => user.User is null)
AndIf(user => user.User is null, "Custom error message.")
// Default Error: AndIf({expression})
AndIfNot(user => user.User is null)
AndIfNot(user => user.User is null, "Custom error message.")
// Default Error: AndIfNot({expression})
OrIf and OrIfNot
OrIf and OrIfNot are the opposite of AndIf and AndIfNot and only execute if a previous If rule fails validation. This can be reset by defining a new If or IfNot validation rule.
OrIf(user => user.User is null)
OrIf(user => user.User is null, "Custom error message.")
// Default Error: OrIf({expression})
OrIfNot(user => user.User is null)
OrIfNot(user => user.User is null, "Custom error message.")
// Default Error: OrIfNot({expression})
Utilities
Check validators comes with a number of utilities that can make validating data easier and more flexible. These utilities can be used inside of user-defined validation rules to create more powerful set of validations.
IsValid()
IsValid() returns a boolean value depending on whether all the rules passed validation. If they do, it will return true. If one failed, it will return false. This can be useful for validation scenarios where you don't want to throw an error.
using CheckValidators;
string? data = "Adam Smith";
var c = new Check<string>(data)
.IfNull()
.IfEmptyOrWhitespace()
.IfLengthEquals(10)
.IfNot(s => s.Contains("keyword"), "The string does not contain the keyword.")
.IsValid();
HasErrors()
If you want to determine if any validation errors occured, you could call HasErrors() to give you a boolean value.
GetErrors()
You can also retrieve each individual error for your own error handling.
// Getting errors
if (c.HasErrors())
{
foreach (var s in c.GetErrors())
{
Console.WriteLine(s);
}
}
ReturnErrors()
ReturnErrors() returns the errors as a string that would typically be thrown as an exception. If you want to include the the filename, line number, and parameter you can use ReturnErrors(true).
// Returning errors
if (!c.IsValid())
{
c.ReturnErrors(true);
}
The expression above will produce the following errors:
Errors: 1) String length should not equal 10 characters, 2) The string does not contain the keyword, in Program.cs:line 5. (Parameter 'data <String>')
ThrowErrors()
ThrowErrors() will throw all the errors in a formatted error message. If you want to include the the filename, line number, and parameter, you can use ThrowErrors(true).
// Throwing errors
if (!c.IsValid())
{
try
{
c.ThrowErrors(true);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
The expression above, for example, will throw the following errors:
Errors: 1) String length should not equal 10 characters, 2) The string does not contain the keyword, in Program.cs:line 5. (Parameter 'data <String>')
Extensibility
You can write your own custom extension methods anywhere in your project to write custom validators that are specific to your needs, similar to the following:
public static partial class CheckValidatorsExtensions
{
public static Check<List<T>?> IfEmpty<T>(this Check<List<T>?> data)
{
if (data.InvalidModel()) { return data; }
try
{
if (!data.Value.Any())
{
data.ThrowError("The list is empty.");
}
}
catch { }
return data;
}
}
Built-in Validations
Check validators also include a large number of built-in validation rules. Each of these rules has their own predefined errors that will provide the parameters you are supplying in the error messages.
General
If you want to throw an error when the object you are checking is null, then you need to include IfNull(). If the object you are checking is null, none of the other validations will be checked. So, this is a good one to include.

// Error: The value is null
IfNotNull()
// Error: The value is not null
String
IfNotEmail()
IfNotEmail(RegexPattern, System.Text.RegularExpressions.RegexOptions.None)
// Error: String '{value}' is not an email address
IfNotURL()
IfNotURL(RegexPattern, System.Text.RegularExpressions.RegexOptions.None)
// Error: String {value} is not a URL
IfNotValidPassword()
IfNotValidPassword(8, 2, 2, 2, 2)
IfNotValidPassword(MinLength, Uppercase, Lowercase, Numbers, SpecialCharacters)
// Possible errors:

A minimum of {numLower} lower-case characters.
A minimum of {numNumbers} numbers.
A minimum of {numSpecial} special characters.
