ExpressValidator is a library that provides the ability to validate objects using the FluentValidation
library, but without object inheritance from AbstractValidator
.
Key Features
- Easy on-the-fly creation of object validator class called
ExpressValidator
by usingExpressValidatorBuilder
. - Possibility to dynamically change the parameters of the
FluentValidation
validators. - Supports adding a property or field for validation.
- Verifies that a property expression is a property and a field expression is a field, and throws
ArgumentException
if it is not. - Supports adding a
Func
that provides a value for validation. - Supports asynchronous validation.
- Targets .NET Standard 2.0+
Usage
//Class we want to validate
public class ObjToValidate
{
public int I { get; set; }
public string S { get; set; }
public string _sField;
public int PercentValue1 { get; set; }
public int PercentValue2 { get; set; }
}
var result = new ExpressValidatorBuilder<ObjToValidate>()
//Choose property to validate
.AddProperty(o => o.I)
//Usual FluentValidation rules here
.WithValidation(rbo => rbo.GreaterThan(0))
//Choose other property
.AddProperty(o => o.S)
//And set rules again
.WithValidation(rbo => rbo.MaximumLength(1))
//Choose field to validate
.AddField(o => o._sField)
//And set rules for the field
.WithValidation(rbo => rbo.MinimumLength(1))
//Add the Func that returns sum of percentage properties for validation
.AddFunc(o => o.PercentValue1 + o.PercentValue2, "percentSum")
//And set rules for the sum of percentages
.WithValidation(rbo => rbo.InclusiveBetween(0, 100))
//We get IExpressValidator<ObjToValidate> after calling the Build method
.Build()
//And finally validate the object
.Validate(new ObjToValidate() { I = i, S = s, PercentValue1 = pv1, PercentValue2 = pv2 });
if(!result.IsValid)
{
//As usual with validation result...
}
To dynamically change the parameters of the FluentValidation
validators:
- Create an options object that contains the parameters of validators.
- Configure the
ExpressValidatorBuilder<TObj, TOptions>
builder using the options object. - Pass the options to the builder's
Build
method. - Created
IExpressValidator<TObj>
validator will validate an aTObj
object using parameters from the options object.
To validate an object with different parameters, simply rebuild the validator using the same builder with the different options.
See example below.
//Object with options
var objToValidateOptions = new ObjToValidateOptions()
{
IGreaterThanValue = 0,
SMaximumLengthValue = 1,
SFieldMaximumLengthValue = 1,
PercentSumMinValue = 0,
PercentSumMaxValue = 100,
};
var builder = new ExpressValidatorBuilder<ObjToValidate, ObjToValidateOptions>()
.AddProperty(o => o.I)
//Get Greater Than validator parameter from options
.WithValidation((to, p) => p.GreaterThan(to.IGreaterThanValue))
.AddProperty(o => o.S)
//Get MaxLength validator parameter from options
.WithValidation((to, p)=> p.MaximumLength(to.SMaximumLengthValue))
.AddField(o => o._sField)
//Get MaxLength validator parameter from options for field
.WithValidation((to, f) => f.MaximumLength(to.SFieldMaximumLengthValue))
.AddFunc(o => o.PercentValue1 + o.PercentValue2, "percentSum")
//Get InclusiveBetween validator parameters from options
.WithValidation((to, f) => f.InclusiveBetween(to.PercentSumMinValue, to.PercentSumMaxValue));
//ValidationResult with parameters from objToValidateOptions
var result = builder
//Pass options in the Build method
.Build(objToValidateOptions)
.Validate(new ObjToValidate() { I = i, S = s, _sField = sf, PercentValue1 = pv1, PercentValue2 = pv2 });
if(!result.IsValid)
{
...
}
var objToValidateOptions2 = new ObjToValidateOptions() {...};
var result2 = builder
//Pass other options in the Build method
.Build(objToValidateOptions2)
.Validate(new ObjToValidate() { I = i, S = s, _sField = sf, PercentValue1 = pv1, PercentValue2 = pv2 });
//Check IsValid after rebuild
if(!result2.IsValid)
{
...
}
