Example

Validation object

Validation is a object with properties(Message, IsValid).

var validationSuccess = Validation.Success("Successful message");

validationSuccess.Message; // "Successful message"
validationSuccess.IsValid; // true

var validationError = Validation.Error("Error message");

validationError.Message; // "Error message"
validationError.IsValid; // false

Validate request data

public Validation[] ValidateCreateUserRequest(CreateUserRequest request)
{
    IValidate validate;

    return new Validation[]
    {
        validate.IfNotNull(request.Name,"Name must not be null"),
        validate.IfNotZero(request.Age,"Age must not be 0")
    };
}

Throw if request data is invalid

public bool ValidateCreateUserRequest(CreateUserRequest request)
{
    IThrower thrower;
    thrower.IfNull(request.Name,"Name must not be null");
    thrower.IfZero(request.Age,"Age must not be 0");

    return true;
}

    Validation IfNull(object? obj, string message);
    Validation IfEqual(object obj, object objToComapere, string message);
    Validation IfNotZero(int number, string message);
    Validation IfNotZero(decimal number, string message);
    Validation IfGreaterOrEqual(int number, int numberToCompare, string message);
    Validation IfGreater(int number, int numberToCompare, string message);
    Validation IfGreaterOrEqual(decimal number, decimal numberToCompare, string message);
    Validation IfGreater(decimal number, decimal numberToCompare, string message);
    Validation IfNotEmpty(string text, string message);
    Validation IfParseToLong(string text, string message);
    Validation IfNotEmpty<T>(IEnumerable<T> list, string message);
    Validation IfOlder(DateTime date, DateTime dateToCompare, string message);
    Validation IfOlderOrEqual(DateTime date, DateTime dateToCompare, string message);
}

Throw Exception

public interface IThrower
{
    bool IfDefault<T>(T obj, string message);
    bool IfNotNull(object? obj, string message);

    bool IfNotEqual(object obj, object objToComapere, string message);
    bool IfZero(int number, string message);
    bool IfZero(decimal number, string message);
    bool IfGreaterOrEqual(int number, int numberToCompare, string message);
    bool IfGreater(int number, int numberToCompare, string message);
    bool IfGreaterOrEqual(decimal number, decimal numberToCompare, string message);
    bool IfGreater(decimal number, decimal numberToCompare, string message);
    bool IfEmpty(string text, string message);
    bool IfNotParseToLong(string text, string message);
    bool IfEmpty<T>(IEnumerable<T> list, string message);
    bool IfOlder(DateTime date, DateTime dateToCompare, string message);
    bool IfOlderOrEqual(DateTime date, DateTime dateToCompare, string message);
}
