Fluent validation

Hello Jubin,

I would appreciate if you could provide more insights on how you are expecting fluent validation dynamically set on model classes.

Hello Jobin,

Hope below code good for you.

var employee = new Employee
{

};

var result = Validate("FluentValidationDemo.Validator.EmployeeValidator", employee);
Console.WriteLine($"{nameof(Employee)} validation");
foreach (var item in result.Errors)
{
    Console.WriteLine(item.ErrorMessage);
}

Console.WriteLine();
Console.WriteLine($"{nameof(Student)} validation");
var student = new Student
{

};

result = Validate("FluentValidationDemo.Validator.StudentValidator", student);

foreach (var item in result.Errors)
{
    Console.WriteLine(item.ErrorMessage);
}

FluentValidation.Results.ValidationResult Validate(string typeName, object data)
{
    var type = Type.GetType(typeName);
    object? instance = null;
    if (type != null)
    {
        instance = Activator.CreateInstance(type);
    }

    var methods = type.GetMethods();
    var method = methods.FirstOrDefault(x => x.IsFinal && x.Name == "Validate");
    var response = method.Invoke(instance, [data]);
    var result = response as FluentValidation.Results.ValidationResult;
    ArgumentNullException.ThrowIfNull(result);

    return result;
}

Output

Thanks

Hello Jobin,

You need to use a reflection and try to create an object and invoke that method.

I used this in my one of the organisation.

var type = Type.GetType("Your class name space");
object? instance = null;
if (type != null)
{
    instance = Activator.CreateInstance(type, _loggerFactory);
}

return instance;

or 

instance.MethodName();

Try this way,
Hope it will help you.

Thanks

yes jaimin ,

request validate in dynamically ? any options here fluent validation?

Hello Jobin,

You mean to say based on the request, automatically identified the fluent validation class and validate that request.

This is my understanding correct?

Dynamically validation set in request model class options here in Fluent validation 

Hello Jobin,

Can you more elaborate your requirement so we are understand and give an idea.

Thanks
