public class Example()
{
    private readonly IDataValidator dataValidator = new DataValidator();;

    public void Method()

        var user = new User
        {
            Id = null,
            Name = "1234567890a",

        bool isValid = dataValidator.TryValidateResults(user, out List<ValidationResult> validationResults);

        // isValid: false

        // validationResult[0]
        //   ErrorMessage: "The Id field is required."
        // validationResult[1]
        //   ErrorMessage: "The field Name must be a string with a maximum length of 10."
        // validationResult[2]
        //   .ErrorMessage: "The field Age must be between 0 and 200."

Localization

Validation error messages can be localized.
You need to prepare resource files (.resx), ValidationAttribute and DisplayAttribute.
