Check Against Database

[ancgate]

The best way I found so far is to create extension method. But if you can add a feature as a I mentioned before to the Library, it would be a plus.

@ancgate Thank your for your suggestion. Show your clarification sample code please. ( Forgive my poor English.)

HI Allen, sorry for the late answer. This is my workaround. If you have more questions, feel free to contact me

public static class DatabaseExtension {

public static DataServiceProvider = new DataServiceProvider();

public static string GetUsername(this Person value)

 var a = DataServiceProvider.GetUsername(value);
 
 if (a!=null) {
 
    return value;
 }
 return

}

public class Person : IValidationDefinition
{
private const string username = "username already Exist";
private const string emptyUsername = "The Username should not be empty";
private const string password = "The password should match";
private const string regex = "XXXXXXXXXXXX";

    public void Define(Engine rules)
    {
        rules.For<Person>()
            .Setup(p => p.Username).MustNotEqual(p => p.Username.GetUsername()).WithMessage(username)
            .Setup(p => p.Password).MustMatchRegex(regex).WithMessage(password);
    }
}

I will be using the extensions method so far.
