C# – Representing a C# Generic Method in a UML Class Diagram

cclass-diagramgenericsumlvisio

I have the following interface:

public interface IRegisterable
{
   T Register<T>(string username, string passw) where T : User, ICanLogin, new();
}

User is an abstract class, and ICanLogin is another interface.

Now, I want to represent the above interface with its method in a UML Class Diagram, in Visio.

How can I represent the above generic method with its constraints in a Class Diagram ?

A generic class is a Template class in UML see What is the correct way to represent template classes with UML?

So can't you use thye Parameterized Class in Visio http://etutorials.org/Programming/UML/Chapter+6.+Class+Diagrams+Advanced+Concepts/Parameterized+Class/

C# – Generic type conversion FROM string

I am not sure whether I understood your intentions correctly, but let's see if this one helps.

public class TypedProperty<T> : Property where T : IConvertible
{
    public T TypedValue
    {
        get { return (T)Convert.ChangeType(base.Value, typeof(T)); }
        set { base.Value = value.ToString();}
    }
}

C# – Create Generic method constraining T to an Enum

Since Enum Type implements IConvertible interface, a better implementation should be something like this:

public T GetEnumFromString<T>(string value) where T : struct, IConvertible
{
   if (!typeof(T).IsEnum) 
   {
      throw new ArgumentException("T must be an enumerated type");
   }

   //...
}

This will still permit passing of value types implementing IConvertible. The chances are rare though.
