Create a method to convert types from string to that type #15

Is there a need for a method that converts user types from string to that specific type?

If so, create an interface IGBaseObject that provides a method FromString() like this:

public interface IGBaseObject<T>
{
    public T FromString(string @string);
}

Another possibility would be to implement a static method FromString() that creates a new instance in every class that needs this:

public static T FromString(string @string)
{
    //Do stuff to be able to create a new T
    return new T();
}

Third we could add a constructor and/or a factory with only a string as parameter and create a new instance that way:

public T(string @string)
{
    //Do stuff to be able to create a new T
}

public interface ITFactory
{
    public IT Create(string @string);
}

Disadvantages of the last two solutions would be that a user would have to remember to implement these for every type, and you wouldn't be able to call it at a place where you don't have an instance of the actual type.
