You can do this trick by finding the right methods through Reflection:

public static T To (object obj)
{
    Type sourceType = obj.GetType ();
    MethodInfo op = sourceType.GetMethods ()
                    .Where (m => m.ReturnType == typeof (T))
                    .Where (m => m.Name == "op_Implicit" || m.Name == "op_Explicit")
                    .FirstOrDefault();

    return (op != null)
        ? (T) op.Invoke (null, new [] { obj })
        : (T) Convert.ChangeType (obj, typeof (T));
}

In .NET 4.0, you can use dynamic keyword as suggested in other answers.
