It's not entirely clear what the goal is. If you are attempted to add a method to a class that doesn't have the method, you can use an extesion method. namespace Mike.ConsoleApp { public class Program { static void Main( string [] args) { #region this is ok Personal specifiedPersonal = new Personal(); Personal employee = new Personal(); employee.DoSth(); #endregion #region this would be error Assembly assmebly = typeof (Personal).GetTypeInfo().Assembly; Type dynamicType = assmebly.ExportedTypes.Where(x => x.Name == "Personal" ).FirstOrDefault(); Personal dynamicEmployee = new Personal(); dynamicEmployee.DoSth(); #endregion Console.ReadLine(); } } public class Personal { public string FirstName { get ; internal set ; } public string LastName { get ; internal set ; } } public static class EmployeeExtension { public static void DoSth( this Personal person) { Console.WriteLine( "Done !!!" ); ; } } }

You cant pass a variable. Because it always expects as a "type" like string or complex classes. These are generic behavior. You cant expect like that by making to assign a variable instead of type. Genriccollection T- Tends to type. Not for variable. Thank you.
