How to call dll file from c#?

1. Create a new solution

We have dll file of path
String path = String.Empty;
We have class name
String className = String.Empty;
Declare a Handler
System.Runtime.Remoting.ObjectHandle Handler;
Set path
path = Application.StartupPath + "\\" + "WindowsFormsApplication1" + ".DLL";
Set class name
className = "WindowsFormsApplication1.Form1";
Create instance
Handler = Activator.CreateInstanceFrom(path, className);
Declare a dynamic
dynamic task = Handler.Unwrap();
Call Form
((Form)task).Show();

Ok Thanks you!!!
