DLL is dynamically loaded in. NET and released in time after the call.

Problem:

In many cases, we want to dynamically loadProgramTo release the loaded DLL file in time to release resources and update DLL files.

Solution:

Currently, CLR does not provide a method to uninstall an assembly. While assembly is resident in appdomain, appdomain can be dynamically detached and created.

For example, there is a dynamically generated Class Library:

Public   Class Helloworld: Export albyrefobject

{
Public Helloworld ()
{

}

Public   Void Task1 ( String S)
{
Console. writeline ("Task1" +S );
}
}

Dynamic call // File: invoke. CS

Using System;
Using System. reflection;
Using System. runtime. remoting;



Public   Class Invokemethod
{

Public   Static   Void Main (string [] argv)

{

Appdomainsetup info =   New Appdomainsetup ();
Info. applicationbase =   " File :/// "   + System. environment. currentdirectory;
Appdomain dom = Appdomain. createdomain ( " Remotedomain " , Null , Info );
Assembly ASM = Assembly. Load ( " Helloworld2 " );
Object OBJ = ASM. createinstance ( " Helloworld " );
Methodinfo minfo = ASM. GetType ( " Helloworld " ). Getmethod ( " Task1 " );
Minfo. Invoke (OBJ, New   String [] {"Task 1"} );
Appdomain. Unload (DOM );

}

}

Restrictions:
The DLL to be dynamically loaded must be in the same directory as the host.
