Dynamically create a class instance Using Reflection

 

Public   Interface Iwriter
{
VoidWrite ();
}

Public   Class Logwriter: iwriter
{
Public   Static   Int Typeid;


Iwriter members # Region Iwriter members

Public   Void Write ()
{
//Throw new exception ("the method or operation is not implemented .");
Console. writeline (typeid );
}

# Endregion
}

 

 

Assembly = Assembly. getexecutingassembly ();
Module [] modules = Assembly. getmodules ();
If (Modules ! =   Null )
{
Foreach (Module OBJ In Modules)
{
Type [] types = OBJ. gettypes ();
Foreach (Type objtype In Types)
{
If (Objtype. Name =   " Logwriter " )
{
Try
{
Objtype. invokemember ( " Typeid " , Bindingflags. setfield | Bindingflags. Public | Bindingflags. Static, Null , Null , New   Object [] {1200} );

Iwriter writer = (Iwriter) activator. createinstance (objtype, False );
Writer. Write ();
}
Catch (Exception ERR)
{
Console. writeline (ERR. Message );
}
}
}

}
}

Useful classes:

Assembly
Module
Type
Activator
System. Reflection namespace is essential before using these classes!
