c# - I want to convert all my classes in Generic classes then call classes methods -

i want use generics able use proxy kind of realclient.

public interface iclient {     string getdata(); }  public class realclient : iclient {     string data;     public realclient()     {         console.writeline("real client: initialized");         data = "success";     }      public string getdata()     {         return data;     } }   public class proxy : iclient {     realclient _classobject = new realclient();     public proxy()     {         console.writeline("proxyclient: initialized");     }      public string getdata()     {         return _classobject.getdata();     } }   class program {     static void main(string[] args)     {         proxy proxy = new proxy();         console.writeline("data proxy client = {0}", proxy.getdata());          console.readkey();     } } 

it seems you're trying implement proxy design pattern, , want proxy work kind of iclient.

if so, don't need generics this. you'd implement proxy:

public class proxy : iclient {     private readonly iclient _client;     public proxy(iclient client)     {         _client = client;         console.writeline("proxyclient: initialized");     }      public string getdata()     {         return _client.getdata();     } } 

keep simple.
