Question

And i have one interface

 public  interface IMethod
 {
     String Add(string str);
     Boolean Update(string str);
     Boolean Delete(int id);
 }

I have declared another Interface Like this
which has IMethod as property.

public interface IFoo
{
     IMethod MethodCaller { get  ; set; }  
}

Now I gone implement IFoo interface in my one of class and from which i want to call IMethods method.

Class implementation

 public MyClass : IFoo
 { 
     public IMethod MethodCaller{ get  ; set; }  
 }

How do i do it ? how do i call Add Update Delete method from MyClass

MyClasses that implement IMethod as follows :

public class foo1:IMethod
{

         public String Add(string str){ return string.Empty;}

         Boolean Update(string str){//defination}

         Boolean Delete(int id){ //defination}
}

public class foo2:IMethod
{

         public String Add(string str){ return string.Empty;}

         Boolean Update(string str){//defination}

         Boolean Delete(int id){ //defination}
}

Inside a class:

public MyClass : IFoo   
{
   public void CallAllMethodsOfIIMethodImpl()
   {
       if (this.MethodCaller != null)
       {
          this.MethodCaller.Add( ... );
          this.MethodCaller.Delete( ... );
          this.MethodCaller.Update( ... );
       }
   }
}

Outside:

MyClass instance = new MyClass();
if (instance.MethodCaller != null)
{
   instance.MethodCaller.Add( ... );
   instance.MethodCaller.Delete( ... );
   instance.MethodCaller.Update( ... );
}
