If you know what parameter you want to pass  take a Action lt T gt  for the type  Example   void LoopMethod  Action lt int gt  code  int count         for  int i   0  i  lt  count  i               code i              If you want the parameter to be passed to your method  make the method generic   void LoopMethod lt T gt   Action lt T gt  code  int count  T paramater         for  int i   0  i  lt  count  i               code paramater              And the caller code   Action lt string gt  s   Console WriteLine  LoopMethod s  10   Hello World        Update  Your code should look like   private void Include IList lt string gt  includes  Action lt string gt  action        if  includes    null                 foreach  var include in includes               action include            public void test         Action lt string gt  dg    s    gt             context Cars Include s              this Include includes  dg
