c# – WCF功能返回后继续

我有一个Web应用程序通过WCF连接到 Windows服务并调用方法.在该方法返回其结果后(并且所有内容都成功 – 请参见下面的行**)我希望该服务继续并执行其他一些工作.

最简单的方法是什么？

谢谢

C#代码

//Add Files To Control Manager
    public ReturnClass FilesToControl(List<Item> lstNewItems,String Referencenumber,String Type,String Description)
   {
       try
       {
           String ThisisAnItemToControl = "";
           String ThisIsItsType = "";

           for (int i = 0; i < lstNewItems.Count; i++) // Loop through List with for
           {
               ThisisAnItemToControl = lstNewItems[i].Paramater;
               ThisIsItsType = lstNewItems[i].Type;

               // Do a pre @R_489_10943@k on the item

               // Does File Exist

               if (!File.Exists(ThisisAnItemToControl))
                   return new ReturnClass(-1,ThisisAnItemToControl + " does not exist",String.Empty,null,null);  



           }

           return new ReturnClass(1,"",null);


           // Now that we have returned a result to the web application we can get to work and modify the items under control but how can i do this?

         //  **??


       }

       catch (Exception eX)
       {

           return new ReturnClass(-1,ex.message.ToString(),null);

       }
