總結C#靜態挪用WCF接口的兩種辦法。本站提示廣大學習愛好者：（總結C#靜態挪用WCF接口的兩種辦法）文章只能為提供參考，不一定能成為您想要的結果。以下是總結C#靜態挪用WCF接口的兩種辦法正文

若何應用

1、第一種方法比擬簡略，並且也是年夜家愛好的，由於不須要任何設置裝備擺設文件便可處理，只需曉得辦事契約接口和辦事地址便可以挪用。

2、應用Invoke的方法，然則須要在挪用客戶端設置裝備擺設WCF，設置裝備擺設後在Invoke類裡封裝辦事契約接口便可。

客戶端挪用DEMO

//第一種方法
string url = "http://localhost:3000/DoubleService.svc";
IDoubleService proxy = WcfInvokeFactory.CreateServiceByUrl<IDoubleService>(url);
int result = proxy.Add(1, 3);
 
 
//第二種方法<br><br>int result1 = WCFInvoke.Invoke(t => t.Add(1, 3));<br><br>

第一種方法比擬罕見，第二種方法是我參考別的一個項目中的寫法，個中的有一些細節我還沒有弄明確，完成了這個功效後還須要再看看這部門代碼，再消化消化。以上就是這篇文章的全體內容，願望能給年夜家帶來必定的贊助，假如有疑問年夜家可以留言交換。
