【问题描述】：

尝试运行 WCF 服务会导致以下结果。我已经在引用的页面上尝试了与 netsh 相关的建议 http://msdn.microsoft.com/en-us/library/ms733768.aspx 并没有得到任何工作。请提供有关如何解决此问题的信息。

【参考方案1】：

两个选项（两个都可以）

1.使用netsh实用程序提供对端口的访问

netsh http添加urlacl url=http://+:8439/user=DOMAIN\UserName

2.需要管理员权限

以管理员身份运行（Visual Studio 或应用程序本身）

【讨论】：

我已经尝试了第一个。尝试是成功的，但没有解决问题。但是，当我尝试使用第二个时，我现在收到一条不同的异常消息 "A registration already exists for URI '127.0.0.1:8439/'."

使用netsh http delete urlacl url=http://+:8439 ...

我已经删除了，但是异常 *** A Registration already exists for URI** 仍然存在

执行“netsh http show urlacl”并检查是否已经有8439的条目

刚查了一下，好像没有以前注册过这个端口号
