客戶端代碼：
WSHttpBinding bind = new WSHttpBinding();
EndpointIdentity identity = EndpointIdentity.CreateDnsIdentity("WCFTest");
Uri uri = new Uri("http://202.196.96.2:8888/Service1");
EndpointAddress address = new EndpointAddress(uri, identity);
//EndpointAddress address = new EndpointAddress("http://202.196.96.105:8888/Service1");
ChannelFactory<IService1> cf = new ChannelFactory<IService1>(bind, address);
cf.Credentials.UserName.UserName = "lr";
cf.Credentials.UserName.Password = "liuran123-";
IService1 iservice = cf.CreateChannel();
string str = iservice.GetData("測試成功！");
Console.Write(str);
Console.Read();
服務(wù)端服務(wù)能監(jiān)聽成功，但是在客戶端調(diào)用時會拋出這個異常信息：
Secure channel cannot be opened because security negotiation with the remote endpoint has failed. This may be due to absent or incorrectly specified EndpointIdentity in the EndpointAddress used to create the channel. Please verify the EndpointIdentity specified or implied by the EndpointAddress correctly identifies the remote endpoint
?
希望有遇到這個問題或者知道原因的幫忙看下吧，謝謝了，糾結(jié)了好多天了，就是沒找出問題！感激不盡！

原因找到了，我客戶端訪問的時候都用的是代碼加入的配置信息，但是少了message模式下客戶端驗(yàn)證類型：Username（自定義用戶名密碼），所以需要加上一句代碼
bind.Security.Message.ClientCredentialType = MessageCredentialType.UserName;
這樣就ok了，希望對有同樣錯誤的朋友有所幫助。當(dāng)然如果你客戶端訪問是不是用代碼加入的代碼信息，是在配置文件里就不會有這個問題。
