记录一下，方便下次使用，或者能帮助到别人。

一、添加服务引用，输入WSDL文件地址。

 

二、代码

 1 public TESTClient TestContext()
 2         {
 3             var binding = new BasicHttpBinding();
 4             binding.MaxReceivedMessageSize = int.MaxValue;
 5             binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;
 6             binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
 7             string Host = "webservice地址";
 8             var address = new EndpointAddress(Host);
 9             var method= new TESTClient (binding, address);
10             method.ClientCredentials.ServiceCertificate.Authentication.CertificateValidationMode = X509CertificateValidationMode.None;
11             method.ClientCredentials.UserName.UserName = "用户名";
12             method.ClientCredentials.UserName.Password = "密码";
13             return method;
14         }

三、调用

1 public string Test(string str)
2         {
3             var s = new TestService();
4             var result = s.TestContext().TestMethod(str);
5             return result;
6         }
