如果我想使用Windows身份验证，请使用：public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
ServiceReference1.Service1Client s1 = new ServiceReference1.Service1Client();
s1.ClientCredentials.UserName.UserName = "TestUser";
s1.ClientCredentials.UserName.Password = "TestPassword";
string str = s1.GetData(1);
}
}
如果您分别使用：ClientCredentials.UserName.UserName和ClientCredentials.UserName.Password提供用户名和密码，那么客户端是否始终与基本身份验证通信？
这个问题来自这个问题：Basic Authentication appears to have no security header。我很困惑，为什么我在Authorization标头中看不到基本的身份验证凭据。
我在这里阅读了文档，但我没有找到答案：https://msdn.microsoft.com/en-us/library/system.servicemodel.description.clientcredentials.username(v=vs.110).aspx。
