关于验证ClientCredentials的问题，请大家帮帮忙，谢谢
我在做wp端引用webservice。
在wp端的请求代码是：
var client = new ServiceReference1.WS_LoginSoapClient();
client.ClientCredentials.UserName.UserName = "a";
client.ClientCredentials.UserName.Password = "b";
client.HelloWorldCompleted += client_HelloWorldCompleted;
client.HelloWorldAsync();
