C# '；未经授权'；用C开发的.net Web服务出错#

请求失败，HTTP状态为401：未经授权。为什么?

TravelCodesTranslator ws = GetEncodeDecodeWS();

// Create and set up the credentials for XmlSelectWebService
 string UserName = "username";
 string Password = "pwd";
// Xml Select uses Basic Authentication
NetworkCredential credentials = new NetworkCredential(UserName, Password);
CredentialCache cc = new CredentialCache();
ws.PreAuthenticate = true;
ws.Credentials = credentials;

XmlElement response;

if (_requestType == "Encode")
{
    response = ws.Encode(request.DocumentElement); // got error of
                                                   // "The request failed
                                                   //  with HTTP status 401:
                                                   //  Unauthorized."
}
else
{
    response = ws.Decode(request.DocumentElement);
}

改变

ws.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;

提示：错误信息非常清楚。上面说你的证件不正确。然后我会检查用户名和密码是否正确。如果它们是正确的，那么我将查看它们是否正确分配给请求。

再次编辑您的问题以删除用户名和pwd。请不要在公共场所发布敏感数据。您确定pwd/用户名正确吗。如果是这样，请尝试添加域。

ws.Credentials = credentials
