Question

以下代码是webservice中的post方法。问题： NTML身份验证在.net framework 4.5中运行良好，但我想在.net framework 3.5中运行代码，使项目与windows xp兼容。

错误：401未经授权

try
            {
                System.Net.ServicePointManager.ServerCertificateValidationCallback = delegate(object sender2, System.Security.Cryptography.X509Certificates.X509Certificate certificate, System.Security.Cryptography.X509Certificates.X509Chain chain, System.Net.Security.SslPolicyErrors sslPolicyErrors)
                {
                    return true;
                };

                WebRequest request = WebRequest.Create("http://192.168.100.254"+urldata);
                request.Method = "POST";

                //NTML authentication
                CredentialCache cc = new CredentialCache();
                cc.Add(

                    new Uri("http://192.168.100.254"),
                    "NTLM",
                    new NetworkCredential("admin", "mnjkl"));
                request.Credentials = cc;


                byte[] byteArray = Encoding.UTF8.GetBytes(data);
                request.ContentType = "application/x-www-form-urlencoded";
                request.ContentLength = byteArray.Length;
                Stream dataStream = request.GetRequestStream();
                dataStream.Write(byteArray, 0, byteArray.Length);
                dataStream.Close();
                WebResponse response = request.GetResponse();

                dataStream = response.GetResponseStream();
                StreamReader reader = new StreamReader(dataStream);
                string responseFromServer = reader.ReadToEnd();
                reader.Close();
                dataStream.Close();
                response.Close();
                return responseFromServer;
            }
            catch (Exception Ex)
            {
                throw Ex;
            }

请任何知道.net3.5中NTLM身份验证的人帮助我。感谢。

我有同样的问题。我能够通过改变突出显示的本地组策略来解决它们您需要做的就是右键单击该策略并单击属性，您需要取消选中使用128位ssl Screenshot of the settings in local group policy

从.net4.5转换为.net3.5后，NTLM身份验证无法正常工作
