在.net中访问远程服务时出错

Question

We are trying to access a java webservice through HTTPS from remote system in to our .net client system.we are facing an error:

This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server

Interesting thing is it is working in SOAP UI,but only problem with visual studio.Why it is working in soap UI rather not in Visual studio2010

protected void Page_Load(object sender, EventArgs e)
    {
        try
        {
            ServicePointManager.ServerCertificateValidationCallback += new System.Net.Security.RemoteCertificateValidationCallback(CertificationvAlidatefunction);
            mainclass.ClientCredentials.UserName.UserName = "testuser";
            mainclass.ClientCredentials.UserName.Password = "test123";


            response = mainclass.Testmethod(request);

        }
        catch (Exception ex)
        {
            Response.Write(ex.Message);
        }
    }
  private bool CertificationvAlidatefunction(object sender, System.Security.Cryptography.X509Certificates.X509Certificate certificate,
      System.Security.Cryptography.X509Certificates.X509Chain chain, SslPolicyErrors errors)
    {
        return true;

}

Answer 1

It is possible that the dotnet framework is related to the version of TLS supported. As far as I know,. Net4.0 is not compatible with tls1.2,you could refer to the following question for details.
Which versions of SSL/TLS does System.Net.WebRequest support?
Set up the configuration by using the following code snippets.

 ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls11;
            ServiceReference2.Service1Client client = new ServiceReference2.Service1Client();
            client.ClientCredentials.ServiceCertificate.SslCertificateAuthentication =
 new X509ServiceCertificateAuthentication()
 {
     CertificateValidationMode = X509CertificateValidationMode.None,
     RevocationMode = X509RevocationMode.NoCheck
 };

Feel free to let me know If there is anything I can help with.
