Console::WriteLine( "ProtocolVersion = {0}", sp->ProtocolVersion->ToString() );
Console::WriteLine( "SupportsPipelining = {0}", sp->SupportsPipelining );

if (sp.Certificate == null)
    Console.WriteLine("Certificate = (null)");
else
    Console.WriteLine("Certificate = " + sp.Certificate.ToString());

if (sp.ClientCertificate == null)
    Console.WriteLine("ClientCertificate = (null)");
else
    Console. WriteLine("ClientCertificate = " + sp.ClientCertificate.ToString());

Console.WriteLine("ProtocolVersion = " + sp.ProtocolVersion.ToString());
Console.WriteLine("SupportsPipelining = " + sp.SupportsPipelining);

If sp.Certificate Is Nothing Then
    Console.WriteLine("Certificate = (null)")
Else
    Console.WriteLine(("Certificate = " + sp.Certificate.ToString()))
End If

If sp.ClientCertificate Is Nothing Then
    Console.WriteLine("ClientCertificate = (null)")

Remarks

Caution

WebRequest, HttpWebRequest, ServicePoint, and WebClient are obsolete, and you shouldn't use them for new development. Use HttpClient instead.

The HTTP protocol versions are HTTP/1.0 and HTTP/1.1.

Note

Since .NET 9, this property returns HttpWebRequest.ProtocolVersion.
