示例

下面的代码示例显示此属性的值。

if ( sp->Certificate == nullptr )
   Console::WriteLine( "Certificate = (null)" );
else
   Console::WriteLine( "Certificate = {0}", sp->Certificate );

if ( sp->ClientCertificate == nullptr )
   Console::WriteLine( "Client Certificate = (null)" );
else
   Console::WriteLine( "Client Certificate = {0}", sp->ClientCertificate );

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)")
Else
    Console.WriteLine(("ClientCertificate = " + sp.ClientCertificate.ToString()))
End If

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

注解

谨慎

WebRequest、HttpWebRequest、ServicePoint和 WebClient 已过时，不应将其用于新开发。 请改用 HttpClient。

HTTP 协议版本为 HTTP/1.0 和 HTTP/1.1。
