X509ChainElement.Information 属性

定义

命名空间:

System.Security.Cryptography.X509Certificates

程序集:

System.Security.Cryptography.dll

Source:

X509ChainElement.cs

从非托管证书链结构中获取其他错误信息。

public:
 property System::String ^ Information { System::String ^ get(); };

public string Information { get; }

member this.Information : string

Public ReadOnly Property Information As String

属性值

String

一个字符串，表示 Crypto API 中非托管 pwszExtendedErrorInfo 结构的 CERT_CHAIN_ELEMENT 成员。

示例

下面的代码示例打开当前用户的个人证书存储，允许用户选择证书，然后将证书和证书链信息写入控制台。 输出取决于用户选择的证书。

//Output chain element information.
Console::WriteLine( "Chain Element Information" );
Console::WriteLine( "Number of chain elements: {0}", ch->ChainElements->Count );
Console::WriteLine( "Chain elements synchronized? {0} {1}", ch->ChainElements->IsSynchronized, Environment::NewLine );
System::Collections::IEnumerator^ myEnum = ch->ChainElements->GetEnumerator();
while ( myEnum->MoveNext() )
{
   X509ChainElement ^ element = safe_cast<X509ChainElement ^>(myEnum->Current);
   Console::WriteLine( "Element issuer name: {0}", element->Certificate->Issuer );
   Console::WriteLine( "Element certificate valid until: {0}", element->Certificate->NotAfter );
   Console::WriteLine( "Element certificate is valid: {0}", element->Certificate->Verify() );
   Console::WriteLine( "Element error status length: {0}", element->ChainElementStatus->Length );
   Console::WriteLine( "Element information: {0}", element->Information );
   Console::WriteLine( "Number of element extensions: {0}{1}", element->Certificate->Extensions->Count, Environment::NewLine );
   if ( ch->ChainStatus->Length > 1 )
   {
      for ( int index = 0; index < element->ChainElementStatus->Length; index++ )
      {
         Console::WriteLine( element->ChainElementStatus[ index ].Status );
         Console::WriteLine( element->ChainElementStatus[ index ].StatusInformation );
      }

            }
        }
    }
    store.Close();

'Output chain element information.
Console.WriteLine("Chain Element Information")
Console.WriteLine("Number of chain elements: {0}", ch.ChainElements.Count)
Console.WriteLine("Chain elements synchronized? {0} {1}", ch.ChainElements.IsSynchronized, Environment.NewLine)

Dim element As X509ChainElement
For Each element In ch.ChainElements

        Dim index As Integer
        For index = 0 To element.ChainElementStatus.Length
            Console.WriteLine(element.ChainElementStatus(index).Status)
            Console.WriteLine(element.ChainElementStatus(index).StatusInformation)
        Next index
    End If
Next element
