範例

下列程式碼範例示範如何攔截自訂憑證原則的憑證原則例外狀況。 它假設已定義憑證原則物件、Web 資源的統一資源識別元 (URI) 包含在 變數 myUri 中，而且有名為 ProcessResponse 的方法可執行應用程式的工作。

ServicePointManager::CertificatePolicy = gcnew MyCertificatePolicy;

// Create the request and receive the response
try
{
   WebRequest^ myRequest = WebRequest::Create( myUri );
   WebResponse^ myResponse = myRequest->GetResponse();
   ProcessResponse( myResponse );
   myResponse->Close();
}
// Catch any exceptions
catch ( WebException^ e ) 
{
   if ( e->Status == WebExceptionStatus::TrustFailure )
   {
      // Code for handling security certificate problems goes here.
   }
   // Other exception handling goes here
}

ServicePointManager.CertificatePolicy = new MyCertificatePolicy();

// Create the request and receive the response
try
{
    WebRequest myRequest = WebRequest.Create(myUri);
    WebResponse myResponse = myRequest.GetResponse();
    ProcessResponse(myResponse);
    myResponse.Close();
}
// Catch any exceptions
catch (WebException e)
{
    if (e.Status == WebExceptionStatus.TrustFailure)
    {
        // Code for handling security certificate problems goes here.
    }
    // Other exception handling goes here
}

ServicePointManager.CertificatePolicy = New MyCertificatePolicy()
       
' Create the request and receive the response
Try
    Dim myRequest As WebRequest = WebRequest.Create(myUri)
    Dim myResponse As WebResponse = myRequest.GetResponse()
    
    ProcessResponse(myResponse)

    myResponse.Close()
    
' Catch any exceptions
Catch e As WebException
    If e.Status = WebExceptionStatus.TrustFailure Then
        ' Code for handling security certificate problems goes here.
    End If
    ' Other exception handling goes here
 End Try

備註

CertificatePolicy當 屬性設定為 ICertificatePolicy 介面物件時， ServicePointManager 物件會使用該實例中定義的憑證原則，而不是預設憑證原則。

預設憑證原則允許有效的憑證和過期的有效憑證。
