Examples

The following code example shows how to catch a certificate policy exception for a custom certificate policy. It assumes that the certificate policy object has been defined, that the Uniform Resource Identifier (URI) for the Web resource is contained in the variable myUri, and that there is a method named ProcessResponse that performs the work of the application.

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

Remarks

When the CertificatePolicy property is set to an ICertificatePolicy interface object, the ServicePointManager object uses the certificate policy defined in that instance instead of the default certificate policy.

The default certificate policy allows valid certificates and valid certificates that have expired.
