The following example uses the ContentLength property to obtain the content length of the file system resource.

void GetPage( String^ url )
{
   try
   {
      Uri^ fileUrl = gcnew Uri( String::Concat( "file://", url ) );
      // Create a 'FileWebrequest' Object* with the specified Uri.
      FileWebRequest^ myFileWebRequest = (FileWebRequest^)( WebRequest::Create( fileUrl ) );
      // Send the 'fileWebRequest' and wait for response.
      FileWebResponse^ myFileWebResponse = (FileWebResponse^)( myFileWebRequest->GetResponse() );
      // Print the ContentLength and ContentType properties received as headers in the response Object*.
      Console::WriteLine( "\nContent length : {0}, Content Type : {1}", myFileWebResponse->ContentLength, myFileWebResponse->ContentType );
      // Release resources of response Object*.
      myFileWebResponse->Close();
   }
   catch ( WebException^ e ) 
   {
      Console::WriteLine( "\r\nWebException thrown.The Reason for failure is : {0}", e->Status );
   }
   catch ( Exception^ e ) 
   {
      Console::WriteLine( "\nThe following Exception was raised : {0}", e->Message );
   }
}
void GetPage(String* url) {
   try {
      Uri* fileUrl = new Uri(String::Concat(S"file://", url));
      // Create a 'FileWebrequest' Object* with the specified Uri.
      FileWebRequest* myFileWebRequest = dynamic_cast<FileWebRequest*>(WebRequest::Create(fileUrl));
      // Send the 'fileWebRequest' and wait for response.
      FileWebResponse* myFileWebResponse = dynamic_cast<FileWebResponse*>(myFileWebRequest->GetResponse());
      // Print the ContentLength and ContentType properties received as headers in the response Object*.
      Console::WriteLine(S"\nContent length : {0}, Content Type : {1}", __box(myFileWebResponse->ContentLength), myFileWebResponse->ContentType);
      // Release resources of response Object*.
      myFileWebResponse->Close();
   } catch (WebException* e) {
      Console::WriteLine(S"\r\nWebException thrown.The Reason for failure is : {0}", __box( e->Status));
   } catch (Exception* e) {
      Console::WriteLine(S"\nThe following Exception was raised : {0}", e->Message);
   }
}
