DownloadStringCompletedEventArgs Class

Note: This class is new in the .NET Framework version 2.0.

Provides data for the DownloadStringCompleted event.

Namespace: System.Net
Assembly: System (in system.dll)

public class DownloadStringCompletedEventArgs : AsyncCompletedEventArgs
public class DownloadStringCompletedEventArgs extends AsyncCompletedEventArgs
public class DownloadStringCompletedEventArgs extends AsyncCompletedEventArgs

Instances of this class are passed to the DownloadStringCompletedEventHandler.

The following code example demonstrates downloading a string asynchronously.

// Sample call : DownloadStringInBackground2 ("http://www.contoso.com/GameScores.html");
public static void DownloadStringInBackground2 (string address)
{
    WebClient client = new WebClient ();
    Uri uri = new Uri(address);

    // Specify that the DownloadStringCallback2 method gets called
    // when the download completes.
    client.DownloadStringCompleted += new DownloadStringCompletedEventHandler (DownloadStringCallback2);
    client.DownloadStringAsync (uri);
}


The following method is called when the download completes.

public static void DownloadStringCallback2 (Object sender, DownloadStringCompletedEventArgs e)
{
    // If the request was not canceled and did not throw
    // an exception, display the resource.
    if (!e.Cancelled && e.Error == null)
    {
        string textString = (string)e.Result;

        Console.WriteLine (textString);
    }
}
