MediaElement.MediaFailed event

Occurs when there is an error associated with the media Source.

Syntax


public event ExceptionRoutedEventHandler MediaFailed


<MediaElement MediaFailed="eventhandler" .../>

Event information

Delegate ExceptionRoutedEventHandler

Remarks

It is a best practice to always handle the MediaFailed event and take appropriate action.

Examples

The following code creates a MediaFailed event handler that calls a helper function to retrieve the HRESULT from the event arguments.


private void videoMediaElement_MediaFailed(object sender, ExceptionRoutedEventArgs e)
{
    // get HRESULT from event args 
    string hr = GetHresultFromErrorMessage(e);

    // Handle media failed event appropriately 
}

private string GetHresultFromErrorMessage(ExceptionRoutedEventArgs e)
{
    String hr = String.Empty;
    String token = "HRESULT - ";
    const int hrLength = 10;     // eg "0xFFFFFFFF"

    int tokenPos = e.ErrorMessage.IndexOf(token, StringComparison.Ordinal);
    if (tokenPos != -1)
    {
        hr = e.ErrorMessage.Substring(tokenPos + token.Length, hrLength);
    }

    return hr;
}
