Hi,
I am currently porting some (actually a lot of) code from .NET to Mono for
Android.
At one point there seems to be a problem with the WebClient class, in
particular when the connected server responds with an error. The following
code snippet can easily provoke (and also explains) the problem:
System.Net.WebClient aWebClient = new System.Net.WebClient();
aWebClient.DownloadStringCompleted += (sender, args) =>
{
// This logging output appears as expected
Android.Util.Log.Info("TADA", "DownloadStringCompleted");
// This also appears as expected. the property Error is non-null due to the
error
if (args.Error != null)
{
Android.Util.Log.Error("TADA", "Error");
}
// At the following line an exception is thrown just because the Result
property was accessed:
// System.Reflection.TargetInvocationException: Exception has been thrown by
the target of an invocation.
// Instead the Result property should be null.
if (args.Result != null)
{
Android.Util.Log.Info("TADA", args.Result);
}
};
aWebClient.DownloadStringAsync(new
Uri(@"https://justtogetanerror.com/doesnotexist";));
I am testing/debugging on a LG Optimus 2X and downloaded the latest Mono for
Android yesterday.
Thanks for your attention
Andreas
