  • Question

  • Could you anyone offer a pointer to the document of System.IO.PathTooLongException for Windows Store app?

    Sorry for this dummy question, but I did do a lot online search and could not find it.

  • What is the scenario you are trying to solve? What is your actual goal here?

    You couldn't find it because it doesn't exist.

    If you search for PathTooLongException in the Visual Studio Object Browser when targetting a Windows Runtime solution you'll not get any hits.

    If you look at the documentation for System.IO.PathTooLongException you'll see that Windows Store apps are not included in the Version information.

  • Thanks for the response, Rob.

    The scenario is that a Windows Store app gets this exception, and I want to catch this exception, but have found System.IO.PathTooLongException cannot be resolved.  I am looking for the reference for this particular exception to gain more understanding including how to add the relevant reference so that I can use it in the app.

    In case you wonder how I know the app gets this exception, the app logs the exception including its type as following:

    Message: The filename or extension is too long.
    Type: System.IO.PathTooLongException 
    Stack Trace:   at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)
       at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)
       at System.Runtime.CompilerServices.TaskAwaiter.ValidateEnd(Task task)
       at MyApp.MainPage.<HandleFile>d__19.MoveNext()

  • Can you share an example which produces this error?

  • I have taken out the related code from the app and put it together as following:

        StorageFolder sf = await ApplicationData.Current.LocalFolder.CreateFolderAsync("Temp", CreationCollisionOption.ReplaceExisting);
        await sfFile.CopyAsync(sf);
    catch(Exception ex)
    where sfFile has the following:

    Path = "E:\\Temp\\aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaasdfffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffdddfffffffffffffffffffdddddddddddddddddddddddddddddddddddddddddd.png"
