I'm using the StorageFolder and need to check if a file exists befor I read it to avoid a exception.

my code looks like this:

StorageFolder storageFolder = ApplicationData.Current.LocalFolder;
StorageFile sampleFile = await storageFolder.GetFileAsync(myPath);

the problem is, I can't find a method which checks if a file exist

Last time I checked you had to catch an exception: (might have changed)

Edit: this is one way to do it :)

Like so:

    static async Task<bool> DoesFileExistAsync(string fileName)
    {
        try
        {
            await ApplicationData.Current.LocalFolder.GetFileAsync(fileName);
            return true;
        }
        catch
        {
            return false;
        }
    }
