In my application I have to save text file as well as binary files from a webserver by http protocol. Could somebody give me any hints how to proceed?
You could download the files and copy them to Isolated Storage.
Something like this...
private void DownloadFiles()
{
var wc = new WebClient();
wc.OpenReadCompleted += WcOpenReadCompleted;
wc.OpenReadAsync(new Uri("http://myserver/myfile.file", UriKind.Absolute));
}
public static void CopyStream(Stream input, Stream output)
{
var buffer = new byte[32768];
while (true)
{
int read = input.Read(buffer, 0, buffer.Length);
if (read <= 0)
return;
output.Write(buffer, 0, read);
}
}
private static void WcOpenReadCompleted(object sender, OpenReadCompletedEventArgs e)
{
using (IsolatedStorageFile userStoreForApplication = IsolatedStorageFile.GetUserStoreForApplication())
{
var isolatedStorageFileStream = userStoreForApplication.CreateFile("mylocalfilename");
using (isolatedStorageFileStream)
{
CopyStream(e.Result, isolatedStorageFileStream);
}
}
}
