    postheadericon Download file in a mobile C# application

    I didn't find a tutorial on how to download something on a mobile device in c#, most of the tutorials work with the WebClient class, but that's not in the compact framework mobile apps use. So I found this nice app that came close to what I needed and I took several other parts of code and fused this little example.


    //initiate the buffer size (I just took this value from a tutorial and it was large enough for my need
    int BufferSize = 32768;

    //create a HTTP request of your file and capture the response

               HttpWebRequest request = (HttpWebRequest)WebRequest.Create("");
               HttpWebResponse response = (HttpWebResponse)request.GetResponse();
               Stream readStream = response.GetResponseStream();

    //create a buffer

               byte[] ByteBucket = new byte[BufferSize + 1];

    //create a filestream to write the local file
              FileStream fileToWrite = new FileStream("", FileMode.Create, FileAccess.Write);
    //create a loop to read the downstream in parts and write each part to the wanted file
               bool done = false;
               int currentBytesRead = 0;
               int totalBytesRead = 0;
               while (done == false)
                    currentBytesRead = readStream.Read(ByteBucket, 0, BufferSize);
                    fileToWrite.Write(ByteBucket, 0, currentBytesRead);
                    totalBytesRead += currentBytesRead;
                    if (totalBytesRead == response.ContentLength) {
                        done = true;


    This was succesfully tested on a Windows CE 5 device.
