I'm trying to allow my computer to send video files to my app (Windows Phone 8).

if file is large size receive memory exception.

how to solve?

this is my code

private async void HandleRequest(StreamSocket socket)
{
    //Initialize IO classes
    DataReader reader = new DataReader(socket.InputStream);
    reader.InputStreamOptions = InputStreamOptions.Partial;

    // read request
    var stringHeader = await reader.LoadAsync(4);

    if (stringHeader == 0)
    {
       // disconnected
       return;
    }

    // get length
    int length = reader.ReadInt32();

    // initiate data
    byte[] data = new byte[length];

    // load and read data
    uint bytes = await reader.LoadAsync((uint)length);
reader.ReadBytes(data);

}
