Iphone – Stream video from the server . {iPhone SDK}

public static Stream GenerateStreamFromString(string s)
{
    var stream = new MemoryStream();
    var writer = new StreamWriter(stream);
    writer.Write(s);
    writer.Flush();
    stream.Position = 0;
    return stream;
}

Don't forget to use Using:

using (var stream = GenerateStreamFromString("a,b \n c,d"))
{
    // ... Do stuff to stream
}

About the StreamWriter not being disposed. StreamWriter is just a wrapper around the base stream, and doesn't use any resources that need to be disposed. The Dispose method will close the underlying Stream that StreamWriter is writing to. In this case that is the MemoryStream we want to return.

In .NET 4.5 there is now an overload for StreamWriter that keeps the underlying stream open after the writer is disposed of, but this code does the same thing and works with other versions of .NET too.

See Is there any way to close a StreamWriter without closing its BaseStream?

You should know that Android is quite strict regarding the video streams that you can stream. To be able to watch a stream a video (progressively watch and download) the video container must be correctly formatted.

There are many ways to create a container suitable for progressive streaming. You can look it up here: http://groups.google.com/group/android-beginners/browse_thread/thread/2a801ce5f71b5aaf?pli=1
