Method 1

Try

Image img = System.Drawing.Image.FromStream(myStream);

img.Save(System.IO.Path.GetTempPath() + "\myImage.Jpeg", ImageFormat.Jpeg);

Method 2

var tempFile = Path.GetTempFileName();
using (var fs = File.Create(tempFile))
{
   source.copyTo(fs);
}

where source is source stream. Now your source stream is saved at temp location (given by tempFile). Note that file name extension will be TMP.

Method 3

Your stream (image) is stream in the code below.

using (Stream output = new FileStream ("mycat.jpg"))
{
    byte[] buffer = new byte[32*1024];
    int read;

    while ( (read=stream.Read(buffer, 0, buffer.Length)) > 0)
    {
        output.Write(buffer, 0, read);
    }
}

Method 4

Have a look at the Bitmap Class. There’s a constructor overload that takes a Stream as parameter and there’s a method called Save which you can use to save it as a file.

Method 5

For windows phone 8.1 I found the following to work well. Create your TempStorageFile at whatever path you would like and then pass in your image’s stream like so:

var fileStream = await TempStorageFile.OpenAsync(Windows.Storage.FileAccessMode.ReadWrite);
            await RandomAccessStream.CopyAsync(imageStream, fileStream);
