I have an ASP File upload, PostedFile.InputStream, it is giving us the System.IO.Stream. Is this file stream similar to that of getting 

System.IO.File.OpenRead("filename");

I have a Rackspace file content saver that gets the input as Stream, it's not getting the correct image displayed when used PostedFile.InputStream.

Normally PostedFile.InputStream and System.IO.Stream are same. So there is no need of any additional coding for Rackspace.

You can use file.InputStream as the Stream parameter to create the Object of Rackspace cloud files.

Another method which is not required but can test is 

byte[] buffer = new byte[file.InputStream.Length];
file.InputStream.Seek(0, SeekOrigin.Begin);
file.InputStream.Read(buffer, 0, Convert.ToInt32(file.InputStream.Length));
Stream stream2 = new MemoryStream(buffer);

You can use this stream also as input for creating object.
