    "Html": "<p>Your code looks a little confused.&nbsp;</p>\r\n<p>From what I see, your code does this: 1. Write some data to a stream. &nbsp;2. Seek in that stream to the beginning. &nbsp;3. Open a zip file. 4. Add an entry to the zip file, specifying the stream from step 1. &nbsp;5. Save the zip file to the same stream. ???</p>\r\n<p>The problem is step 5. &nbsp;You are overwriting the source stream. &nbsp;If you want to create a memory stream that contains a zip file, then create a NEW memoryStream that receives the zip content. &nbsp;Any entries added to the zipfile should use unique streams.&nbsp;</p>\r\n<p>Good luck.&nbsp;</p>\r\n<p>&nbsp;</p>",
