unable to access same MemoryStream multiple times, getting the MemoryStream closed on second attempt in C#?

Description:I am receiving a MemoryStream from a method and then I have to send it in email as attachment multiple times, i.e I have to utilise the same MemoryStream multiple time, it is working perfectly fine at first attempt but when I try to access it again it gives me error.
is there a way to store the MemoryStream separately for the purpose?
My current code looks like


     MemoryStream memoryStream = getMemoryStream();
     //following line works fine
     SendEmail(memoryStream);
     //but following line throws error
     SendEmail(memoryStream);

yes, you can create a copy of the MemoryStream and hold it in a new MemoryStream variable then you can use it for some other purpose as well. every time to want to utilise it you can create a new copy. For example you can use the following code chuck.

     MemoryStream memoryStreamActual = getMemoryStream();

     MemoryStream memoryStreamCopy= new MemoryStream();
     memoryStreamActual.CopyTo(memoryStreamCopy);

     memoryStreamActual.Position = 0;
     memoryStreamCopy.Position = 0;

     SendEmail(memoryStreamActual);
     SendEmail(memoryStreamCopy);
