(Presuming you mean how to copy a file's content to a memory stream)

If you are using framework 4:

var memoryStream = new MemoryStream();

using var fileStream = new FileStream(FilePath, FileMode.Open, FileAccess.Read);
fileStream.CopyTo(memoryStream);

Here are code to create file

byte[] data = System.Text.Encoding.ASCII.GetBytes("This is a sample string");
System.IO.MemoryStream ms = new System.IO.MemoryStream();
ms.Write(data, 0, data.Length);
ms.Close();
