The MemoryStream creates a stream whose backing store is memory. Actually, it represents a pure, in-memory stream of data.
Memory is much faster when compared to disk or network accesses. With MemoryStream, you can act upon the byte stored in memory rather than a file or other resource. Use a byte because it is a fixed sized object making it easier for memory allocation and cleanup and holds relatively no overhead, especially since you don't need to use the functions of the MemoryStream.
This string is currently saved in the StreamWriters buffer. Flushing the stream will force the string whose backing store is memory MemoryStream. The StreamReader will read from the current position of the MemoryStream which is currently set at the end of the string earlier we just wrote to it.

Switch your project to iText 7 , integrating the latest developments. Check related iText 7 content! When I save stream to file, the resulting PDF is not correct. The file attachment will always be an XML file, which I need to create in memory and never will be in file system.
