What is a Stream Reader?
StreamReader is designed for character input in a particular encoding, whereas the Stream class is designed for byte input and output. Use StreamReader for reading lines of information from a standard text file. Important. This type implements the IDisposable interface.
Why use Stream Reader?
C# StreamReader is used to read characters to a stream in a specified encoding. StreamReader. Read method reads the next character or next set of characters from the input stream. StreamReader is inherited from TextReader that provides methods to read a character, block, line, or all content.

What is MemoryStream in C#?

Does MemoryStream need to be disposed?
MemoryStream does not have any unmanaged resources to dispose, so you don’t technically have to dispose of it. The effect of not disposing a MemoryStream is roughly the same thing as dropping a reference to a byte[] — the GC will clean both up the same way.
