What is the difference? Stream

A FileStream is a Stream. All Streams only deal with byte[] data.

StreamReader is used to read data from the file. 

StreamWriter is used to write data into the file.

 Directly we are not write data into the file.First we should write into RAM & then through flush() it will be   written into the file.

StreamReader methods:

1)Read() : Reads single character.

2)ReadLine() : Reads single line.

3)ReadToEnd() : Reads full file.

For Example:

StreamReader str=new StreamReader(file1);

txtBox1.Text=str.ReadToEnd();

str.Close();

StreamWriter methods:

1)Write()

2)WriteLine()

For Example:

StreamWriter stw=new StreamWriter(file1);

stw.Write(txtBox1.Text);

stw.Flush();

stw.Close();
