Just look at the wrong place in the source code.

Using system;using system.collections.generic;using system.linq;using system.text;using System.IO;namespace Filestreamtest{class Program {static void Main (string[] args) {string file = @ "D:\temp.t            XT ";            FileStream FileStream;            if (file.exists (file)) {FileStream = File.openread (file);            } else {fileStream = File.create (File); }//Use of the StreamWriter is used here, which causes the flow of the FileStream to be closed using (StreamWriter writer=new StreamWriter (f) After the end of the domain Ilestream)) {writer.            WriteLine ("Test some plain text!");            }//The file stream that was passed in to FileStream has been closed, so it will run the Times wrong using (StreamReader reader=new StreamReader (FileStream)) {Console.WriteLine (reader).            ReadLine ());            } filestream.close ();        Filestream.dispose (); }    }}

The solution is to reuse the stream, instead of using a using block, or passing the file name to StreamWriter, StreamReader constructs, rather than the previous FileStream.
