You receive an unhandled exception error message when you use the MemoryStream class in the .NET Framework 1.1 Service Pack 1 (888226)

MORE INFORMATION

Steps to reproduce the behavior

1. Create a text file that is named Output.txt, and then paste the following code in Output.txt:

   <?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" 
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <soap:Body><HelloWorldResponse xmlns="http://tempuri.org/">
   <HelloWorldResult>SUCCESS:test</HelloWorldResult></HelloWorldResponse></soap:Body></soap:Envelope>

2. In Visual C# .NET, create a new Console Application project. By default, Class1.cs is created.
3. Paste the following code in the Class1.cs file:

   using System;
   using System.IO;
   using System.Text;
   using System.Xml;
   
   public class Form1
   {
   	static void Main() 
   	{
   		try
   		{
   
   			Stream _oldStream = new FileStream(@"Output.txt", FileMode.Open, FileAccess.Read);
   			Stream _newStream = new MemoryStream();
   
   			TextReader tr = new StreamReader(_oldStream);
   			TextWriter tw = new StreamWriter(_newStream);
   			tw.WriteLine(tr.ReadToEnd());
   			tw.Flush();
   
   			XmlReader reader = new XmlTextReader( new StreamReader( _newStream ) );
   			_newStream.Position = 0;
   			_newStream.Seek( 0, SeekOrigin.Begin );
   			reader.Read();
   
   			while( reader.Read() );
   
   			Console.WriteLine("Success");
   		}
   		catch (Exception ex)
   		{
   			System.Diagnostics.Debug.WriteLine(ex.ToString());
   			Console.WriteLine("Exception : " + ex.Message + "\n" + ex.StackTrace);
   		}
   	}
   }

4. Compile and then run the application.
