[DOTNET] String Bug or somethig I missunderstood?

[Miguel �ngel Chac�n]

Just execute this lines of code and see the results. If you build a
string from a char array like this:
{'B','U','G',0,0,0,0}, the resulting string have a length of 8, and if
you build a new string adding some words to the first string and you
write it you�ll see 'blanks' for the '0' char, like this:
"BUG     NEW BUG". My expected result is that the length of the first
string to be 3 (no?) and when I add something the result should be
"BUGNEWBUG". Am I wrong? 

using System;
using System.IO;

namespace StringBugTest
{
        class Class1
        {
                [STAThread]
                static void Main(string[] args)
                {
                        byte[] bytes = new byte[8];     
                        bytes.SetValue((byte)66,0);
                        bytes.SetValue((byte)85,1);
                        bytes.SetValue((byte)71,2);
                        bytes.SetValue((byte)0,3);
                        bytes.SetValue((byte)0,4);
                        bytes.SetValue((byte)0,5);
                        bytes.SetValue((byte)0,6);
                        bytes.SetValue((byte)0,7);
                        MemoryStream ms=new MemoryStream(bytes);
                        BinaryReader bReader=new BinaryReader(ms);
                        char[] cadena=bReader.ReadChars(8);
                        string bug=new string(cadena);
                        Console.WriteLine(bug);
                        int a=bug.Length;
                        Console.WriteLine(a);
                        bug+="NEW BUG";
                        Console.WriteLine(bug);
                }
        }
}

Thanks for your attention.
