Converting a number to binary

This is very annoying, a long time ago I needed to convert an integer to a binary value for uploading to a device. Worked it out good and gone. The sad thing is I now need to convert an integer to a binary value for something else. I really need to get this going




C#
String s = "05";
  int b = 0;

   StringBuilder binary = new StringBuilder();
   for (int j = 0; j <= binary.Length; j++ )
   {
       int val = b;
       for (int i = 0; i < 8; i++)
       {
           binary.Append((val & 128) == 0 ? 0 : 1);
           val <<= 1;
       }
       binary.Append(' ');
   }
 MessageBox.Show("'" + s + "' to binary: " + binary);

from that I want 5 to end up as 101, to get it to 00000101 I can append the zeros to the string.
If I run the code it locks up

Serial_Number.Form1.button3_Click
(object sender = {Text = Cannot evaluate expression because the code of the current method is optimized.},
System.EventArgs e = {X = 46 Y = 6 Button = Left}) Line 77 + 0x40 bytes C#

and the debugger returns what am I doing wrong, I am starting to think I need a much deeper route through my system for the code.

  2. Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.
  3. If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Insults are not welcome.
  4. Don't tell someone to read the manual. Chances are they have and don't get it. Provide an answer or move on to the next question.
