Unsure how to handle Invalid token 'int' in class, struct, or interface member declaration error

I am extremely new to C# and I get the following error with int highlighted at every line item:

Invalid token 'int' in class, struct, or interface member declaration

How do I fix the syntax below to work properly?
The following was taken from Sams Teach Yourself Microsoft Visual C#.NET 2003 in 24 hours on page 352.
Also - I hate the way my IDE in 2003 keeps trying to tab the braces once I press <ENTER> on a line item - it is not helping to much as I type in these examples.  Any suggestions is much appreciated - Stephen

using System;

namespace Class_Programming_Example
{
      /// <summary>
      /// Summary description for clsMyClass.
      /// </summary>
      public class clsMyClass
      {
      Private int m_intHeight;

      Public int Height
            {
                  get
                  {
                        return m_intHeight;
                  }
                  set
                  {  
                        m_intHeight = value;
                  }
            }
            public clsMyClass()
            {
            
                  //
                  // TODO: Add constructor logic here
                  //
            }
      }
}
