displaying two strings of ascii conversion

Question

hello i am supposed to display the ascii character set from 32 to 100 and then from 225-250. I have found the code to show 32 to 100 but cannot think of how to put 225 to 250 in there as well. here is my code. I just need to add an additional string of the ascii character set from 225 to 250 underneath it.

using System;

namespace hexbox
{
   class Program
   {
      public static void Main(string[] args)
      {
        Console.Write(" Dec Char  Hex\n -------------\n");
        int min = 032;
        int max = 100;
         for ( int i = min; i < max; i++ )
         {
            // get ascii character
            char c = (char) i;

            // get display string
            string display = string.Empty;

            if (char.IsWhiteSpace(c))
            {
               display = c.ToString();
            }
            else if (char.IsControl(c))
            {
               display = "control";
            }
            else
            {
               display = c.ToString();
            }
            // write table row
            Console.Write(string.Format("{0: 000}{1, 3}{0, 6:X2}\n", i, display));
         }
      }// end Main
   }// end class
}// end namespace

Try something like this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace daniweb
{
  public static class DisplayPairs
  {
    private class IntegerPair
    {
      private int _min;
      private int _max;
      public int Min { get { return _min; } }
      public int Max { get { return _max; } }
      private IntegerPair() { }
      public IntegerPair(int Min, int Max)
        : this()
      {
        this._min = Min;
        this._max = Max;
      }
    }
    private static string GetDisplayString(char c)
    {
      if (char.IsWhiteSpace(c))
        return c.ToString();
      else if (char.IsControl(c))
        return "control";
      else
        return c.ToString();
    }

    public static void RunTheProgram()
    {
      //from 32 to 100 and then from 225-250
      List<IntegerPair> lst = new List<IntegerPair>();
      lst.Add(new IntegerPair(32, 100));
      lst.Add(new IntegerPair(225, 250));
      foreach (IntegerPair ip in lst)
      {
        for (int i = ip.Min; i <= ip.Max; i++)
        {
          char c = (char)i;
          string display = GetDisplayString(c);
          Console.Write(string.Format("{0: 000}{1, 3}{0, 6:X2}\n", i, display));
        }
      }
    }
  }
}

Calling it:

private void button3_Click(object sender, EventArgs e)
    {
      DisplayPairs.RunTheProgram();
    }

Results in:

032       20

 034  "    22

rzhaley 0 Newbie Poster · Answer 4 · 2009-12-09T00:55:10+00:00

here's what i put.
main

using System;

class Class
{
      private void button3_Click(object sender, EventArgs e)
    {
       Class class1 = new Class();
       Class.RunProgram();
    }
}

and then Class

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace daniweb
{
   public static class Class
   {
      private class IntegerPair
      {
         private int _min;
         private int _max;
         public int Min { get { return _min; } }
         public int Max { get { return _max; } }
         private IntegerPair() { }
         public IntegerPair(int Min, int Max)
            : this()
         {
            this._min = Min;
            this._max = Max;
         }
      }
      private static string GetDisplayString(char c)
      {
         if (char.IsWhiteSpace(c))
            return c.ToString();
         else if (char.IsControl(c))
            return "control";
         else
            return c.ToString();
      }

      public static void RunProgram()
      {
         //from 32 to 100 and then from 225-250
         List<IntegerPair> lst = new List<IntegerPair>();
         lst.Add(new IntegerPair(32, 100));
         lst.Add(new IntegerPair(225, 250));
         foreach (IntegerPair ip in lst)
         {
            for (int i = ip.Min; i <= ip.Max; i++)
            {
               char c = (char)i;
               string display = GetDisplayString(c);
               Console.Write(string.Format("{0: 000}{1, 3}{0, 6:X2}\n", i, display));
            }
         }
      }
   }
}

and then from that it says that Class doesn't contain a definition for RunProgram()

You shouldnt use reserved words for Class/Member names. Why have you changed public static class DisplayPairs to public static class Class ?

Also, the class has been declared as static so you dont need to create an instance of it, static means that there is only ever one instance that exists without being manually instantiated and is refered to by its name. You have correctly called the method: Class.RunProgram(); but by naming the Class as Class you are causing the error.

Also, if the class wasnt static and required instantiating, your code wouldnt work because you are calling the method from the Class not the object of the Class:

Class class1 = new Class();
Class.RunProgram();

//if Class wasnt static, method call should be:
Class class1 = new Class();
class1.RunProgram();
