Compare SortedList problem.

[dennycrane]

This code almost works. There is a problem with the compare constructor. Something is wrong there because it shows everything as correct. Any ideas?

public void ChkSp()
        {

            SortedList SL = new SortedList();
            SortedList SL2 = new SortedList();
            
            SL.Add(0, "Value1");
            SL.Add(1, "Value2");
            SL.Add(2, "Value3");
            SL.Add(3, "Value4");

            SL2.Add(0, richTextBox1.Text);
            SL2.Add(1, richTextBox1.Text);
            SL2.Add(2, richTextBox1.Text);
            SL2.Add(3, richTextBox1.Text);
            
            bool equal = Compare(SL, SL2);

            if (equal)
            {
                richTextBox2.Text = "Correct!";
            }
            else
            { 
                richTextBox2.Text = "They differ";
                
            }
        }
        
      
        static bool Compare(SortedList SL, SortedList SL2)
        {

                  if (SL.Count != SL2.Count)
                  {
                      return false;
                  }
                  
               
                 foreach (DictionaryEntry item in SL)
                 {
                     if (!SL2.ContainsKey(item.Key))
                     {
                         
                         return false;
                     }

                   
                 }
            
                
                 return true;
            
                
        }

Hi Dennycrane You are checking a 'Key value(0 to 3)' only, not a value (Value1). Both collection contain same keys(0 to 4). So always return true. You can check the values using "ContainsValue" method instead of 'ContainsKey'. Ex: if (!SL2.ContainsValue(item.Value)) { return false; } Thanks,

That just turns things around. Now everything is different.
