I have multiple text blocks I want to compare the text values of with whatever the current random value is in my array, so I can "gray out" the text block when it gets "opened".

This code works for 1 text block, but I was wondering how I could do it for all 26 of my blocks w/o having to type out each one? Is there a way I can reference all my blocks, kind of like using the same click event for all my buttons?

if (money[turns]==Convert.ToInt32(tb0.Text))
                    {
                        tb0.Foreground = Brushes.Gray;
                    }

  • Why don't you loop through all your `TextBox`es doing this validation? You have them in the `Controls` property of the form, just check its type to make sure it's the one you are interested in. – Andrew Jan 04 '16 at 17:32

    What is the application type? Forms? WPF? – Alexei - check Codidact Jan 04 '16 at 17:32
  • You're asking the wrong question. When you need to do this, it's almost always a design smell. You should use data binding, or the tag or name to identify which control displays what. Anyway "[your UI framework] find all controls" will yield plenty of results. – CodeCaster Jan 04 '16 at 17:35
  • Sorry! WPF is the application type. The list solution worked perfectly for me and what I was looking for. – Audie Jan 05 '16 at 18:09

If Windows.Forms you can iterate through all your controls of type TextBox and compare your text to the one in each TextBox. The code should like this:

bool exists = GetAll(this, typeof(TextBox)).Any(t => t.Text.Equals(yourText));

As already suggested, it would be better to use databinding and do the search in your objects, rather than into your interface.

As addition to Alexei, if you want only compare specific TextBlock, first you can insert your TextBlock into a List 

List<TextBlock> listTextBlock = new List<TextBlock>();
list.Add(tb0);
list.Add(tb1);

... so you just using loop to check each TextBlock.

foreach(TextBlock item in listTextBlock)
{
   if (money[turns]==Convert.ToInt32(item.Text))
   {
      item.Foreground = Brushes.Gray;
   }
}
