Question

What I’m trying to do is type in random words into box1, click a button and then print all the words that start with “D” in box2. So if I was to type in something like “Carrots Doors Apples Desks Dogs Carpet” and click the button “Doors Desks Dogs” would print in box2.

    string s = box1.Text;                
    int i = s.IndexOf("D");
    string e = s.Substring(i);
    box2.Text = (e);

when I use this^^
It would print out “Doors Apples Desks Dogs Carpet” instead of just the D’s.
NOTE: These words are an example, I could type anything into box1.

Any help?

You could simplify this by using LINQ

var allDWords = box1.Text.Split(' ').Where(w => w.StartsWith("D"));
box2.Text = String.Join(" ", allDWords);
