multiplying a variable without rewriting it

So I am fairly new to the "code world" and hopefully have a fairly simply question. 

txtBox.Text = "x";

How would I make it so I am able to see 10 X's in my txtBox without completely writing it out?

string has a constructor that repeats a character for a given number of times:

txtBox.Text = new string('x', 10);

It's documented here.

If what you want to repeat is a string (not a single character) you need a loop, but use a StringBuilder to minimise memory fragmentation. Try avoiding repetitive string concatenations:

var stringBuilder = new StringBuilder();
for(int i = 0; i < 10; i++)
    stringBuilder.Append("ThePatternToRepeat");

txtBox.Text = stringBuilder.ToString();

string has a constructor for this :- 

txtBox.Text = new string('x',10);

alternatives are

looping:

  string s = "";
    for (var n = 0; n < 10; n++) s += "x";
    txtBox.Text = s;

Linq:

txtBox.Text =  Enumerable.Range(0, 10).Aggregate("", (a, n) => a + "x");
