Q:

C# How to replace multiple chars in string at the same time?

I have a problem. I'm making the 1337 7r4|\|5l4704 (leet speak translator) and i want to have multiple chars to replace with one other.
for example I want to replace "A" and "a" with "4" in one command. I have something like this:
    private void button1_Click(object sender, EventArgs e)
    {
        textBox2.Text = "";
        string a = textBox1.Text;
        string sr = a.Replace("A", "4");
        textBox2.Text = sr;
    }

How can I do it?

A:

Try
string sr = a.Replace('A', '4').Replace('a', '4');
