Delete a string using replace keyword

Question

I have a problem with String.Replace method. It is not working for buttonclick events.

i use this code

private void button4_Click(object sender, EventArgs e)
{
       textBox3.Text.Replace("apple","");
}

Please see the image

When I press clear button it doesn't remove "apple" words

`testBox3.Text = textBox3.Text.Replace("apple","");` simple fix would have been to read up on the string.Replace() function — MethodMan, Dec 19 '17 at 02:30
It is well knows fact that [C# string replace does not work](https://www.bing.com/search?q=c%23+string+replace+does+not+work). — Alexei Levenkov, Dec 19 '17 at 02:33

The replace function does not change the control, it returns a new string.

If textBox3 says "applebananacherry"

String text = textBox3.Text.Replace("apple","");

would leave text with "bananacherry"

What you need is

textBox3.Text = textBox3.Text.Replace("apple", "");

If you only want to remove the first apple: int index = textBox3.Text.IndexOf("apple"); if (index > -1) textBox3.Text = s.Remove(index, "apple".Length); – NeedsAnswers Dec 20 '17 at 01:26
