Hello,

little issue I have
(otherwise I wouldn't be asking :)

I need to replace blank spaces in textbox with another character, I tried

string.Replace

like this

string text = textbox.Text;

textbox.Text = "NEED HELP";
text.Replace(" ", "_");
string text1 = text;

but nothing happens

instead of " ", "_" I tried ' ', '_', still nothing, I tried string.Empty, "_", still nothin, it throws an error on that one that he old value can not be zero length

I just want to while I type in textbox some text when I hit spacebar to divide words a character _ comes there, that's all

forget I asked, found a solution, and not my credit of course for this idiotic question I had

text1 = text.Replace(@" ", "_");

so stupid for asking while people have serious issues to deal with

Indeed, string.Replace function returns a string that you have to assign to your variable.
It can't be used the way you did first time; it does not modify the provided source-string.
You should mark this question as answered; and better: create an answer to this question explaining the problem and its solution. This way someone might better understand the correct usage of string.Replace method.
Cheers.

Solution 1

You just forgot assign result of Replace operation to text. Everything else was/is fine.

C#

text = text.Replace(" ", "_");
