如何替换文本框中的字符

Question

I have a text box where the user must enter a text, I want to make a control on the input (ie replace the character ' and ' by another character or delete it from the text entered by the user.

I tried with textbox.TrimEnd() or textbox.Replace(', abc) but I get no results

Answer 1

string.Replace() should have strings as arguments.

This will not work:

textbox.replace(',abc)

As the character ' is not a string or even a character as far as the interpreter is concerned. And of course, if abc is a string variable you may use abc .

Try instead:

textbox.text.Replace("'", "abc")

Note the '.text' so you can access the text in what I'm assuming to be a textbox object with a text property.

Answer 2

I suggest you to use

textbox.Replace("'", "new value") Iwish this help you brother
