Replace the string of special characters in C#

Question

My requirement is:

I have to replace some special characters like * ' " , _ & # ^ @ with string.Empty, and I have to replace blank spaces with -.

This is my code:

 Charseparated = Charseparated
    .Replace("*","")
    .Replace("'","")
    .Replace("&","")
    .Replace("@","") ...

For so many characters to replace I have to use as many as Replace's which I want to avoid.

Is there another efficient way to remove the special characters, but at the same time replace blank spaces with -?

Answer 1

I believe, best is to use a regular expression here as below

s/[*'",_&#^@]/ /g

You can use Regex class for this purpose

Regex reg = new Regex("[*'\",_&#^@]");
str1 = reg.Replace(str1, string.Empty);

Regex reg1 = new Regex("[ ]");
str1 = reg.Replace(str1, "-");
