Question

I have a URL formatter in my application but the problem is that the customer wants to be able to enter special characters like:

: | / – “ ‘ & * # @

I have a string:

string myCrazyString  = ":|/-\“‘&*#@";

I have a function where another string is being passed:

public void CleanMyString(string myStr)
{
} 

How can I compare the string being passed “myStr” to “myCrazyString” and if “myStr has any of the characters in myCrazyString to remove it?

So if I pass to my function:

“this ‘ is a” cra@zy: me|ssage/ an-d I& want#to clea*n it”

It should return:

“this is a crazy message and I want to clean it”

How can I do this in my CleanMyString function?

Use Regular Expression for that Like:

pattern = @"(:|\||\/|\-|\\|\“|\‘|\&|\*|\#|\@)";

System.Text.RegularExpressions.Regex.Replace(inputString, pattern, string.Empty);

• split each string you want to remove by |
• To remove the special characters like the | itself use \, so \| this will handle the | as normal character.

Test:

inputString = @"H\I t&he|r#e!";
//output is: HI there!
