replace method 1

[jshurst]

I would like strip certain characters out of a string. I can do this easily for one character.

Dim a as string
a = txtName.text.replace("*","")

But what if I want to replace more than one character (a list of characters)? Should I do this...

Dim a as string
a = txtName.text.replace("*","").replace("#","")...

Or perhaps loop through somehow? I guess I'm asking for the best way to do this.

Thanks.

I'm wondering if you could use a Regular Expression to do this...

"...we both know I'm training to become a cagefighter...see what happens if you try 'n hit me..."

Here's a simple Regex that replaces all of the characters between the brackets with "". Should be simple enough to convert to vb.

[COLOR=blue]public[/color] [COLOR=blue]static[/color] [COLOR=blue]string[/color] CleanMyString([COLOR=blue]string[/color] inputText)
        {
            Regex regex = [COLOR=blue]new[/color] Regex(@"[@!#$%^&*]",RegexOptions.IgnoreCase);]
            [COLOR=blue]string[/color] cleanString = regex.Replace(inputText,"");
            [COLOR=blue]return[/color] cleanString;
        }

Thanks a lot that works perfectly.

Just converted the Above code in VB.NET in case anyone needs it. It is not tested, so I hope it works.

imports system.text.regularexpressions

public function CleanMyString(byval inputText as string) as string
  Dim MyRegex as new Regex("[@!#$%^&*", RegexOptions.IgnoreCase)
  Dim cleanString as strng = MyRegex.Replace(inputText, "")
  return cleanString
End function
