正则表达式替换不正确

Question

I have a string (PointName) that I need to replace any of the following characters with an empty string :/?*'[]. Below is the script I have using c#:

    Regex.Replace(PointName, @"\:/?*'[]", @"")

I tried above but getting the following message:

parsing ":/?*'[]" - Unterminated [] set.

You need to create a Regex object that is associated with the pattern, then use replace.

string pattern = @"[[\]?/\\:*']";
string replacement = " ";
Regex rgx = new Regex(pattern);
string result = rgx.Replace(input, replacement);

You need to use an the OR operation to create the regex statement that eliminates the characters wanted to eliminate. You can not simply just list the characters.
