Regex replace consecutive non-alpha chars with single char

Question

I want to replace all non-alpha characters in a string with a plus '+' sign, but making sure that a group of more than one non-alpha chars is only replaced by one plus sign.

I had thought the following might work but apparently not:

System.Text.RegularExpressions.Regex.Replace(name, @"[^\w]*?", "+")

Answer 1

Try System.Text.RegularExpressions.Regex.Replace(name, @"\W+", "+")

For this: "sasa-==[]&^asdsa2435" matches -==[]&^

Answer 2

You should not disable greediness, and you want 1 or more, not 0 or more. Replace "*?" with "+".
