Regex removing double/triple comma in string

Question

I need to parse a string so the result should output like that:

\"abc,def,ghi,klm,nop\"

But the string I am receiving could looks more like tha

Answer 1

Search for ,,+ and replace all with ,.

So in C# that could look like

resultString = Regex.Replace(subjectString, ",,+", ",");

,,+ means "match all occurrences of two commas or more", so single commas won't be touched. This can also be written as ,{2,}.
