Remove duplicate comma from list

Hi,

Recently on ASP.NET forum there was post for removing duplicate ',' from a comma saperated string.

This is using Regex

string abodes = ",House,,,,Apartment,,,Villa,,,,Townhouse,,,,";
Regex regx = new Regex(@",+");
abodes = regx.Replace(abodes, ",").Trim(',');

And now let's see using LINQ

string abodes = ",House,,,,Apartment,,,Villa,,,,Townhouse,,,,"; 
string cleanAbodes = string.Join(",", abodes.Split(',').Where(a => a != string.Empty).ToArray());

Have Fun with LINQ
