Converting Array or List of data to String => made easy! (C#, MVC3, LINQ)

, 18 Jan 2012
I would just use:string.Join(",", cities.Select(c=>c.Name))Since Version 4 of the Framework there is an overloaded versions of string.Join for IEnumerable too. It uses a StringBuilder internally and doesn't insert a seperator after the last element as well.I could't find the Join method...

If you're stuck with .NET 3.5, you can use the Aggregate extension method[^]:string cities_string = cities.Aggregate(new StringBuilder(), (sb, c) =>{ if (0 != sb.Length) sb.Append(", "); sb.Append(c.Name); return sb;}, sb => sb.ToString());
