.To[Delimited]String – Using LINQ and Extension Methods to provide a delimited ToString method for Array’s, Lists, etc.

CodeProject - Seperator Delimited ToString for Array, List, Dictionary, Generic IEnumerable


In C#, there is an easy way to do ToString with separator delimited for Array, List, Dictionary and Generic IEnumerables by utilizing extension method in .NET

Lets try a simple example without using String.Join directly.

int[] intArray = { 1, 2, 3 };
// output 1,2,3
List<string> list = new List<string>{"a","b","c"};
// output a|b|c


I was just thinking about doing something like this the other day. I have a number of arrays, collections, etc that I need to transform into a delimited string and while taking the fast to code, old school approach (i.e. looping) I knew there had to be a more reusable, cleaner and generally better way.

This project is one example of that better way, by using Linq with extension methods (and String.Join)…

Hi Greg, the link to the CodeProject is broken, I have found the original post at

I hate when that happens... sigh... The joy of being a reblogger. :p

Thank you catching it and for the link.
