Convert a list of strings to a single string

Question

List<string> MyList = (List<string>)Session["MyList"]; 

MyList contains values like: 12 34 55 23.

I tried using the code below, however the values disappear.

string Something = Convert.ToString(MyList); 

I also need each value to be separated with a comma (",").

How can I convert List<string> Mylist to string?

Answer 1

string Something = string.Join(",", MyList); 

Answer 2

Try this code:

var list = new List<string> {"12", "13", "14"}; var result = string.Join(",", list); Console.WriteLine(result); 

The result is: "12,13,14"
