most elegant way to return a string from List<int>

I’m not sure the easiest way to do this. I simply want to add a ; between each value and spit it out as one string. I don’t see that you can do this with ToString(). I’d have to loop through and create a stringbuilder and append & add a “;”.

UPDATED to use List<int> instead of List<string>

Use string.Join:

List<int> data = ..;
var result = string.Join(";", data); // (.NET 4.0+)
var result = string.Join(";", data.Select(x => x.ToString()).ToArray()); // (.NET 3.5)
