c# - .Net - Join together all item of a list in a output string

How can I write a Linq expression (or anything else) that select item from a List and join them together ?

Example

IList<string> data = new List<string>();

data.Add("MyData1");
data.Add("MyData2");

string result = //some linq query... I try data.Select(x => x + ",");

//result = "MyData1, MyData2"

Why not just go with (String.Join Method)

string joined = String.Join(",", data.ToArray());

But if it has to be LINQ, you could try

string joinedLinq = data.Aggregate((i, j) => i + "," + j);
