Convert an array of integers for use in a SQL “IN” clause

Question

Surely there is a framework method that given an array of integers, strings etc converts them into a list that can be used in a SQL \"IN\" clause?

e.g.

Answer 1

If you don't have access to the .NET 3.5 extension methods, you can do this:

StringBuilder sb = new StringBuilder();
sb.Append('(');

foreach (int i in values) {
    sb.Append(i).Append(',');
}

// remove final ,
sb.Length -= 1;
sb.Append(')');

string inValue = sb.ToString();

Which'll work on .NET 2
