Passing a SQL parameter to an IN() clause using typed datasets in .NET

Question

First apologies as there are similar questions on this site, but none of them answer this problem directly.

Im using typed datasets in VS 2010. I create a TableAdapt

You also can create a list of IDs parameters so instead of using @IDs you will use @ID1, @ID2, @ID3, etc

var sql = "SELECT * from Table WHERE ID IN (" + getKeys(values.Count) + ")";

And getKeys(count) do something like this:

var result = string.Empty;
            for (int i = 0; i < count; i++)
            {
                result += ", @ID" + i;
            }
            return string.IsNullOrEmpty(result) ? string.Empty : result.Substring(1);

and Finally, add the parameters:

foreach (int i = 0; i < values.Count; i++)
            {
                cmd.Parameters.Add(new SqlParameter("@ID" + i, SqlDbType.VarChar) { Value = values[i]});
            }
