It’s hard to understand what is your code supposed to do and it seems you don’t understand what do Rows, Columns, and ItemArray mean. You should probably read their documentation.

What I think you’re trying to do is something like this:

var row = ds1.Tables[0].Rows[0];

DateTime lastLogin = (DateTime)row["Last_login"];
Int32 snapno = (Int32)row["snapno"];
string membership = (string)row["membership"]:
