System.InvalidOperationException: ExecuteNonQuery: Connection Property Has Not Been Initialized

Question

Why is my connection not being initialized?  It seems to me in my syntax I set it up as it should be.  How can I get around this so the connection will be initialized?  I am needing to have a re-usable function as the database parameter needs
to be passed into the connection string.
public static void DoSomething_Click()
string database = "1234";
OleDbConneciton olc = new OleDbConnection(AccessConnection(database));
olc.Open();
try
OleDbCommand command = new OleDbCommand();
command.CommandText = ATS;
command.CommandType = CommandType.Text;
command.ExecuteNonuery();
command.Dispose();
catch (Exception wtf) { Messagebox.show(wtf.ToString()); }
private static string AccessConnection(string database)
return string.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source = C:\\Test\\{0}.mdb", database);

Answer 1

You've set up a connection, and a command, but you didn't associate the two. The command you have set up needs to know what connection to use. You haven't set that up.
command.Connection = olc;
