Multiple variables in for each loop.

OK. I am working on getting my SQL Insert command working correctly. Currently I have:

private void testButton_Click(object sender, EventArgs e)
        {
            
            try
            {
                //Create OleDB connection
                OleDbConnection connection = new OleDbConnection();
                connection.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0; Data Source=I:\PSC SHARED\accessdb.accdb;
Persist Security Info=False;";
                
                //connect to DB
                connection.Open();

                //Setup 
                var ComboBoxList = Controls.OfType<ComboBox>();
                OleDbCommand command = new OleDbCommand();
                command.Connection = connection;

                //Insert data into table through loop
                foreach(ComboBox taskComboBox in ComboBoxList)
                {
                    string query = "INSERT INTO MasterTable(Task, TimeWorked, RefDate, Analyst, HoursWorked) values('" + taskComboBox.Text + "', '" + stopwatch1.Elapsed.ToString("hh\\:mm\\:ss") + "', '" + ReferenceDate + "', '" + AnalystName + "', '" + (stopwatch1.Elapsed.TotalMinutes / 60d).ToString("N2") + "')";
                    command.CommandText = query;
                    command.ExecuteNonQuery();
                }
                
                //close connection to db
                connection.Close();
            }
            //handle errors
            catch (Exception ex)
            {
                MessageBox.Show("Error: " + ex);
            }
        }

To my surprise, I almost got this working completely. The "foreach" works, executing the command for each combobox on the form. All work except for the 2, TimeWorked and HoursWorked. It repeats the values of stopwatch1. This makes sense because I specified which stop watch to reference.

What I need to know:
How to do get the stop watch information to "marry-up" with the appropriate ComboBox in the loop?

Please let me know if you need additional information and thank you for your time!!!
