C＃Mysql参数问题

Question

I'm trying to write a query to my database. When I originally wrote it I didn't use parameters, I am now trying to do so But I am getting a Mysql Error now.

Column count doesn't match value at row1

Which in my 1st column I have an auto Incremented number labeled as " ID " Which I do not believe I have to add to the query because of the auto increment..

This is the newly written code:

            MySqlConnection conn = new MySqlConnection(dbConnection);
            string Query = "INSERT INTO tasklist.tasks (TaskName, AssignedTo, StartDate, EndDate, Description, DirPath, Completed) VALUES (?TaskName),(?AssignedTo),(?StartDate),(?EndDate),(?Description),(?DirPath),(?Completed);";

            MySqlCommand insertCommand = new MySqlCommand(Query, conn);

            conn.Open();

            insertCommand.Parameters.AddWithValue("?TaskName", txtTaskName.Text);
            insertCommand.Parameters.AddWithValue("?AssignedTo", txtAssignTo.Text);
            insertCommand.Parameters.AddWithValue("?StartDate", txtdateStart.Value.ToString("yyyy-M-d"));
            insertCommand.Parameters.AddWithValue("?EndDate", txtDateEnd.Value.ToString("yyyy-M-d"));
            insertCommand.Parameters.AddWithValue("?Description", txtTaskDescription.Text);
            insertCommand.Parameters.AddWithValue("?DirPath", txtDirPath.Text);
            insertCommand.Parameters.AddWithValue("?Completed",("0"));

            insertCommand.ExecuteNonQuery();

            conn.Close();

Remember the previous way without parameters worked... however with parameters does not work. What exactly am I doing wrong here? Any help would be greatly appreciated.

Use only one pair of parentheses around all parameters

INSERT INTO tasklist.tasks (TaskName, AssignedTo, StartDate, EndDate, Description, DirPath, Completed) 
VALUES (?TaskName, ?AssignedTo, ?StartDate, ?EndDate, ?Description, ?DirPath, ?Completed)
