c# - 如何使用c#将数据添加到mysql中的指定列

Question

如何使用c#按钮单击将数据添加到mysql数据库表中的指定列中，一旦我单击按钮，它将传递给catch

这是我的添加按钮代码

 private void Button_add_Click(object sender, RoutedEventArgs e)
    {
        try
        {
            string Query = @"INSERT INTO `bcasdb`.`tbl_department`(
                `dep_id`,
                `dep_name`,
                `tbl_branch_branch_id`) 
        VALUES (" 
               + this.depIDInput.Text + ",'" 
               + this.depnameInput.Text + "','" 
               + this.dep_branchIDInput.Text + "')";
            //This is command class which will handle the query and connection object.
            MySqlConnection conn = new MySqlConnection(BCASApp.DataModel.DB_CON.connection);
            MySqlCommand cmd = new MySqlCommand(Query, conn);
            MySqlDataReader MyReader;
            conn.Open();
            MyReader = cmd.ExecuteReader();// Here our query will be executed and data saved into the database.           
            conn.Close();
            successmsgBox();
        }
        catch (Exception)
        {
            errormsgBox();
        }
    }

这是表格的所有列，

INSERT INTO `bcasdb`.`tbl_student`
(`reg_id`,
`std_fname`,
`std_lname`,
`tbl_batch_batch_id`,
`gender`,
`dob`,
`email`,
`mobile`,
`contact_address`,
`home_address`,
`status`,
`course_id`,
`depart_id`,
`parent_name`,
`telephone`,
`nationality`,
`nic`,
`passport_no`,
`acadamic_qulification`,
`current_employement`,
`gce_ol`,
`gce_al`,
`birth_certifiacte`,
`copy_of_nic`,
`police_clerence`,
`tbl_studentcol`)
VALUES

我相信您的代码应该重写如下:

    private void Button_add_Click(object sender, RoutedEventArgs e)
    {
        try
        {
            string Query = @"INSERT INTO `bcasdb`.`tbl_department`(
            `dep_id`,
            `dep_name`,
            `tbl_branch_branch_id`) 
            VALUES (@depId, @depName, @branchId)";
            //This is command class which will handle the query and connection object.
            using (MySqlConnection conn = new MySqlConnection(BCASApp.DataModel.DB_CON.connection))
            {
                conn.Open();
                using (MySqlCommand cmd = new MySqlCommand(Query, conn))
                {
                    cmd.Parameters.Add("@depId", this.depIDInput.Text);
                    cmd.Parameters.Add("@dep_name", this.depnameInput.Text);
                    cmd.Parameters.Add("@branchId", this.dep_branchIDInput.Text);

                    cmd.ExecuteNonQuery();
                }
            }

            successmsgBox();
        }
        catch (Exception)
        {
            errormsgBox();
        }
    }
