我搜索并发现这个代码是为了将数据保存到数据库, 连接字符串是正常的, 没有例外/错误被丢弃, 但我不知道为什么这个代码没有将数据保存到我的数据库中。

    string query = "Insert Into BookConfiguration (BookNum, x_axis, y_axis, BookName) Values (@BookNum, @x_axis, @y_axis, @BookName)";
    string connStr = "Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\BookShelf.mdf;Integrated Security=True;User Instance=True";


    try
    {
        using (SqlConnection conn = new SqlConnection(connStr))
        {                   
                SqlDataAdapter da = new SqlDataAdapter();
                da.InsertCommand = new SqlCommand(query, conn);
                da.InsertCommand.Parameters.Add("@BookNum", SqlDbType.Int).Value = quantity;
                da.InsertCommand.Parameters.Add("@x_axis", SqlDbType.Int).Value = x;
                da.InsertCommand.Parameters.Add("@y_axis", SqlDbType.Int).Value = y;
                da.InsertCommand.Parameters.Add("@BookName", SqlDbType.Text).Value = openFileDialog1.FileName;
            conn.Open();    

            da.InsertCommand.ExecuteNonQuery();

            conn.Close();
        }
    }

    catch (SqlException ex)
    {
        MessageBox.Show("Error Occured " + ex.Message);
    }

EDIT i have now changed the code same problem

代码 :

        try
        {
            using (TransactionScope scope = new TransactionScope())
            {

                using (SqlConnection conn = new SqlConnection(connStr))
                {
                    conn.Open();
                    using (SqlCommand cmd = new SqlCommand(query, conn))
                    {
                        cmd.Parameters.Add(new SqlParameter("@BookNum", quantity));
                        cmd.Parameters.Add(new SqlParameter("@x_axis", x));
                        cmd.Parameters.Add(new SqlParameter("@y_axis", y));
                        cmd.Parameters.Add(new SqlParameter("@BookName", openFileDialog1.FileName));
                        cmd.ExecuteNonQuery();
                    }
                    conn.Close();
        }

                scope.Complete();
            }
        }

我希望这不含糊...
