If you are trying out this exercise, you might have run into the same problem I did, it won't work! :<
The problem is two fold, one is they told tell you that you have to have a private DataSet variable declared in your code and second, it has to be a class member variable, not a method variable for the load schema or load data.
My code looks something like this. If got it to run, great! If not, hopefully this will help.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace pch10_LoadDataSetsWithXml
{
public partial class Form1 : Form
{
DataSet northwindDataSet = new DataSet();
public Form1()
{
InitializeComponent();
}
private void LoadDataButton_Click(object sender, EventArgs e)
{
northwindDataSet.ReadXml(@"c:\temp\Northwind.xml");
Console.WriteLine("Done loading");
}
private void loadSchemaButton_Click(object sender, EventArgs e)
{
northwindDataSet.ReadXmlSchema(@"c:\temp\Northwind.xsd");
customersDataGridView.DataSource = northwindDataSet.Tables["Customers"];
ordersDataGridView.DataSource = northwindDataSet.Tables["Orders"];
}
}
