Connecting to a MySQL Database in ADO.NET

This article has been excerpted from the book "A Programmer's Guide to ADO.NET in C#".
As you can see, working with different data sources means nothing except changing the connection string. Listing 5-27 shows the connection string for the MySQL database. You access a MySQL database through odbc data providers. (I'll discuss My SQL database connectivity and show how to install an ODBC driver for MySQL with a step-by-step example later article). As you can see from Listing 5-27, you can use a similar database as Northwind. To provide a similar sample, I exported the Access 2000 Northwind database as a MySQL database. You can use any database. Just replace the database name and change the SQL statement. To test this application, create a Windows application, drop a data grid to the form, add a reference to the System.Data and Microsoft.Data.Odbc namespaces, and type the following code in Listing 5-27 on the Form_load event.
Listing 5-27. Reading data from a MySQL database using ODBC
  1. private void Form1 _Load(object sender, System. EvetArgs e)  
  2. {  
  3.             string ConnectionString = "Driver={MySQL};SERVER = localhost; " + "DATABASE= NorthwindMySQL; ";  
  4.             OdbcConnection conn = new OdbcConnection(ConnectionString);  
  5.             conn.Open();  
  6.             OdbcDataAdapter da = new OdbcDataAdapter  
  7.             ("SELECT CustomerID, ContactName, ContactTitle FROM Customers", conn);  
  8.             DataSet ds = new DataSet("cust");  
  9.             da.Fill(ds, "Customers");  
  10.             dataGrid1.DataSource = ds.DefaultViewManager;  
  11.             conn.Close();
