Connecting to a MySQL Database in ADO.NET

This article has been excerpted from book "A Programmer's Guide to ADO.NET in C#".

As you can see, working with different data source 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 databases 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 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

void Form1 _Load(object sender, System. EvetArgs e)

            string ConnectionString = "Driver={MySQL};SERVER = localhost; " + "DATABASE= NorthwindMySQL; ";
            OdbcConnection conn = new OdbcConnection(ConnectionString);
            OdbcDataAdapter da = new
            ("SELECT CustomerID, ContactName, ContactTitle FROM Customers", conn);
            DataSet ds = new DataSet("cust");
            da.Fill(ds, "Customers");
            dataGrid1.DataSource = ds.DefaultViewManager;
