Examples

The following example demonstrates that the SqlConnectionStringBuilder class converts synonyms for the "Data Source" connection string key into the well-known key:

using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder(
            "Network Address=(local);Integrated Security=SSPI;" +
            "Initial Catalog=AdventureWorks");

        // Display the connection string, which should now 
        // contain the "Data Source" key, as opposed to the 
        // supplied "Network Address".
        Console.WriteLine(builder.ConnectionString);

        // Retrieve the DataSource property.
        Console.WriteLine("DataSource = " + builder.DataSource);

        Console.WriteLine("Press any key to continue.");
        Console.ReadLine();
    }
}
Imports System.Data.SqlClient

Module Module1

    Sub Main()
        Dim builder As _
         New SqlConnectionStringBuilder( _
         "Network Address=(local);Integrated Security=SSPI;" & _
         "Initial Catalog=AdventureWorks")

        ' Display the connection string, which should now 
        ' contain the "Data Source" key, as opposed to the 
        ' supplied "Network Address".
        Console.WriteLine(builder.ConnectionString)

        ' Retrieve the DataSource property:
        Console.WriteLine("DataSource = " & builder.DataSource)

        Console.WriteLine("Press any key to continue.")
        Console.ReadLine()
    End Sub
End Module

Remarks

This property corresponds to the "Data Source", "server", "address", "addr", and "network address" keys within the connection string. Regardless of which of these values has been supplied within the supplied connection string, the connection string created by the SqlConnectionStringBuilder will use the well-known "Data Source" key.
