Examples

The following example creates a new SqlConnectionStringBuilder and assigns a connection string in the object's constructor. The code displays the parsed and recreated version of the connection string, and then modifies the ApplicationName property of the object. Finally, the code displays the new connection string, including the new key/value pair.

using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        try
        {
            string connectString = "Server=(local);Initial Catalog=AdventureWorks;" +
                "Integrated Security=true";
            SqlConnectionStringBuilder builder =
                new SqlConnectionStringBuilder(connectString);
            Console.WriteLine("Original: " + builder.ConnectionString);
            Console.WriteLine("ApplicationName={0}",
                builder.ApplicationName);

            builder.ApplicationName = "My Application";
            Console.WriteLine("Modified: " + builder.ConnectionString);

            Console.WriteLine("Press any key to finish.");
            Console.ReadLine();
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
    }
}

Imports System.Data.SqlClient

Module Module1

    Sub Main()
        Try
            Dim connectString As String = _
             "Server=(local);Initial Catalog=AdventureWorks;" & _
                 "Integrated Security=True"
            Dim builder As New SqlConnectionStringBuilder(connectString)
            Console.WriteLine("Original: " & builder.ConnectionString)
            Console.WriteLine("ApplicationName={0}", _
                builder.ApplicationName)
            builder.ApplicationName = "My Application"
            Console.WriteLine("Modified: " & builder.ConnectionString)

            Console.WriteLine("Press any key to finish.")
            Console.ReadLine()

        Catch ex As Exception
            Console.WriteLine(ex.Message)
        End Try
    End Sub
End Module

The sample displays the following text in the console window:

Original: Data Source=(local);Initial Catalog=AdventureWorks;Integrated Security=True
ApplicationName=".Net SqlClient Data Provider"
Modified: Data Source=(local);Initial Catalog=AdventureWorks;Integrated Security=True;Application Name="My Application"

Remarks

This property corresponds to the "Application Name" and "app" keys within the connection string.
