Voorbeelden

In het volgende voorbeeld ziet u de Count eigenschap zowel vóór als nadat u de inhoud van de ConnectionString eigenschap hebt gewijzigd.

static void Main()
{
    DbConnectionStringBuilder builder = new DbConnectionStringBuilder();
    builder.ConnectionString =
        "Data Source=(local);Initial Catalog=AdventureWorks;" +
        "Integrated Security=SSPI";

    // This should display "3" in the console window.
    Console.WriteLine("Original count: " + builder.Count);

    builder.Add("Connection Timeout", 25);

    // This should display the new connection string and
    // the number of items (4) in the console window.
    Console.WriteLine(builder.ConnectionString);
    Console.WriteLine("New count: " + builder.Count);

    Console.WriteLine();
    Console.WriteLine("Press Enter to finish.");
    Console.ReadLine();
}

Sub Main()
    Dim builder As New DbConnectionStringBuilder
    builder.ConnectionString = _
        "Data Source=(local);Initial Catalog=AdventureWorks;" & _
        "Integrated Security=SSPI"

    ' This should display "3" in the console window.
    Console.WriteLine(builder.Count)

    builder.Add("Connection Timeout", 25)

    ' This should display the new connection string and
    ' the number of items (4) in the console window.
    Console.WriteLine(builder.ConnectionString)
    Console.WriteLine(builder.Count)

    Console.WriteLine()
