Examples

The following code, in a console application, creates a new OracleConnectionStringBuilder and adds key/value pairs to its connection string, using the Item[] property.

// You may need to set a reference to the System.Data.OracleClient
// assembly before you can run this sample.
using System.Data.OracleClient;

class Program
{
    static void Main()
    {
        OracleConnectionStringBuilder builder =
            new OracleConnectionStringBuilder();
        builder["Data Source"] = "localhost";
        builder["integrated security"] = true;
        builder["Unicode"] = true;

        // Overwrite the existing value for the Data Source value.
        builder["Data Source"] = "NewOracleDemo";

        Console.WriteLine(builder.ConnectionString);
        Console.WriteLine();
        Console.WriteLine("Press Enter to continue.");
        Console.ReadLine();
    }
}

' You may need to set a reference to the System.Data.OracleClient
' assembly before you can run this sample.
Imports System.Data.OracleClient

Module Module1
  Sub Main()
    Dim builder As New OracleConnectionStringBuilder
    builder.Item("Data Source") = "OracleDemo"
    ' Item is the default property, so 
    ' you need not include it in the reference.
    builder("integrated security") = True
    builder.Item("Unicode") = True

    ' Overwrite the existing value for the Data Source value.
    builder.Item("Data Source") = "NewOracleDemo"

    Console.WriteLine(builder.ConnectionString)
    Console.WriteLine()
    Console.WriteLine("Press Enter to continue.")
    Console.ReadLine()
  End Sub
End Module

Remarks

Because the OracleConnectionStringBuilder contains a fixed-size dictionary, trying to add a key that does not exist within the dictionary throws a KeyNotFoundException. The following table lists all the possible keys within the connection string, and the default value for each.
