OracleConnectionStringBuilder.Item Property

Gets or sets the value associated with the specified key. In C#, this property is the indexer.

Namespace:  System.Data.OracleClient
Assembly:  System.Data.OracleClient (in System.Data.OracleClient.dll)

public override Object this[
	string keyword
] { get; set; }

Parameters

keyword

The key of the item to get or set.

keyword is a null reference (Nothing in Visual Basic).

KeyNotFoundException

Tried to add a key which does not exist within the available keys.

FormatException

Invalid value within the connection string (specifically, when a Boolean or numeric value was expected but not supplied).

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.

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();
    }
}
