Exemplos

O exemplo a seguir demonstra que a OracleConnectionStringBuilder classe converte sinônimos para a chave de cadeia de conexão "fonte de dados" na chave conhecida.The following example demonstrates that the OracleConnectionStringBuilder class converts synonyms for the "Data Source" connection string key into the well-known key.

// 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(
            "Server=OracleDemo;Integrated Security=True");

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

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

        Console.WriteLine("Press any key to continue.");
        Console.ReadLine();
    }
}
' You may need to set a reference to the System.Data.OracleClient
' assembly before running this example.
Imports System.Data.OracleClient

Module Module1

  Sub Main()
    Dim builder As _
     New OracleConnectionStringBuilder( _
     "Server=OracleDemo;Integrated Security=True")

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

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

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

Comentários

Essa propriedade corresponde às chaves "fonte de dados" e "servidor" na cadeia de conexão.This property corresponds to the "Data Source" and "Server" keys within the connection string. Independentemente de qual desses valores tenha sido fornecido na cadeia de conexão fornecida, a cadeia de conexão criada pelo OracleConnectionStringBuilder usará a chave "fonte de dados" conhecida.Regardless of which of these values has been supplied within the supplied connection string, the connection string created by the OracleConnectionStringBuilder will use the well-known "Data Source" key. Se o valor passado for nulo quando você tentar definir a propriedade, a DataSource propriedade será redefinida.If the value passed in is null when you try to set the property, the DataSource property is reset. Se o valor não tiver sido definido e o desenvolvedor tentar recuperar a propriedade, o valor de retorno será Empty .If the value has not been set and the developer tries to retrieve the property, the return value is Empty.
