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()

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.
