OracleConnectionStringBuilder.DataSource 屬性

定義

命名空間:

System.Data.OracleClient

組件:

System.Data.OracleClient.dll

取得或設定要連接之 Oracle 資料來源的名稱。

public:
 property System::String ^ DataSource { System::String ^ get(); void set(System::String ^ value); };

public string DataSource { get; set; }

member this.DataSource : string with get, set

Public Property DataSource As String

屬性值

String

DataSource 屬性的值，如未提供任何值，則為 Empty。

範例

下列範例示範 類別OracleConnectionStringBuilder會將 「Data Source」 連接字串 索引鍵的同義字轉換成已知的索引鍵。

// 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

End Module

備註

此屬性會對應至 連接字串 內的「數據源」和「伺服器」索引鍵。 無論在提供的 連接字串 中提供哪些值，由 所OracleConnectionStringBuilder建立的 連接字串 都會使用已知的「數據源」索引鍵。 如果當您嘗試設定此屬性時，傳入的值為 null，則會重設 DataSource 屬性。 如果尚未設定值，而且開發人員嘗試擷取 屬性，則傳回值為 Empty。
