プロパティ値

DataSource プロパティの値。値が指定されていない場合は EmptyThe value of the DataSource property, or Empty if none has been supplied.

次の例を示しますOracleConnectionStringBuilderクラスは、よく知られているキーに"Data Source"接続文字列のキーのシノニムを変換します。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

End Module

注釈

このプロパティは、接続文字列内の"Data Source"および"Server"キーに対応します。This property corresponds to the "Data Source" and "Server" keys within the connection string. 上記のどの値が指定された接続文字列内で指定されてに関係なく、によって作成された接続文字列、OracleConnectionStringBuilderよく知られている"Data Source"キーが使用されます。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. このプロパティの設定を試行した際に、渡された値が null である場合、DataSource プロパティはリセットされます。If the value passed in is null when you try to set the property, the DataSource property is reset. 戻り値は、値が設定されていないと、開発者がプロパティを取得しようとした場合、Emptyします。If the value has not been set and the developer tries to retrieve the property, the return value is Empty.
