次の例では、呼び出す場合の効果、Clearメソッド。The following example demonstrates the effect of calling the Clear method. この例では、OracleConnectionStringBuilder にいくつかのキー/値ペアを設定してから、Clear メソッドを呼び出して結果を表示しています。This example populates the OracleConnectionStringBuilder with some key/value pairs, and then calls the Clear method and shows the results.

// You may need to set a reference to the System.Data.OracleClient
// assembly before running this example.
using System.Data.OracleClient;

class Program
{
    static void Main()
    {
        OracleConnectionStringBuilder builder =
            new OracleConnectionStringBuilder();
        builder.DataSource = "OracleSample";
        builder.IntegratedSecurity = true;
        Console.WriteLine("Initial connection string: " +
            builder.ConnectionString);

        Console.WriteLine("Before call to Clear, count = " + builder.Count);
        builder.Clear();
        Console.WriteLine("After call to Clear, count = " + builder.Count);
        Console.WriteLine("Cleared connection string: " +
            builder.ConnectionString);
        Console.WriteLine();

        Console.WriteLine("Press Enter 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
    builder.DataSource = "OracleSample"
    builder.IntegratedSecurity = True
    Console.WriteLine("Initial connection string: " & builder.ConnectionString)

    Console.WriteLine("Before call to Clear, count = " & builder.Count)
    builder.Clear()
    Console.WriteLine("After call to Clear, count = " & builder.Count)
    Console.WriteLine("Cleared connection string: " & builder.ConnectionString)
    Console.WriteLine()

    Console.WriteLine("Press Enter to continue.")
    Console.ReadLine()
  End Sub
End Module

注釈

Clear メソッドは、OracleConnectionStringBuilder からすべてのキー/値ペアを削除し、対応するプロパティをすべてリセットします。The Clear method removes all key/value pairs from the OracleConnectionStringBuilder, and resets all corresponding properties. これは、接続文字列をリセットする空の文字列に含まれます。This includes resetting the connection string to an empty string.
