OracleConnectionStringBuilder.Keys 属性

public:
 virtual property System::Collections::ICollection ^ Keys { System::Collections::ICollection ^ get(); };

public override System.Collections.ICollection Keys { get; }

member this.Keys : System.Collections.ICollection

Public Overrides ReadOnly Property Keys As ICollection

属性值

一个 ICollection，它包含 OracleConnectionStringBuilder 中的键。

示例

以下控制台应用程序示例新建一个 OracleConnectionStringBuilder。 该代码循环访问显示键/值对的 ICollection 属性返回的 Keys。

// 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;

        // Loop through the collection of keys, displaying
        // the key and value for each item.
        foreach (string key in builder.Keys)
            Console.WriteLine("{0}={1}", key, builder[key]);

        Console.WriteLine();
        Console.WriteLine("Press Enter to continue.");
        Console.ReadLine();
    }
}

' You may have 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

    ' Loop through the collection of keys, displaying 
    ' the key and value for each item.
    For Each key As String In builder.Keys
      Console.WriteLine("{0}={1}", key, builder(key))
    Next

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