取得 ICollection 中包含索引鍵的 OracleConnectionStringBuilder。
public:
virtual property System::Collections::ICollection ^ Keys { System::Collections::ICollection ^ get(); };public override System.Collections.ICollection Keys { get; }member this.Keys : System.Collections.ICollectionPublic Overrides ReadOnly Property Keys As ICollection屬性值
ICollection 中包含索引鍵的 OracleConnectionStringBuilder。
範例
下列主控台應用程式範例會建立新的 OracleConnectionStringBuilder。 此程式碼會針對 ICollection 屬性傳回的 Keys 執行迴圈，以顯示索引鍵/值組。
// 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
備註
雖然 ICollection 中值的順序並未指定，但此順序會與 ICollection 屬性傳回之 Values 中關聯值的順序相同。
