OracleConfigurationクラス

6.4 OracleConfigurationクラス

OracleConfigurationは、単一のプログラミング・インタフェースを使用してODP.NET Core構成データを設定するための静的クラスです。

クラスの継承

System.Object

Oracle.ManagedDataAccess.Client.OracleConfiguration

宣言

// C#
public sealed class OracleConfiguration

要件

プロバイダ	ODP.NET Core
アセンブリ	`Oracle.ManagedDataAccess.dll`
ネームスペース	`Oracle.ManagedDataAccess.Client`
.NET Core	2.1以降

スレッド安全性

パブリック静的メソッドはスレッドセーフですが、インスタンス・メソッドではスレッド安全性は保証されません。

例

// C#


using System;
using Oracle.ManagedDataAccess.Client;

namespace ODP_Core_Config_API
{
    class odp_core_config
    {
        static void Main(string[] args)
