注釈

クライアント アプリケーションでは、すべてのユーザーに適用されるグローバル構成、個々のユーザーに適用される個別の構成、ローミング ユーザーに適用される構成が使用されます。 パラメーターは userLevel 、ユーザー レベルがない (構成ファイルがアプリケーションと同じディレクトリにある) か、ユーザーごとのレベル (構成ファイルがユーザー レベルによって決定されるアプリケーション設定パス内にある) かを示すことによって、開く構成ファイルの場所を決定します。

に対して次のいずれかの値を渡して、取得する構成を指定します userLevel。

• すべてのユーザーに Configuration 適用される オブジェクトを取得するには、 を に設定 userLevel します None。

• 現在のユーザーに適用されるローカル Configuration オブジェクトを取得するには、 を にPerUserRoamingAndLocal設定userLevelします。

• 現在のユーザーに適用されるローミング Configuration オブジェクトを取得するには、 を にPerUserRoaming設定userLevelします。

  注意

  リソースの オブジェクトを Configuration 取得するには、設定を継承するすべての構成ファイルに対する読み取りアクセス許可がコードに必要です。 構成ファイルを更新するには、構成ファイルとそれが存在するディレクトリの両方に対する書き込みアクセス許可をコードに追加する必要があります。
