EnvironmentPermission.AddPathList(EnvironmentPermissionAccess, String) メソッド

定義

指定した環境変数へのアクセス権を既存のアクセス許可の状態に設定します。

public:
 void AddPathList(System::Security::Permissions::EnvironmentPermissionAccess flag, System::String ^ pathList);
public void AddPathList (System.Security.Permissions.EnvironmentPermissionAccess flag, string pathList);
member this.AddPathList : System.Security.Permissions.EnvironmentPermissionAccess * string -> unit
Public Sub AddPathList (flag As EnvironmentPermissionAccess, pathList As String)

パラメーター

flag
EnvironmentPermissionAccess

EnvironmentPermissionAccess 値のいずれか 1 つ。

pathList
String

環境変数の一覧 (セミコロン区切り)。

例外

pathList パラメーターが null です。

flag パラメーターが EnvironmentPermissionAccess の正しい値ではありません。

次のコード例は、 メソッドの使用方法を AddPathList 示しています。
