 static property System::Security::Principal::IPrincipal ^ CurrentPrincipal { System::Security::Principal::IPrincipal ^ get(); void set(System::Security::Principal::IPrincipal ^ value); };

public static System.Security.Principal.IPrincipal? CurrentPrincipal { get; set; }

static member CurrentPrincipal : System.Security.Principal.IPrincipal with get, set

Public Shared Property CurrentPrincipal As IPrincipal

プロパティ値

IPrincipal

セキュリティ コンテキストを表す IPrincipal 値。

例外

SecurityException

呼び出し元に、プリンシパルを設定するために必要なアクセス許可がありません。
