TypeLoadException コンストラクタ (String, Exception)

指定したエラー メッセージと、この例外原因である内部例外への参照使用して、TypeLoadException クラス新しインスタンス初期化します。

名前空間: System
アセンブリ: mscorlib (mscorlib.dll 内)
構文構文

解説解説

前の例外直接結果としてスローされる例外については、InnerException プロパティに、前の例外への参照格納されます。InnerException プロパティは、コンストラクタ渡されたものと同じ値を返しますInnerException プロパティによって内部例外値がコンストラクタ渡されなかった場合は、null 参照 (Visual Basic の場合Nothing) を返します

TypeLoadExceptionインスタンス初期プロパティ値を次の表に示します
