範例

下列範例會嘗試從 mscorlib 元件載入不存在的類型。 會攔截產生的例外狀況，並 TypeName 顯示 和 Message 值。 若要執行此程式碼範例，您必須提供完整的元件名稱。 如需如何取得完整元件名稱的資訊，請參閱 元件名稱。

// Load the mscorlib assembly and get a reference to it.
// You must supply the fully qualified assembly name for mscorlib.dll here.

給繼承者的注意事項

在 TypeName 衍生類別中覆寫時，請務必呼叫基類的 TypeName 屬性。

這個屬性是唯讀的。
