範例

以下程式碼範例說明如何將 套 AssemblyFlagsAttribute 用到 assembly 中，以及如何在執行時讀取旗標。 範例同時建立了屬性的實例，並利用該 AssemblyFlags 屬性來顯示旗標。 關於如何將 應用AssemblyFlagsAttribute於動態裝配的範例，請參見屬性。AssemblyName.Flags

備註

列 AssemblyNameFlags 舉描述了可利用此屬性設定的組裝特性。

要存取已指定的組件旗標，先使用該 Assembly.GetName() 屬性取得 AssemblyName 物件，再用該 AssemblyName.Flags 屬性取得 AssemblyNameFlags 值。

要指定AssemblyNameFlags動態組裝的旗標，先設定AssemblyName.Flags你傳遞給AppDomain.DefineDynamicAssembly方法的物件屬性AssemblyName。
