AssemblyBuilder.SetCustomAttribute メソッド

このアセンブリのカスタム属性を設定します。

オーバーロードの一覧

カスタム属性ビルダを使用して、このアセンブリのカスタム属性を設定します。

[Visual Basic] Overloads Public Sub SetCustomAttribute(CustomAttributeBuilder)

[C#] public void SetCustomAttribute(CustomAttributeBuilder);

[C++] public: void SetCustomAttribute(CustomAttributeBuilder*);

[JScript] public function SetCustomAttribute(CustomAttributeBuilder);

指定したカスタム属性 BLOB を使用して、このアセンブリのカスタム属性を設定します。

[Visual Basic] Overloads Public Sub SetCustomAttribute(ConstructorInfo, Byte())

[C#] public void SetCustomAttribute(ConstructorInfo, byte[]);

[C++] public: void SetCustomAttribute(ConstructorInfo*, unsigned char __gc[]);

[JScript] public function SetCustomAttribute(ConstructorInfo, Byte[]);

使用例

[Visual Basic, C#, C++] 次のコード例は、 SetCustomAttribute を使用して、動的に生成するアセンブリにカスタム属性を結び付ける方法を示しています。

[Visual Basic, C#, C++] メモ   ここでは、SetCustomAttribute のオーバーロード形式のうちの 1 つだけについて、使用例を示します。その他の例については、各オーバーロード形式のトピックを参照してください。
