我想創建一個自定義屬性,允許我的每個自定義控件庫中的方法在運行時初始化。我設法得到這個使用反射如下工作:C++/CLI屬性
InitOnload::initialise()
{
// get a list of types which are marked with the InitOnLoad attribute
array<System::Reflection::Assembly^>^ assemblies = System::AppDomain::CurrentDomain->GetAssemblies();
for each(System::Reflection::Assembly^ assembly in assemblies)
{
try
{
System::Type^ type = System::Type::GetType("INITONLOAD.InitOnload");
array<Object^>^ attributes = assembly->GetCustomAttributes(type, false);
if(attributes->Length > 0)
{
auto field =
type->GetFields(
System::Reflection::BindingFlags::Static |
System::Reflection::BindingFlags::Public |
System::Reflection::BindingFlags::NonPublic);
}
}
catch (...)
{
}
}
}
foo2的被啓動時初始化,但只有當它在相同的命名空間如上InitOnload定義。
[assembly: InitOnload()];
public ref class foo2 : public System::Attribute
{
public:
foo2()
{
};
};
如果我嘗試在不同的自定義控制庫不initilaise foo2的下方initilaise方法不initilalise:
[assembly: INITONLOAD::InitOnload()];
public ref class foo : public System::Attribute
{
public:
foo()
{
};
};
任何想法?
有人將不得不首先加載程序集。 – 2012-03-10 17:53:26
