5 .net dll c++-cli loadlibrary
问题1:
有没有办法在运行时显式加载库,而不是在C++/CLI中的编译时.目前我在编译时使用.NET"添加引用".我想明确加载一个托管的DLL.是否有与LoadLibrary等效的.NET?
更新:感谢Randolpho
来自MSDN的 Assembly :: LoadFrom示例
Assembly^ SampleAssembly;
SampleAssembly = Assembly::LoadFrom( "c:\\Sample.Assembly.dll" );
// Obtain a reference to a method known to exist in assembly.
MethodInfo^ Method = SampleAssembly->GetTypes()[ 0 ]->GetMethod( "Method1" );
// Obtain a reference to the parameters collection of the MethodInfo instance.
array<ParameterInfo^>^ Params = Method->GetParameters();
// Display information about method parameters.
// Param = sParam1
// Type = System::String
// Position = 0
// Optional=False
for each ( ParameterInfo^ Param in Params )
{
Console::WriteLine( "Param= {0}", Param->Name );
Console::WriteLine( " Type= {0}", Param->ParameterType );
Console::WriteLine( " Position= {0}", Param->Position );
Console::WriteLine( " Optional= {0}", Param->IsOptional );
}

问题2:
如果Assembly :: LoadFrom是LoadLibrary的.NET等价物.GetProcAddress的等价物是什么?如何为方法创建FunctionPointers?
更新:来自MSDN的 MethodBase.Invoke
using namespace System;
using namespace System::Reflection;
public ref class MagicClass
{
private:
int magicBaseValue;
public:
MagicClass()
{
magicBaseValue = 9;
}
int ItsMagic(int preMagic)
{
return preMagic * magicBaseValue;
}
};
public ref class TestMethodInfo
{
public:
static void Main()
{
// Get the constructor and create an instance of MagicClass
Type^ magicType = Type::GetType("MagicClass");
ConstructorInfo^ magicConstructor = magicType->GetConstructor(Type::EmptyTypes);
Object^ magicClassObject = magicConstructor->Invoke(gcnew array<Object^>(0));
// Get the ItsMagic method and invoke with a parameter value of 100
MethodInfo^ magicMethod = magicType->GetMethod("ItsMagic");
Object^ magicValue = magicMethod->Invoke(magicClassObject, gcnew array<Object^>(1){100});
Console::WriteLine("MethodInfo.Invoke() Example\n");
Console::WriteLine("MagicClass.ItsMagic() returned: {0}", magicValue);
}
};
int main()
{
TestMethodInfo::Main();
}
