我想声明一个handel数组,如下面的代码:
using namespace System::Drawing;
ref class B
{
Bitmap^ b[];
B()
{
b = new Bitmap^[10];
}
};

但是在编译时它会抛出错误
error C2728: 'System::Drawing::Bitmap ^' : a native array cannot contain this managed type
error C4368: cannot define 'b' as a member of managed 'B': mixed types are not supported
error C2728: 'System::Drawing::Bitmap ^' : a native array cannot contain this managed type
error C2440: '=' : cannot convert from 'System::Drawing::Bitmap ^*' to 'System::Drawing::Bitmap ^[]'

有人可以告诉我正确的方式来声明一个handel数组吗?
非常感谢!

你需要使用gcnew 这个.Net数组,而不是C++数组,因为这是一个托管类型的数组,而不是一个本机类型的数组.我没有编译器方便测试此代码,但我相信这将是这样做的方法.
using namespace System::Drawing;
ref class B
{
private:
array<Bitmap^>^ b;
public:
B()
{
b = gcnew array<Bitmap^>(10);
}
};
