如何动态访问Grid中的成员的属性？（C++）

Question

例如，我在grid中添加了一个文本框，然后使用

grid->Children->GetAt(0);

但是我无法通过返回的东西得到文本框里的文本（即Text属性），有没有方法可以获得？

Answer 1

当然可以啊~

你可以使用下面的代码：

	TextBox^ txb = static_cast<TextBox^>(grid->Children->GetAt(0));
	auto text = txb->Text;

如果类型错误，如何判断并纠正异常？

Answer 4

已经成功，代码：

auto Child = grid->Children->GetAt(i);
auto Childtype = Child->GetType();
auto UCtype = ref new Type(ref new 类名());
if (Childtype->ToString() == UCtype->ToString()){
	auto UC = static_cast<Page7UserControl1^>(grid->Children->GetAt(i));
}
