你真的是托管C ++？不是C ++ / CLI？

Do you really mean Managed C++? Not C++/CLI?

您实际上正在使用C ++ / CLI（因为你张贴的错误消息）假设，有两种方法可以做到这一点：

Assuming you're actually using C++/CLI (because of the error message you posted), there are two ways to do this:

array<String^>^ managedArray = gcnew array<String^>(10);

将创建一个管理的阵列，即同一类型在C＃中的String []。

will create a managed array, i.e. the same type as string[] in C#.

gcroot<String^>[] unmanagedArray;

将创建一个非托管C ++阵列（我从来没有实际上阵列尝试这一点 - 它与STL容器的效果很好，所以应该在这里工作，太）

will create an unmanaged C++ array (I've never actually tried this with arrays - it works well with stl containers, so it should work here, too).
