Arrays of strings in Managed C++

I'm trying to write an application in Managed C++, but I cannot work out how to declare an array of strings.

String^ linet[];

throws an error

'System::String ^' : a native array cannot contain this managed type

So I suppose there's a different way to do this for managed data types. What exactly is it?

Solution

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

    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);

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

    gcroot<String^>[] unmanagedArray;

    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).
