Managed C ++中的字符串数组 [英] Arrays of strings in Managed C++
问题描述
我试图在Managed C ++中编写一个应用程序,但我无法确定如何声明一个字符串数组。 String ^ linet [];
引发错误
'System :: String ^':本机数组不能包含此托管类型
为托管数据类型执行此操作。
你真的是指Managed C ++吗?不是C ++ / CLI?
假设你实际上使用C ++ / CLI(因为你发布的错误信息),有两种方法:
array< String ^> ^ managedArray = gcnew array< String ^>(10)
将创建一个托管数组,即与C#中的string []类型相同。
gcroot< String ^> [] unmanagedArray;
将创建一个非托管C ++数组(我从来没有实际尝试过数组 - stl容器,所以它也应该在这里工作)。
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?
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).
