我在Microsoft Visual Studio中创建了空C ++ / CLI表单。
我想要做的是将汽车品牌保留在一个阵列中，将车型保留在其他阵列中。 然后我将绘制一个品牌，将其贴上标签，一个来自该品牌的车型和另外三个来自其他品牌的车型。
在我的表单中，我想创建2个数组：
String brands[7]={"Mercedes","Opel","Toyota","Fiat","Audi","Renault","Volkswagen"};
String models[7][5]={{"Benz","Vito","AMG","Klasa A","Klasa E"},
{"Astra","Corsa","Insignia","Zafira","Mokka"},
{"Avensis","Corolla","Yaris","Auris","RAV4"},
{"126p","Panda","Punto","500","Tipo"},
{"A4","A6","Q7","R8","A7"},
{"Megane","Captur","Scenic","Kadjar","Espace"},
{"Golf","Passat","Tiguan","Beetle","Touran"}};
我无法将它放在我的MyForm.h文件中，我收到E2022错误。 你建议我用什么简单的解决方案？

答案 0 :(得分：0)
以下是这样做的方法：
首先在受保护的部分声明您的数组（就像您在那里一样）。
array<String^>^ marki;
array<String^,2>^ modele; //Note the declration 2 next to String^. It is rank of the array. 2 for two dimensional.
在构造函数（MyForm()）中初始化数组，如下所示。
//SINGLE DIMENSION ARRAY
marki = gcnew array<String^> {"Mercedes","Opel","Toyota","Fiat","Audi","Renault","Volkswagen"};
//MULTI DIMENSIONAL ARRAY
modele = gcnew array<String^,2> {{"Benz","Vito","AMG","Klasa A","Klasa E"},
{"Astra","Corsa","Insignia","Zafira","Mokka"},
{"Avensis","Corolla","Yaris","Auris","RAV4"},
{"126p","Panda","Punto","500","Tipo"},
{"A4","A6","Q7","R8","A7"},
{"Megane","Captur","Scenic","Kadjar","Espace"},
{"Golf","Passat","Tiguan","Beetle","Touran"}};
}
测试：
String^ test = modele[2,4]; //RAV4
