winforms - 如何在 CLI/C++ 中生成随机数？

Question

我想制作一个随机数并将其包含在一个整数中......这是我当前的代码

Random RandString = gcnew Random();
             random = (2 * RandString.Next(1 / 2, 100 / 2));
                 if (random >= 1 || random <= 35)
                 {
                     Friend = 1;
                     FriendName = "RainFall";
                 }
                 if (random >= 36 || random <= 65)
                 {
                     Friend = 2;
                     FriendName = "TempoDrop";
                 }
                 if (random >= 66 || random <= 99)
                 {
                     Friend = 3;
                     FriendName = "HeartFelt";
                 }
                 if (random == 100)
                 {
                     Friend = 4;
                     FriendName = "SwagMasta";
                 }

但是每当我尝试这个时，我都会收到这个错误......

我究竟做错了什么？我能做些什么来解决这个问题？

当您使用gcnew运算符时，它会返回一个引用，因此您只需添加^这样的

Random^ RandString = gcnew Random();
