如何以可以从 C# 中的其他方法访问的方式存储随机类变量？

凯克·桑托斯

我需要获取一个随机类，存储到一个“全局类”变量中（这样我就可以用其他方法访问它），但我找不到任何好的方法来做到这一点，我一直在尝试做的是使用对象变量...我从 python 到 C#，所以对象变量的属性对我来说看起来有点神秘...我一直在寻找如何使它工作，但我找不到合适的方法来做它没有一堆if语句......

//There might not be all the necessary namespaces to run this code
using UnityEngine; //where the random.range() came from

public class man1 //Initialization of the first class
{
    public int val = 1;
}

public class man2 //Initialization of the second class
{
    public int val = 2;
}

public class man3 //Initialization of the third class
{
    public int val = 3;
}

public class allMan
{ //Where all classes 'merge'

    private object chosenMan; //Where the chosen it's going to be stored

    public allMan() //Constructor
    {
        //Have all man in one array to easily get the chosen from index
        object[] men = new object[] { new man1(), new man2(), new man3() }; 
        var choice = Random.range(0, men.Length); //Randomly get the index
        chosenMan = men[choice]; // Atribute the chosen class
    }
    public void doActionWithChoosedMan()
    {
        Console.WriteLine(chosenMan.val); //ERROR
    }
}

我应该如何解决这个问题？谢谢。

编译器将一个变量类型化为对象，并且所有实例成员都将被编译器验证为有效。另一个变量类型为动态，所有实例成员将被编译器忽略并在执行时由 DLR 调用。

您可以使用dynamic代替object

 public class allMan
   { 
    //Where all classes 'merge'

    private dynamic chosenMan; //Where the chosen it's going to be stored

    public allMan() //Constructor
    {
        //Have all man in one array to easily get the chosen from index
        object[] men = new object[] { new man1(), new man2(), new man3() };
        var choice = Random.range(0, men.Length); //Randomly get the index
        chosenMan = men[choice]; // Atribute the chosen class
    }
    public void doActionWithChoosedMan()
    {
        Console.WriteLine(chosenMan.val); //ERROR
    }
}
