c# - 如何在没有变量的情况下将新对象添加到列表中？

Question

我试图通过构建一个新的 asd 然后添加它来将我的 asd 类的一个新实例添加到列表中，但是 Unity 给出了一个 Object not set to instance of object 错误。

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class asd {
    public int a = 0;
    public string s = "asd";

    public asd (int apop, string ssdf) {
        a = apop;
        s = ssdf;
    }
}

public class test : MonoBehaviour {

    public List<asd> list;

    // Use this for initialization
    void Start () {
        list.Add (new asd(1, "yeee"));
        list.Add (new asd(456, "oooo"));
    }

    // Update is called once per frame
    void Update () {

    }
}

Answer 1

如下所示正确实例化您的列表，然后向其添加 asd

public List<asd> list = new List<asd>();

// Use this for initialization
void Start () {
      list.Add(new asd(1, "yeee"));
      list.Add(new asd(456, "oooo"));
    }
