将字符串数组从WWW转换为Unity3d中的类列表

Question

我在将WWW字符串数组转换为类列表时遇到了一些麻烦。我想要做的是实例化一个预制件，其中包含许多文本元素。这是基类

public class VehicleIndex : MonoBehaviour 
{
    public string ID{ get; set;}
    public string Make{ get; set;}
    public string Model{ get; set;}
    public string Year{ get; set;}
    public string Mileage{ get; set;}


    public VehicleIndex(string id, string make, string model, string year, string mileage)
    {
        this.ID = id;
        this.Make = make;
        this.Model = model;
        this.Year = year;
        this.Mileage = mileage;
    }



}

这是从Mysql数据库获取WWW数据的函数

    public List<VehicleIndex> VehicleIndexList = new List<VehicleIndex> ();
    public string[] VehicleStringArray;

    public IEnumerator GetAllVehicles()
    {
        WWW VehicleData = new WWW ("http://localhost/CMVM/LoadVehicle.php"); 
        yield return VehicleData;

        Debug.Log (VehicleData.text);
        string TheVehicleData = VehicleData.text;
                              The information comes back just fine.     
        if(TheVehicleData[TheVehicleData.Length - 1] == '/')
        { 
        TheVehicleData.TrimEnd('/');      Here I'm removing the delimiter
        }
        string[] results = TheVehicleData.Split(new char[] { '/' }, StringSplitOptions.RemoveEmptyEntries);
      for (int i = 0; i < results.Length; i++) 
       {
        Debug.Log (results[i]);
       }
        VehicleStringArray = results; The results go back into an array

        VehicleIndexList = VehicleStringArray.Select(sArr => new VehicleIndex 
        {
            ID=VehicleStringArray[0],
            Make=VehicleStringArray[1],
            Model=VehicleStringArray[2],
            Year=VehicleStringArray[3],
            Mileage=VehicleStringArray[4]
        }).ToList();


    }

它看起来应该只有它给出错误：类型VehicleIndex' does not contain a constructor that takes0'参数我缺少什么？我需要在课堂上添加一些东西吗？一个列表？数组？谢谢您的帮助！对此，我真的非常感激。

附加 - 添加了对象初始值设定项

public VehicleIndex Vi;

然后将lambda表达式更改为

VehicleIndexList = VehicleStringArray.Select(sArr => new VehicleIndex 
    {
        Vi.ID==VehicleStringArray[0],
        Vi.Make==VehicleStringArray[1],
        Vi.Model==VehicleStringArray[2],
        Vi.Year==VehicleStringArray[3],
        Vi.Mileage==VehicleStringArray[4]
    }).ToList();

避免红线的唯一方法是使用双倍相等。我不确定这是否正确，因为它仍然不起作用，我猜不是。

Answer 1

你有一个构造函数，它将所有属性作为参数;只需使用它而不是对象初始值设定项：

    VehicleIndexList = VehicleStringArray.Select(sArr => new VehicleIndex 
    (
        VehicleStringArray[0],
        VehicleStringArray[1],
        VehicleStringArray[2],
        VehicleStringArray[3],
        VehicleStringArray[4]
    )).ToList();

但请注意，构造函数通常只需要对象正常运行所需的参数。如果不需要属性值，则删除构造函数并使用初始化语法（new VehicleIndex { }）没有任何问题。

这与JavaScript的join（）基本相同

String.Join Method
