Question

我对这个json有麻烦：

{
"tester": [
    {
      "type": {
        "ID": "R89d",
        "Description": "Test",
        "lastUpdated": "2016-03-20 20:45:09",
      },
      "specification": {}
    },
    {
      "type": {
        "ID": "RB01",
        "Description": "Another test",
        "lastUpdated": null
      },
      "specification": {
        "0": {
          "ID": "RB01",
          "number": 1,
          "Type": "RB"
        },
        "1": {
          "ID": "RB01",
          "number": 3,
          "Type": "RB"
        }
      }
    },
    {
      "type": {
        "ID": "RT40",
        "Description": "Test 2",
        "lastUpdated": null,
      },
      "specification": {}
    }
  ]
}

特别是当我把它放到json2c#网站时，我得到了这个课程：

public class Type
{
    public string ID { get; set; }
    public string Description { get; set; }
    public string lastUpdated { get; set; }
}

public class __invalid_type__0
{
    public string ID { get; set; }
    public int number { get; set; }
    public string Type { get; set; }
}

public class __invalid_type__1
{
    public string ID { get; set; }
    public int number { get; set; }
    public string Type { get; set; }
}

public class Specification
{
    public __invalid_type__0 __invalid_name__0 { get; set; }
    public __invalid_type__1 __invalid_name__1 { get; set; }
}

public class Tester
{
    public Type type { get; set; }
    public Specification specification { get; set; }
}

public class RootObject
{
    public List<Tester> tester { get; set; }
}

我不知道该网站为何返回invalid type＆＃39;因为json语法是正确的。我的目标是创建一个允许我读取specification的所有属性的类，如何在json中看到有一个对象数组。我需要做的是创建一些允许我以specification的形式访问所有ID - Number - Type对象值的内容。实际上我只用类似这样的东西来管理它：

string responseText = "json above";
var obj = JsonConvert.DeserializeObject<RootObject>(responseText);

foreach(var item in obj.Tester){ //loop through Tester item
    //what I need: 

    foreach(var spec in item.specification){ //not possible 
        spec.Description; ...
    } 
}

Answer 1

问题出在这里：

"specification": {
        "0": {
          "ID": "RB01",
          "number": 1,
          "Type": "RB"
        },
        "1": {
          "ID": "RB01",
          "number": 3,
          "Type": "RB"
        }

在c＃中，名称不能以数字开头。生成器不能命名类型“0”和“1”

修改

如果您可以更改json，请以这种方式修改它：

"specification": [ { "ID": "RB01", "number": 1, "Type": "RB" }, { "ID": "RB01", "number": 3, "Type": "RB" } ]

因此，更改为数组会给出以下结构：

public class Type { public string ID { get; set; } public string Description { get; set; } public string lastUpdated { get; set; } } public class Specification { public string ID { get; set; } public int number { get; set; } public string Type { get; set; } } public class Tester { public Type type { get; set; } public List<Specification> specification { get; set; } } public class RootObject { public List<Tester> tester { get; set; } }

Answer 2

public class Type
{
    public string ID { get; set; }
    public string Description { get; set; }
    public string lastUpdated { get; set; }
}

public class Specification
{
    public string ID { get; set; }
    public int number { get; set; }
    public string Type { get; set; }
}

public class Tester
{
    public Type[] types { get; set; }
    public Specification[] specifications { get; set; }
}

public class RootObject
{
    public List<Tester> tester { get; set; }
}

Answer 3

specification应该是一个数组：

"specification": [
    {
        "ID": "RB01",
        "number": 1,
        "Type": "RB"
    },
    ....
]

和c#实施：

public class Tester
{
    public Type type { get; set; }
    public Specification[] specification { get; set; }
}

或List<Specification>：

public class Tester
{
    public Type type { get; set; }
    public List<Specification> specification { get; set; }
}

和Specification本身：

public class Specification
{
    public string ID { get; set; }
    public int number { get; set; }
    public string Type { get; set; }
}
