我正在尝试在Visual Basic中将一个特殊数组反序列化为对象。以下json数据由我使用的Web服务提供；我感兴趣的部分是"数据"属性；基本上它是一个字符串数组的数组，每个数组代表一个对象：
{"timestamp":1385984969075,
"data":
[
[1590,null,null,null,0],
[1020,"data a",null,null,0],
[1025,"data b",null,null,0],
...
[2756,"data c",null,
[
{"id":2,"name":"Tom","mail":"tom@test.te","f_id":6,"md":1},
{"id":3,"name":"Carl","mail":"carl@test.te","f_id":6,"md":1}
]
,3],
[1277,"data d",null,null,0],
...
]}
在本例中，每个数组的数据项4可以为null，也可以包含对象数组。
我想将数组反序列化为对象列表，但我无法使其工作。我搜索了很多类似的帖子，但到目前为止，我找不到任何有用的东西。
（我用Visual Basic.net编写，但欢迎使用C#示例。）
有人能帮忙吗？
更新：
这里是另一个使用对象数组来映射您所拥有的数组的例子。然后，我提取了数组中的每一条数据。
再次希望这将帮助你：
var list = new People
{
PersonList = new object[]
{
new object[]
{
"Test1", "Test2", "Test3", null, new object[]{new Person{Name="John", Age=21}}, 1
},
new object[]
{
"Test4", "Test5", "Test6", null, null, 2
},
new object[]
{
"Test17", "Test8", "Test9", null, new object[]{new Person{Name="Sara", Age=31}}, 3
},
new object[]
{
"Test10", "Test11", "Test12", null, null, 4
},
new object[]
{
"Test13", "Test14", "Test15", null, new object[]{new Person{Name="John", Age=31}}, 5
}
}
};
string output = JsonConvert.SerializeObject(list);
var objList = JsonConvert.DeserializeObject<People>(output);
objectList = objList.PersonList;
foreach(JArray objectItem in objectList)
{
var stringOne = (string)objectItem[0];
var stringTwo = (string)objectItem[1];
var stringthree = (string)objectItem[2];
var nullObj = objectItem[3];
foreach(var individual in objectItem[4])
{
JObject obj = (JObject)JToken.FromObject(individual);
var person = obj.ToObject<Person>();
string name = person.Name;
int age = person.Age;
}
var num = (int)objectItem[5];
}
JSON:
{
"PersonList": [
[
"Test1",
"Test2",
"Test3",
null,
[
{
"Name": "John",
"Age": 21
},
{
"Name": "Pete",
"Age": 44
}
],
1
],
[
"Test4",
"Test5",
"Test6",
null,
null,
2
],
[
"Test17",
"Test8",
"Test9",
null,
[
{
"Name": "Sara",
"Age": 31
}
],
3
],
[
"Test10",
"Test11",
"Test12",
null,
null,
4
],
[
"Test13",
"Test14",
"Test15",
null,
[
{
"Name": "John",
"Age": 31
}
],
5
]
]
}
人员类别：
public class Person
{
public string Name { set; get; }
public int Age { set; get; }
}
PeopleList类：
public class People
{
public object[] PersonList { set; get; }
}
再次感谢您的努力！我已经将您的示例代码翻译成VB.NET（请注意，定义了"list"对象的第一个块必须是Visual Studio中的一行；我刚刚对其进行了格式化，以便更好地进行概述）：
Dim list = New People With {.PersonList =
New Object() {
New Object() {"Test1", "Test2", "Test3", Nothing, New Object()
{New Person With {.Name = "John", .Age = 21}},
1},
New Object() {"Test4", "Test5", "Test6", Nothing, Nothing, 2},
New Object() {"Test17", "Test8", "Test9", Nothing, New Object()
{New Person With {.Name = "Sara", .Age = 31}},
3},
New Object() {"Test10", "Test11", "Test12", Nothing, Nothing, 4},
New Object() {"Test13", "Test14", "Test15", Nothing, New Object()
{New Person With {.Name = "John", .Age = 31}},
5}
}
}
Dim output As String = JsonConvert.SerializeObject(list)
MessageBox.Show(output)
Dim objList = JsonConvert.DeserializeObject(Of People)(output)
Dim objectList As Object() = objList.PersonList
For Each objectItem As JArray In objectList
Dim stringOne As String = CStr(objectItem(0))
Dim stringTwo As String = CStr(objectItem(1))
Dim stringThree As String = CStr(objectItem(2))
Dim nullObj As Object = objectItem(3)
For Each individual As Object In objectItem(4)
Dim obj As JObject = DirectCast(JToken.FromObject(individual), JObject)
Dim person As Person = obj.ToObject(Of Person)()
Dim name As String = person.Name
Dim age As Integer = person.Age
Next
Dim num As Integer = CInt(objectItem(5))
Next
基本上，这种方法就是我现在要做的。我只是觉得必须有一种更优雅的方式（无意冒犯！）使用JSON.NET。在我看来，最大的缺点是for每个循环中的类型转换列表；我的数据对象有大约110个属性，其中两个具有子对象，每个子对象有10个属性。此外，在我的项目中还有3或4个其他数据对象的大小是最小的。
因此，我的想法是编写一个函数，从目标对象派生属性类型，然后或多或少地自动进行类型转换。我有一个web服务调用的属性名称列表，因此此列表可用于查找与响应项相对应的属性名称。
无论如何，我会看看jArray和jObject，因为到目前为止我还没有使用过它们。
