c# - 将 json 对象数组发送到 .net Web 服务

Question

我有这样的 JSON:
编辑:JSON 是错误的。我是手写的

var VehiclesData = {
    "VehiclesData": {
        "VehiclesList": [
            { "year": "2010", "make": "honda", "model": "civic" },
          { "year": "2011", "make": "toyota", "model": "corolla" },
          { "year": "2012", "make": "audi", "model": "a4" }]
    }
}

我正在尝试将其发送到 .net Web 服务 API，如下所示:

[WebMethod]
[ScriptMethod(UseHttpGet = false, ResponseFormat = ResponseFormat.Json)]
public string ProcessData(VehiclesData VehiclesData)
{
    //...Do stuff here with VehiclesData
}

public class VehiclesData
{
    public List<Vehicle> VehiclesList = new List<Vehicle>();

    public class Vehicle
    {
        private string year = string.Empty;
        private string make = string.Empty;
        private string model = string.Empty;

        public string Year { get { return this.year; } set { this.make = value; } }
        public string Make { get { return this.make; } set { this.make = value; } }
        public string Model { get { return this.model; } set { this.model = value; } }
     }
}

我收到“对象与目标类型不匹配”。

对于平面 JSON 对象，我可以很好地获取数据，但是对于对象数组和 C# 列表，我有点迷失。

要按原样工作，我认为您的 JSON 对象需要如下所示: 即:

 var VehiclesData = {
    "VehiclesList": 
      [
        { "Year": "2010", "Make": "honda", "Model": "civic" },
        { "Year": "2011", "Make": "toyota", "Model": "corolla" },
        { "Year": "2012", "Make": "audi", "Model": "a4" }
      ]
    };

或者，您应该能够使用一些属性来提供帮助。

[DataContract]
public class VehiclesData
{
  [DataMember(Name = "year")]
  public string Year { get; set; }
  .
  .
  .
}

这将允许您在 JSON 对象中保留小写名称，但您仍然需要删除“VehiclesData”:{ 部分，因为我认为在序列化过程中 .NET 会假定这是一个属性。
