C# 反序列化包含RootObject的c类结构

我有一个JSON API结果，我通过一个在线JSON-to-C结构程序来处理它，以创建类结构。我已经在其他项目中使用过很多次了。JSON返回所有内容以及一个公共类RootObject，该对象引用返回值的状态和有效负载段

我正在使用ASP.NET C库使用JavaScriptSerializer反序列化结果JSON：

我尝试使用类结构解析的完整JSON结果是：

  "status": {
    "statusCode": 0,
    "errorType": 0,
    "errorCode": 0,
    "errorMessage": "Success with response body"

              }
            }
          },
          {

              }
            }
          }
        ],
        "supportedApp": {

            "imageSize": {
              "length": "100",
              "width": "100",
              "uom": 0
            }
          }
        },
        "supportAdditionalDriver": 0,
        "customerType": 0,
        "vehicleKey": "937db044-8328-4188-a3d2-68ac3b183752"
      }
    ]
  }
}

我通过json2csharp.com运行这个程序来获得结构。上面的示例只是一个缩写的“测试”

反序列化程序返回错误：以有效负载开头的JSON基元无效

我看到了使用RootObject但使用Newtonsoft JSON库的示例。我想使用微软图书馆。我真的需要切换到Newtonsoft JSON吗？如果我可以使用JavaScriptSerializer库，如何使用？

与您发布的JSON相对应的类是：

public class RootObject
{
    public Status status { get; set; }
    public Payload payload { get; set; }
}

public class Status
{
    public int statusCode { get; set; }
    public int errorType { get; set; }
    public int errorCode { get; set; }
    public string errorMessage { get; set; }
}

public class Payload
{
    public List<VehicleSummary> vehicleSummary { get; set; }
}

public class VehicleSummary
{
    public string vin { get; set; }
    public string vehicleIdentifier { get; set; }
    public string modelName { get; set; }
    public string modelYear { get; set; }
    public string nickName { get; set; }
    public int generation { get; set; }
    public string extColorCode { get; set; }
    public string trim { get; set; }
    public Image imagePath { get; set; }
    public int enrollmentStatus { get; set; }
    public int fatcAvailable { get; set; }
    public int telematicsUnit { get; set; }
    public int fuelType { get; set; }
    public string colorName { get; set; }
    public int activationType { get; set; }
    public string mileage { get; set; }
    public string dealerCode { get; set; }
    public List<MobileStore> mobileStore { get; set; }
    public SupportedApp supportedApp { get; set; }
    public int supportAdditionalDriver { get; set; }
    public int customerType { get; set; }
    public string vehicleKey { get; set; }
}

public class Image
{
    public string imageName { get; set; }
    public string imagePath { get; set; }
    public string imageType { get; set; }
    public ImageSize imageSize { get; set; }
}

public class ImageSize
{
    public string length { get; set; }
    public string width { get; set; }
    public int uom { get; set; }
}

public class MobileStore
{
    public int osType { get; set; }
    public string downloadURL { get; set; }
    public Image image { get; set; }
}

public class SupportedApp
{
    public string appType { get; set; }
    public Image appImage { get; set; }
}

其中result是您在问题中发布的JSON字符串

但是，请注意，如果您将类放在另一个名为TestStruct的类中，则需要将其考虑在内，并反序列化为TestStruct.RootObject，例如：

var root = new JavaScriptSerializer().Deserialize<TestStruct.RootObject>(result);

获得反序列化对象后，可以从中提取一些有趣的信息，如下所示：

var root = new JavaScriptSerializer().Deserialize<RootObject>(result);

foreach (var vs in root.payload.vehicleSummary)
{
    Console.WriteLine(string.Format("{0} - {1} {2} {3}, {4} mi", 
        vs.vin, vs.colorName, vs.modelYear, vs.modelName, vs.mileage));
}

下面是一个使用Json.Net的工作演示：

您可以向我们展示您试图反序列化到这些类中的Json吗？完整的响应是：Oops。太长，无法粘贴到这里。我现在使用的是Newtonsoft json。仍然无法正常工作。正在使用JsonConvert。我看到了使用RootObject的示例，但我没有这个库。Net.Framework 4.5 Visual Studio 2017谢谢Brian。这就是我所认为的解决办法。然而，在我的ASP.NET 4.5项目中，我无法让RootObject显示为有效！智能感知没有显示出来。我已经使用了Newtonsoft.Json；在页面中。然而，在我剪切并粘贴了您提供的示例之后，RootObject现在以intellisense显示，并且是有效的。这似乎是Visual Studio中的一个bug！！！！

var root = new JavaScriptSerializer().Deserialize<TestStruct.RootObject>(result);

var root = JsonConvert.DeserializeObject<RootObject>(result);

foreach (var vs in root.payload.vehicleSummary)
{
    Console.WriteLine(string.Format("{0} - {1} {2} {3}, {4} mi", 
        vs.vin, vs.colorName, vs.modelYear, vs.modelName, vs.mileage));
}
