我得到了以下Json数据
{
"HasErrors": false,
"Includes": {
"Products": {
"091006": {
"hej" : "tja"
},
"091026": {
"hej" : "tjafsafsa"
}
}
}
}
通过动态JSON,我的意思是Products类上的属性发生了变化,所以我不能在c#类中对它们进行硬编码,就像我使用“HasErrors”一样。
示例:
{
"HasErrors": false,
"Includes": {
"Products": {
"091006": {
"hej" : "tja"
},
"091026": {
"hej" : "tjafsafsa"
}
}
}
}
另一个例子:
{
"HasErrors": false,
"Includes": {
"Products": {
"091126": { //CHANGED
"hej" : "tja"
},
"091043226": { //CHANGED
"hej" : "tjafsafsa"
}
}
}
}
我在.NET中构建了以下类
Response.cs
public class Response<T> where T : new()
{
[JsonProperty("hasErrors")]
public bool HasErrors { get; set; }
[JsonProperty("includes")]
public Includes<T> Includes { get; set; }
}
Includes.cs
public class Includes<T> where T : new()
{
[JsonProperty("products")]
public ProductRoot Products { get; set; }
}
ProductRoot.cs
public class ProductRoot
{
[JsonProperty("products")]
public Dictionary<string, Product> Products { get; set; }
}
Product.cs
public class Product
{
[JsonProperty("hej")]
public string Hej { get; set; }
}
然后我尝试将其反序列化:
var hej = JsonConvert.DeserializeObject<Response<Product>>(json_from_above_as_string);
然后我收到了这个错误:
无法从System.String转换或转换为www.Models.Externals.Product。
[JsonSerializationException:将值“091006”转换为“www.Models.Externals.Product”时出错。路径'Includes.ProductsOrder [0]',第1行,第15173位。]
你们知道我做错了什么吗?
答案 0 :(得分:1)
我成功地实例化了一个<Response<Product>>
类型的对象,并对其进行了序列化以了解引擎盖下发生了什么,作为一个例子,我从中得到的JSON如下:
{
"hasErrors":false,
"includes":{
"products":{
"products":{
"091006":{
"hej":"tja"
}
}
}
}
}
这表明您的JSON根本不与您的对象模型结合。你可以做几件事。将您的JSON格式更改为类似上述内容,或将对象模型更改为以下内容:
public class Response<T> where T : new()
{
[JsonProperty("hasErrors")]
public bool HasErrors { get; set; }
[JsonProperty("includes")]
public Includes<T> Includes { get; set; }
}
public class Includes<T> where T : new()
{
[JsonProperty("products")]
public Dictionary<string, T> Products { get; set; }
}
public class Product
{
[JsonProperty("hej")]
public string Hej { get; set; }
}

我通过删除ProductRoot类解决了这个问题。
现在看起来像这样:
public class Response<T> where T : new()
{
[JsonProperty("hasErrors")]
public bool HasErrors { get; set; }
[JsonProperty("includes")]
public Includes<T> Includes { get; set; }
}
public class Includes<T> where T : new()
{
[JsonProperty("products")]
public Dictionary<string, Product>Products { get; set; }
}
