接收到的数据是这样的:

在每个项目中,都有一个对象,customer,我有一个相同的类。如何使用 Json.net 转换它们?

我尝试了以下方法:

var data = JsonConvert.DeserializeObject<List<customer>>(val);

并添加另一个类:

public class customerJson
{
public Customer customer{ get; set; }
}

并尝试反序列化它:

var data = JsonConvert.DeserializeObject<List<customerJson>>(val);

对于他们两个我都有一个异常(exception):

Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[customer]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly. To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object. Path 'rows', line 1, position 8.

数据:

{"rows":[{"id":"232333","name":"nam"},{"id":"3434444","name":"2ndName"}]}

最佳答案

如果我正确阅读了你的 json 数据结构,你会想要这样:

public class Root
{
public List<Customer> rows { get; set; }
}

var data = JsonConvert.DeserializeObject<Root>(val);

测试代码:

void Main()
{
var test = JsonConvert.DeserializeObject<Root>("{\"rows\":[{\"id\":\"232333\",\"name\":\"nam\"},{\"id\":\"3434444\",\"name\":\"2ndName\"}]}");

Console.WriteLine(test.rows[0].id); // prints 232333
}

public class Customer
{
public int id { get; set; }
}

public class Root
{
public List<Customer> rows { get; set; }
}
