推荐答案

您不必使用DataContractJsonSerializer来解析"一个json字符串，但是您可以使用它反序列化为一个对象或对象列表.如果您要这样做，这是一种将其反序列化为对象列表的简单方法.

You wouldn't necessarily "parse" a json string using DataContractJsonSerializer, but you can deserialize it into an object or list of objects using this. Here is a simple way to deserialize it to a list of objects if this is what you're after.

首先，您需要计划反序列化的对象类型为:

First you need to have an object type you plan on deserializing to:

[DataContract]
public class MyElement
{
    [DataMember(Name="elementsProperties")] // this must match the json property name
    public string ElementsProperties { get; set; }
}

然后您可以使用类似以下方法的方法将json字符串反序列化为对象列表

You can then use something like the following method to deserialize your json string to a list of objects

private List<MyElement> ReadToObject(string json)
{
    var deserializedElements = new List<MyElement>();
    using(var ms = new MemoryStream(Encoding.UTF8.GetBytes(json)))
    {
        var ser = new DataContractJsonSerializer(deserializedElements.GetType());
        deserializedElements = ser.ReadObject(ms) as List<MyElement>;
    }
    return deserializedUsers;
}
