使用DataContractJsonSerializer作为JSON数组序列化对象

Question

我有一个包含项目列表的类。 我想使用DataContractJsonSerializer作为json数组将此类的实例序列化为json。 例如。

class MyClass 
{
    List<MyItem> _items;
}

class MyItem
{
   public string Name {get;set;}
   public string Description {get;set;}
}

当序列化为json时，应该像这样：

[{"Name":"one","Description":"desc1"},{"Name":"two","Description":"desc2"}]

Answer 1

[DataContract]
public class MyItem
{
    [DataMember]
    public string Name { get; set; }

    [DataMember]
    public string Description { get; set; }
}

class Program
{
    static void Main()
    {
        var graph = new List<MyItem>
        {
            new MyItem { Name = "one", Description = "desc1" },
            new MyItem { Name = "two", Description = "desc2" }
        };
        var serializer = new DataContractJsonSerializer(graph.GetType());
        serializer.WriteObject(Console.OpenStandardOutput(), graph);
    }
}
