在C#中解析JSON数组 [英] Parse JSON array in C#

问题描述

我正在尝试解析以下json数组

I'm trying to parse the following json array

[
    {
        "email": "[e-mail]",
        "timestamp": 1337197600,
        "smtp-id": "<[e-mail]>",
        "event": "processed"
    },
    {
        "email": "[e-mail]",
        "timestamp": 1337966815,
        "smtp-id": "<[e-mail]>",
        "category": "newuser",
        "event": "clicked"
    },
    {
        "email": "[e-mail]",
        "timestamp": 1337969592,
        "smtp-id": "<[e-mail]>",
        "event": "processed"
    }
]

我以前并没有真正使用过json格式，所以它有点新.我发现我可以轻松解析单个元素，即

I've not really used json format before, so it's all a little new. I found I can parse a single element easily, i.e.

{
        "email": "[e-mail]",
        "timestamp": 1337197600,
        "smtp-id": "<[e-mail]>",
        "event": "processed"
}

dynamic stuff = JsonConvert.DeserializeObject(json);
Response.Write(string.Format("{0} = {1}<br />", "timestamp", stuff.timestamp)); 
//etc

但是我在如何将单个元素放入数组以循环遍历中苦苦挣扎.

But i'm struggling with how to get the individual elements into an array to loop through.

我虽然打算分裂}，{但运气并不好.我想我有一种更简单的方式会丢失.

I though about splitting the sting on },{ but didn't have much luck with that. I imagine there's an easier way i'm missing.

谢谢.

推荐答案

您可以创建一个像这样的类，以接受json字符串中的所有属性:

You can create a class like this one, to accept all properties from the json string:

public class MyClass
{
    public string email { get; set; }

    public long timestamp { get; set; }

    [JsonProperty("smtp-id")]
    public string smtpid { get; set; }

    public string category { get; set; }

    [JsonProperty("event")]
    public string evt { get; set; }
}

您可能会注意到smtpid和evt属性上有JsonProperty属性，因为您不能将json字符串中的名称用作C#中的属性.

As you can notice there is JsonProperty attribute on the smtpid and evt properties, because you can not use the names in the json string as properties in C#.

然后只需调用以下行:

var list = JsonConvert.DeserializeObject<List<MyClass>>(json);

，您将获得与json字符串匹配的对象的强类型列表.

and you'll get a strongly typed list of objects that matches the json string.
