xml to json （asp.net）

[qqzeng-ip]

xml数据：
http://rainmeter.accu-weather.com/widget/rainmeter/weather-data.asp?location=ASI|CN|CH007|YULIN&metric=c

如何获取如下json数据：


asp.net 如何取得如下：

{
"city":"Yulin",
"curr_temp":72,
"curr_text":"Mostly Sunny",
"curr_icon":2,

"forecast":[{
"day_date":"3\/6\/2010",
"day_text":"Sunny and very warm",
"day_icon":1,
"day_htemp":87,
"day_ltemp":65
},
{"day_date":"3\/7\/2010",
"day_text":"Not as warm with low clouds",
"day_icon":8,
"day_htemp":69,
"day_ltemp":60},

{"day_date":"3\/8\/2010",
"day_text":"Cloudy with spotty showers",
"day_icon":12,
"day_htemp":69,
"day_ltemp":48},

{"day_date":"3\/9\/2010",
"day_text":"Breezy and colder withrain",
"day_icon":18,
"day_htemp":53,
"day_ltemp":43},

{"day_date":"3\/10\/2010",
"day_text":"Sunny and warmer",
"day_icon":1,
"day_htemp":59,
"day_ltemp":51}

如何遍历xml里面 forecast 里面

$day = count($xml->forecast->day);
for ($i = 0; $i < $day; $i++) {
->forecast->day[$i]->obsdate;
->forecast->day[$i]->daytime->txtshort;
->forecast->day[$i]->daytime->weathericon;
->forecast->day[$i]->daytime->hightemperature;
->forecast->day[$i]->daytime->lowtemperature;
}

用c# 怎么来呢

xml 高 手 呢

[MicroDeviser]

我不是高手，帮你顶~~~~~~~

不够分再加 有的是分...

[以专业开发人员为伍]

.net framework中分别拥有xml和json的序列化框架类。

[qqzeng-ip]

我可以序列化出来 但是获取想要的部分数据 有没有快捷的办法 ？ 我看php就是七八行代码就搞掂了

[cpp2017]

你只要哪部分数据？做个条件筛选就可以了。

[qqzeng-ip]

$weather['city'] = (string)$xml->local->city;//城市
$weather['curr_temp'] = (int)$xml->currentconditions->temperature;//气温
$weather['curr_text'] = (string)$xml->currentconditions->weathertext;//天气
$weather['curr_icon'] = (int)$xml->currentconditions->weathericon;// 03

// forecast
$day = count($xml->forecast->day);
for ($i = 0; $i < $day; $i++) {
$weather['forecast'][$i]['day_date'] = (string)$xml->forecast->day[$i]->obsdate;// 3/7/2010
$weather['forecast'][$i]['day_text'] = (string)$xml->forecast->day[$i]->daytime->txtshort;// 天气
$weather['forecast'][$i]['day_icon'] = (int)$xml->forecast->day[$i]->daytime->weathericon;// 08
$weather['forecast'][$i]['day_htemp'] = (int)$xml->forecast->day[$i]->daytime->hightemperature;// 69
$weather['forecast'][$i]['day_ltemp'] = (int)$xml->forecast->day[$i]->daytime->lowtemperature;// 57
}

echo json_encode($weather);


转换成.net有什么好方法？

[xray2005]

.NET Framework对于JSON本提供了很好的支持。

1. 使用JavaScriptSerializer，位于命名空间System.Web.Script.Serialization，使用如下：

序列化为JSON字符串：

C#代码

User user = new User {Name = "jquery", Age = 20};
JavaScriptSerializer serializer = new JavaScriptSerializer();
string result = serializer.Serialize(user);

反序列化JSON

C#代码

String input = "";
JavaScriptSerializer serializer = new JavaScriptSerializer();
serializer.Deserialize(input);

2. 使用DataContractJsonSerializer类，

推荐使用这个，这是最新的，位于命名空间System.Runtime.Serialization.Json下，序列化和反序列化分别调用它的WriteObject()和ReadObject()方法就可以了。

如何取十楼 对应数据？

[liyoubaidu]

不知道是不是叫linq

[liyoubaidu]

不知道是不是叫linq 回复内容

这楼对框架很精通啊
