请帮助我如何获取字符串并获取Asp.net(c#)中的数据。
答案 0 :(得分:3)
C#是使用此类提供System.Net获取字符串的WebClient类,如
var json = new WebClient().DownloadString("url");
答案 1 :(得分:1)
您可以使用JavaScript Serializer。
请参阅以下问题解答。 Parsing JSON using Json.net
答案 2 :(得分:1)
文本可以使用WebClient读取。可以使用javascriptSerializer将此结果更改为对象表示法。
答案 3 :(得分:1)
您需要将任务分解为步骤,。
首先以字符串格式获取网址
string url = HttpContext.Current.Request.Url.AbsoluteUri;
然后,您需要提取JSON格式的数据并将其放入文件(保存)
File.WriteAllText(@" c:\ url.json",url);
您可能必须使用Newtonsoft JSON.Net框架对其进行序列化。但是,我相信这是它的主旨。
答案 4 :(得分:1)
从网址获取字符串
string Strjson = new WebClient().DownloadString(UrlQuery);
将json字符串转换为Class Object
ClsObject = (ClsObject) Newtonsoft.Json.JsonConvert.DeserializeObject(Strjson);
或
ClsObject = Newtonsoft.Json.JsonConvert.DeserializeObject(Strjson,ClsObject);
需要将Newtonsoft库添加到项目中
