asp.net向api发送获取请求并获取json结果

Question

How can I send 'get' request from the server to API and get result with json data? I heard about HTTPClient in .net 4.5 maybe there is something like that in .net 4.0?

Answer 1

For older Framework version You can use either WebClient which is really simple class for downloading/uploading data, or use HttpWebRequest . WebRequest is lower level, but You can define method(GET,POST), UserAgent etc. Here You can find example about using WebRequest to do POST.

If You just want to get returned JSON from adress, WebClient should be sufficent.
