最近做C#上传，不过在使用HttpWebRequest时遇到了奇怪的超时问题，一时无法解决。
于是找找其他办法，发现了RestSharp，快捷，好用，用法如下：
using RestSharp;
string url = "http://...";
string content = "..."; //要发送的内容
string contentType = "application/json"; //Content-Type
try
{
var client = new RestClient(url);
var request = new RestRequest(Method.POST);
request.Timeout = 10000;
//request.AddHeader("Cache-Control", "no-cache");
request.AddParameter(contentType, content, ParameterType.RequestBody);
IRestResponse response = client.Execute(request);
return response.Content; //返回的结果
}
catch (Exception ex)
{
return "连接服务器出错：\r\n" + ex.Message;
}支持文件：RestSharp.dll
