c# HttpWebRequest 模拟HTTP post 传递JSON参数

//HTTP post JSON 参数

private string HttpPost(string Url, Object ticket)

{

DataContractJsonSerializer serializer = new DataContractJsonSerializer(ticket.GetType());

MemoryStream stream = new MemoryStream();

serializer.WriteObject(stream, ticket);

byte[] dataBytes = new byte[stream.Length];

stream.Position = 0;

stream.Read(dataBytes, 0, (int)stream.Length);

string param = Encoding.UTF8.GetString(dataBytes);

byte[] bs = Encoding.ASCII.GetBytes(param);

HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(Url);

req.Method = "POST";

req.ContentType = "application/x-www-form-urlencoded";

req.ContentLength = bs.Length;

using (Stream reqStream = req.GetRequestStream())

{

reqStream.Write(bs, 0, bs.Length);

}

HttpWebResponse hwr = req.GetResponse() as HttpWebResponse;

System.IO.StreamReader myreader = new System.IO.StreamReader(hwr.GetResponseStream(), Encoding.UTF8);

string responseText = myreader.ReadToEnd();

return responseText;

}

导入对应的dll , Object参数可以随意，实体类传什么，json参数就是什么。
