推荐答案
我使用这些功能,假设你的问题是关于一个窗体应用程序。结果
。您可以致电
I use these functions assuming your question is about a forms application.
You can call
HttpPost(
post_url,
"field_name_1", value_1,
"field_name_2", value_2,
...);
在这里,他们是:
Here they are:
public static string HttpPost(string url, params object[] postData)
{
StringBuilder post = new StringBuilder();
for (int i = 0; i < postData.Length; i += 2)
post.Append(string.Format("{0}{1}={2}", i == 0 ? "" : "&", postData[i], postData[i + 1]));
return HttpPost(url, post.ToString());
}
public static string HttpPost(string url, string postData)
{
postData = postData.Replace("\r\n", "");
try
{
WebRequest req = WebRequest.Create(url);
byte[] send = Encoding.Default.GetBytes(postData);
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
req.ContentLength = send.Length;
Stream sout = req.GetRequestStream();
sout.Write(send, 0, send.Length);
sout.Flush();
sout.Close();
WebResponse res = req.GetResponse();
StreamReader sr = new StreamReader(res.GetResponseStream());
string returnvalue = sr.ReadToEnd();
return returnvalue;
}
catch (Exception ex)
{
Debug.WriteLine("POST Error on {0}\n {1}", url, ex.Message);
return "";
}
}
