Asp.net的post提交方式

在网上找了半天Asp.Net的Post提交方式,,代码都一样.
string url = "网址";
HttpWebRequest req =(HttpWebRequest)WebRequest.Create(url);
string s = "要提交的数据";
byte[] requestBytes = System.Text.Encoding.ASCII.GetBytes(LoginInfo);
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
req.ContentLength = requestBytes.Length;
Stream requestStream = req.GetRequestStream();
requestStream.Write(requestBytes, 0, requestBytes.Length);
requestStream.Close();

HttpWebResponse res = (HttpWebResponse)req.GetResponse();
StreamReader sr = new StreamReader(res.GetResponseStream(), System.Text.Encoding.Default);
string backstr =sr.ReadToEnd();
Response.Write(line);
sr.Close();
res.Close();
..
LoginInfo跟line是什么意思啊..不懂.放在代码里报错,当前上下文中不存在..
求解...!

Answer 1

//建立WebRequest对象，url目标地址
HttpWebRequest req =(HttpWebRequest)WebRequest.Create(url);

//这里的s 是啥个东西？？搞不懂
string s = "要提交的数据";

//将LoginInfo转换为byte[]格式，这里的LoginInfo应该是你要传输的数据
byte[] requestBytes = System.Text.Encoding.ASCII.GetBytes(LoginInfo);

//设置请求为POST方式,
req.Method = "POST";

//设置请求类型
req.ContentType = "application/x-www-form-urlencoded";

//请求发送的数据长度, 这里就很清楚了，请求数据是从LoginInfo转换来的
//前面的代码byte[] requestBytes = System.Text.Encoding.ASCII.GetBytes(LoginInfo);
req.ContentLength = requestBytes.Length;

//建立请求的输入流
Stream requestStream = req.GetRequestStream();

//从requestBytes中读取数据到输入流中
requestStream.Write(requestBytes, 0, requestBytes.Length);

//关闭输入流
requestStream.Close();

//获取响应对象
HttpWebResponse res = (HttpWebResponse)req.GetResponse();

//获取服务器返回流
StreamReader sr = new StreamReader(res.GetResponseStream(),System.Text.Encoding.Default);

//读取返回流数据，并赋值给backstr
string backstr =sr.ReadToEnd();

//页面输出line???? 应该是backstr 吧
Response.Write(line);

//关闭* 2, 不解释了
sr.Close();
res.Close();

给附加分吧!!!!!

Answer 2

你先要定义这两个变量
LoginInfo是指你要转换为数据流提交的数据

line是指获取该数据

追问

只需要定义..需要赋值吗`?
