C#(WINFORM)实现模拟POST发送请求登录网站

最近接了个小项目，用到一个技术需要模拟POST向Web服务器发送请求来进行登录，下面写一下主要代码。
string strId = "admin";//用户名
string strPassword = "xxxxx";//密码
左手五个//string strsubmit = "YES";
ASCIIEncoding encoding = new ASCIIEncoding();
string postData = "urname=" + strId;
postData += ("&password=" + strPassword);
//postData += ("&Accept=" + strsubmit);
byte[] data = encoding.GetBytes(postData);
// Prepare
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("/login.aspx");
myRequest.Method = "POST";
myRequest.ContentType = "application/x-www-form-urlencoded";
myRequest.ContentLength = data.Length;
Stream newStream = myRequest.GetRequestStream();
// Send the data.
newStream.Write(data, 0, data.Length);
newStream.Clo();
// Get respon
HttpWebRespon myRespon = (HttpWebRespon)myRequest.GetRespon();
StreamReader reader = new StreamReader(myRespon.GetResponStream(), Encoding.UTF8);
string content = reader.ReadToEnd();
//Respon.Write(content);
textBox1.Text = content;
通过HttpWebRequest 发送POST 请求实现自动登陆[ 2006-09-15 16:17:12 | 作者: 景裔] 字体大小: 大| 中| 小
怎样通过HttpWebRequest 发送POST 请求到一个网页服务器？例如编写个程序实现自动用户登录，自动提交表单数据到网站等。
假如某个页面有个如下的表单（Form）：view plaincopy to clipboardprint?
<form name="form1" action="http:/login.asp" method="post">
<input type="text" name="urid" value="">
<input type="password" name="password" value="">
</form>
<form name="form1" action="http:/login.asp" method="post">
<input type="text" name="urid" value="">
<input type="password" name="password" value="">
</form>从表单可看到表单有两个表单域，一个是urid另一个是password，所以以POST 形式提交的数据应该包含有这两项。
其中POST的数据格式为：
表单域名称1=值1&表单域名称2=值2&表单域名称3=值3……
要注意的是“值”必须是经过HTMLEncode的，即不能包含“<>=&”这些符号。
本例子要提交的数据应该是：
urid=value1&password=value2
用C#写提交程序：view plaincopy to clipboardprint?
string strId = "guest";
string strPassword= "123456";
ASCIIEncoding encoding=new ASCIIEncoding();
string postData="urid="+strId;
postData += ("&password="+strPassword);
byte[] data = encoding.GetBytes(postData);
手术室设备// Prepare
HttpWebRequest myRequest =
(HttpWebRequest)WebRequest.Create("http:/login.asp");
myRequest.Method = "POST";
myRequest.ContentType="application/x-www-form-urlencoded";
myRequest.ContentLength = data.Length;
Stream newStream=myRequest.GetRequestStream();
// Send the data.
newStream.Write(data,0,data.Length);
newStream.Clo();
// Get respon
HttpWebRespon myRespon=(HttpWebRespon)myRequest.GetRespon(); StreamReader reader = new StreamReader(respon.GetResponStream(),Encoding.Default); string content = reader.ReadToEnd();
Console.WriteLine(content);
string strId = "guest";
string strPassword= "123456";
ASCIIEncoding encoding=new ASCIIEncoding();
string postData="urid="+strId;
postData += ("&password="+strPassword);
byte[] data = encoding.GetBytes(postData);
// Prepare
HttpWebRequest myRequest =
(HttpWebRequest)WebRequest.Create("http:/login.asp");
myRequest.Method = "POST";
myRequest.ContentType="application/x-www-form-urlencoded";
myRequest.ContentLength = data.Length;
Stream newStream=myRequest.GetRequestStream();
/
/ Send the data.
newStream.Write(data,0,data.Length);
