using classes in System.Net, see

Retrieving HTTP content in .NET
http://www.west-wind.com/presentations/dotnetWebRequest/dotnetWebRequest.htm


string strId = UserId_TextBox.Text;
string strName = Name_TextBox.Text;

ASCIIEncoding encoding=new ASCIIEncoding();
string postData="userid="+strId;
postData += ("&username="+strName);
byte[] data = encoding.GetBytes(postData);

// Prepare web request...
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("http://localhost/MyIdentity/Default.aspx?x=2&y=2");
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);++++问点1？？
newStream.Close();

HttpWebResponse res = (HttpWebResponse) myRequest.GetResponse();


Encoding enc = System.Text.Encoding.GetEncoding("GB2312");


StreamReader sr = new StreamReader(res.GetResponseStream(),enc);


string sHtml = sr.ReadToEnd();


sr.Close();

res.Close();

问点1：newStream.Write(data,0,data.Length);此处是否该为：newStream.Read(data,0,data.Length);

问点2：“myRequest”在什么地方读取的“data”?

问点3：我写的一个给短信网关发送信息的功能为什么运行一次总收到两条短信？代码如下：（大概是这些）
WebRequest re = (HttpWebRequest)WebRequest.Create("http://url?name=strName&pwd=strPwd&message=string&.......");
webResponse rp = (HttpWebResponse)re.GetResponse();

问点1、2我已明白！是理解错误了！
还是请问问点3？？？

>>>为什么运行一次总收到两条短信？

make sure the above code is not executed twice

[wulibinbrain]

>>>make sure the above code is not executed twice

这一点也是我困惑的？
我想问“WebRequest re = (HttpWebRequest)WebRequest.Create("http://url?name=strName&pwd=strPwd&message=string&.......");”这一步是在创建HttpWebRequest；发送是在这一步：“webResponse rp = (HttpWebResponse)re.GetResponse”是不是发送后因为网络响应慢，他没有即时接到响应自己又请求了一次呢？
如果是如何做到等待响应，而只请求一次呢？

[saucer]

>>>又请求了一次呢？

shouldn't, 只请求一次, try to add a break point in your code, I would think it is executed twice, or something is wrong with your 网关

[wulibinbrain]

网关没问题的，我直接把请求串加到ie上访问收到一次信息。
可以写一下发送的代码吗？如何做到“add a break point”？

[saucer]

what I meant is to try to debug your code to see if your code is executed twice

[wulibinbrain]

可以用中文表述详细些吗？

[saucer]

在VS.NET里调试你的编码，我的感觉是你的编码执行了2次

如果是事件函数的话，有可能被绑定了2次

请问“saucer(思归/MVP) ”
我现在用Tcp的方式发送短信，但遇到一个问题：在C#中用System.Net.Sockets.TcpClient创建实例：
TcpClient tClient = new TcpClient();
try
{
tClient.Connect("202.99.114.235",8020);
NetworkStream stream = tClient.GetStream();
string strLongin = "Login Name=xxx&Pwd=xxx&Type=x";
byte[] data = System.Text.Encoding.ASCII.GetBytes(strLongin);
stream.Write(data,0,data.Length);
=====================================================================
在C#中stream.Write()方法的参数中只支持byte[],如何象Delphi中的TcpClient.WriteLn()方法直接可以发送string，在C#中有否与之相当的方法？

[saucer]

chain the stream, for example

tClient.Connect("202.99.114.235",8020);
NetworkStream stream = tClient.GetStream();
StreamWriter sw = new StreamWriter(stream, System.Text.Encoding.ASCII);
string strLongin = "Login Name=xxx&Pwd=xxx&Type=x";
sw.Write( strLongin);
....;

多谢 saucer 的指点！
