See the MVP using WebClient and WebRequest classes to get the Web page source code so want to write their own point, of course, refer to its approach.
This time I downloaded the Visual Web Developer
The code was written in the previous article,
My btn function is as follows
String urlpage = "";Urlpage = Urltext.text;WebRequest request = WebRequest.Create (urlpage);WebResponse response = Request. GetResponse ();Stream Resstream = Response. GetResponseStream ();StreamReader
This article is written a long time ago, just turned over the hard drive, and now put it out. This is just a formal idea, temporarily no time to implement, I have simply verified the formal process, the temporary has not found a problem, but do not guarantee that the process is not a problem. If you find a problem, please correct me, thank you!

A better C ++ serialization/deserialization library Kapok
1. Features of Kapok
Simple, easy to use, header-only, only need to reference Kapok. hpp; efficient, preliminary testing is equivalent to messagepack.
It is implemented in pure c ++ 11, so it must support the C ++ 11 compiler.
2. Main Functions
Automatic serialization and deserialization of objects are very easy to use. Let's look at a serialization/deserialization example of a tuple.
// Serialization

(String FileName) { string filecontents; using (StreamReader sr = new StreamReader (FileName)) { filecontents = Sr. ReadToEnd (); } File.delete (FileName); return filecontents;}
This code has a problem, the ReadToEnd method may throw an exception, then the temporary file can not be deleted. So some people change the code to:
String Readtempfile (String FileName) { try {
SubPublic Sub ReadFileRun ()Dim sr As System. IO. StreamReader = New StreamReader (FilePath, System. Text. Encoding. Default, True)Do While sr. Peek>-1Dim Tempsr As String = sr. ReadLine vbCrLfIf DoMainAddress. Contains (Tempsr) = False ThenDoMainAddress. Add (Tempsr)End IfLoopSr. Close ()Dim wrstr As String = ""For I As Integer = 0 To DoMainAddress. Count-1Wrs
