[Original] handy little tool development-Preliminary Statistics on the response rate of blog posts on the blog homepage

[Open the engine]

I often habitually open the homepage of my blog and read some wonderful technologies.ArticleThe technical atmosphere here is very good, and everyone's enthusiasm for Writing blog posts has always infected me.

Today, at noon, I suddenly had an idea: Count the response rate of these blog posts on the blog homepage. Because we had a one-hour break at noon, we just made a general function implementation, without much modification or input verification.

[Development implementation]

The implementation process is also very simple.

1. Create a winform project, draw a simple form, and drag several controls.

"How many pages are counted" means the number of pages on the homepage of the blog garden to be counted.

II. Implementation ideas:

1. Construct a list to store the pagination URL for Statistics

2. Obtain HTML for each URLSource codeThen, the number of comments and the number of reads are retrieved by string retrieval, locating, stripping, and re-retrieval, and saved as a key-value pair to a dictionary <>.

3. collect statistics on the data in dictionary <>, splice the string, and display it to textbox.

III,CodePart

Dictionary < Int , Int > Commentandread = New Dictionary < Int , Int > ();  Private   Int  Totalcomment;  Private   Int  Totalread;  Private   Void Tongji_click ( Object  Sender, eventargs e ){ //  Construct multiple URLs based on the number of pages.              Int Pagecount = convert. toint32 ( This  . Txtpage. Text); List < String > Pageurls = New List < String > ();  For ( Int I = 1 ; I <= pagecount; I ++){  If (I = 1  ){  String Url = @"  Http://www.cnblogs.com/index.html  "  ; Pageurls. Add (URL );}  Else  {  String Url = @" Http://www.cnblogs.com/  " + "  P  " + I; pageurls. Add (URL );}}  //  Read HTML code by URL              Foreach ( VaR URL In  Pageurls ){  String Strhtml =""  ; WebClient WC = New  WebClient ();  # Region Because the company needs to use a proxy to access the Internet, you need to configure the proxy server first.

Add (read, comment );}  Catch  {  //  The number of blog posts with the same read volume exists. skip this step. }  String Htmlretain = Htmlcut. substring (readend); htmldispose (htmlretain );}  Else  {  Return  ;}}

[Summary]

According to statistics, the response rate of blog posts on the blog homepage is about 5‰. I personally think it is not very high. I hope you can reply a lot, your reply is the motivation for bloggers to launch more originality!
