Implementing news pagination with ASP.net

Asp.net| Page idea: When adding news in the background, it is estimated that a tag should be inserted where the page should be paginated (I inserted [page]) and when shown in the foreground, I pass in a parameter page that indicates the page to display, and in the Display page, I follow the tag [page] Put the news content into the array separately, if the value of the passed parameter page is 1, I will take the value of arr[0], if it is the second ...
Also, I put the pagination of the HTML code is based on the statistics [page] to determine whether to display

Baseinfo is the basic information class that I define:

public class Baseinfo
? {
?? public string id,summary,content,picture;
?? Public DateTime Publictime;

?? Public StringBuilder pagefoot = new StringBuilder ();

?? Public Baseinfo ()
?? {?
???
??}

?? Add to
?? public int Add ()
?? {
??? ...??
??}

?? Update
?? public int Update ()
?? {
??? ...
??}
??
?? Class
?? public void Init ()
?? {
??? ...
??}
?}


In this page to pass in two parameter page and ID, the first link to this page should be 1, and must be 1,id is

The ID of the news, such as news id=1 connection should be baseinfodetail.aspx? Page=1&id=1
Nextat is the position of the next [page], Backat is the position of the previous [page] flag, Pagefoot is an HTML table I added

Runat=server
The code is as follows:
Part of the code for Baseinfodetail.aspx is as follows:
Baseinfo info = new Baseinfo ();??
???? Info.id = request.querystring["ID"];?
???? Info. Init ();

????

???? for (int j=1;j<=i;j++)
???? {
????? Info. Pagefoot.append ("[

Href= ' baseinfodetail.aspx? Page= "+j.tostring () +" &id= "+info.id+" ' > "+j.tostring () +"]

");
????}
???? if (currentpage!= i)
???? {
????? CurrentPage + 1;
????? Info. Pagefoot.append ("next page");
????}
