난이도 :
(조금씩 어려워져요 ^^)답변형게시판도 만들자 - 공통클래스 작성
우선, 답변형 게시판을 위해서 App_Code 폴더에,
Library.cs 와 Multiboard.cs를 만든다.
아래는 Multiboard.cs의 소스코드이다.
11 using System.Data.SqlClient;
12
13 public class Multiboard

15 // 게시물리스트에 사용하는 메서드 DataSet을 돌려준다.

꽤나 많은 소스를 다 적었다. 우선 다음으로 Library.cs 소스코드이다. 공통라이브러리는 메시지창이나 메시지창 후 페이지 이동하는 웹 사이트 어디에서나 쓸 수 있는 공통메서드들을 모아둔 클래스이다. 또한 static으로 작성하여 인스턴스를 생성할 필요도 없이 바로 사용할 수 있다.
11 public class Library
12 {
13 public static void Alert(HttpResponse response, String msg)
14 {
15 String script = "<script type='text/javascript'>alert('" +
16 msg + "');</script>";
17 response.Write(script);
18 }
19
20 public static void Alert(HttpResponse response, String msg, String strUrl)
21 {

23 msg + "');location.href='" + strUrl + "';</script>";

25 }
26
27 public static string SubstrTitle(string title, int size)
28 {
29 return title.Length > size ? title.Substring(0, size) + "..." : title;
30 }
31
32 public static string ConvertDateWithHyphen(string date)
33 {
34 return date.Substring(0, 4) + "-" + date.Substring(4, 2) + "-" + date.Substring(6, 2);
35 }
36 }
