[Solved] WebProgramming Homework4-news crawling website

In this homework, you will design a news crawling website that parse news from a particular RSS and instantly updates itself.

You have to design one web page (RSSparsing.aspx) and a class page (News.cs) that holds news information.

News .cs

1. Add a class file named News.cs into your project (Add New Item, Class). This file will contain information about the news. If you encounter a message which states that this file should be in App_Code folder, then select Yes and let Visual Studio create the

App_Code folder for you and put News.cs file in this folder. After then, you will be able to use the News class in your application like any other classes of .NET library.

public class News

{ public int NewsID; public string Title; public string Description; public string Category; public string Author;

public DateTime PubDate; public string ImageUrl;

public News(int NewsID, string Title, string Description, string Category, string Author, string PubDate, string ImageUrl)

{

this.NewsID = NewsID; this.Title = Title; this.Description = Description; this.Category = Category; this.Author = Author; this.PubDate = PubDate; this.ImageUrl = ImageUrl;

}

}

Design of RSSparsing.aspx

This website will be use to parse the xml in the http://ajans.dha.com.tr/dha_public_rss.php. The following information about news will be downloaded and stored in a ArrayList. You can consider up to 20 news. Each news should be saved with unique id, which is called as NewsID. Information that are needed to be parsed are:

• Description
• Category
• Author
• PubDate
• ImageUrl

This information of news are located in <item> tag. Therefore, you should consider only <item> tags when parsing the xml file.

Check List of HW4:

1. You should retrieve all information of news from database.
2. Then store each news into a news object by using News.cs
3. Store each news object into an ArrayList.
4. Then bind the ArrayList into your gridview.
5. Your gridview should only show the _NewsID, Title and
6. You should use a Nuget logging package. You should write the exception message into logger file by using Nuget logging

You can use any Nuget logger package, but I found a special one, which is https://github.com/serilog/serilogextensionsloggingfile
