"Reprinted" to learn how to operate file streams in ASP. NET

Introduction:

In web development, operations on files are often performed.ProgramOne of the necessary lessons for design. Improving ASP. NET design capabilities, handling the use of controls, database operations, XML technology, and reading and writing files is also one of the secrets to improve web design and development.

This article uses a simple example to explain how to read text information on a web page to implement the ability to change the background of pages that do not often update information, because the information is not often updated, for example, there is no need to implement pages, website introductions, and website maps in the form of databases. The design complexity and system overhead are unnecessary.

Basic Information

Development Environment: vs2003 tool,. NET platform, C # Language

Key Technical Points: Reading and Writing of file streams in ASP. NET, dynamic use of table controls

Solution

1 worker. For the benefits, seeCode.

2. Add Table and set its style.

3. In page_load (), add the code implementation for loading text information.

1 private void page_load (Object sender, system. eventargs E)
2 {
3 // place user code here to initialize the page
4 // read the file path
5 string filenameurl = server. mappath (@ "blogtext \ url.txt ");
6 string filenamelnk = server. mappath (@ "blogtext \ link.txt ");
7
8 // read the text file to the file stream
9 streamreader srurl = new streamreader (filenameurl );
10 streamreader srlnk = new streamreader (filenamelnk );
11
12 string strurl, strlnk;
13
14 While (srurl. Peek ()! =-1)
15 {
16 strurl = srurl. Readline ();
17 strlnk = srlnk. Readline ();
18
19 // use two text files to easily separate URL and text
20 hyperlink hlnk = new hyperlink ();
21 hlnk. Visible = true;
22 hlnk. Text = strurl;
23 hlnk. navigateurl = strurl;
24
25 // other methods can be used for dynamic implementation
26 // Add text information to the table dynamically
27 tablerow TR = new tablerow ();
28 tablecell TC1 = new tablecell ();
29 tablecell TC2 = new tablecell ();
30
31 tc1.text = strlnk;
32 tc2.controls. Add (hlnk );
33 tr. cells. Add (TC1 );
34 tr. cells. Add (TC2 );
35 tabtext. Rows. Add (TR );
36
37}
38
39}
40

4. Run and check. OK.

Conclusion

File operations are the basic content of program development and need to be further improved. In the example in this article, you can try to use dataset and XML to implement it, which is more flexible. The specific ideas can be further explored.

I hope you will join the bricks and eggs, and I will try my best to move forward in the storm.
Enjoy.
