This article mainly introduces Asp.net how to dynamically generate html pages, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

This function is suitable for web sites where the background database function is not strong, that is, most of the text is not stored in the database records, but in the html file or xml file, only the index is placed in the database, such as article title, category, query keywords and so on. This is suitable for Web sites that do not have database support such as MS Sql Server in the background.

Suitable for news release systems, such as sina, 163,etc., all use dynamic generation of html pages.

It is suitable for programs that need to customize pages dynamically. Such as forums, chat rooms and so on. You can load customized html pages to enhance beauty.

Train of thought

1. Use tools such as Dw-Mx to generate a template in html format, add a special tag (such as $htmlformat$) where you need to add a format, read the template using code when dynamically generating a file, then get the input from the foreground, add it to the tag location of the template, generate a new file name, write it to disk, and then write relevant data to the database.

two。 Use background code to hard-code Html files, and you can use HtmlTextWriter classes to write html files.

Advantages

1. Can build a very complex page, using the method to include js files, in the js file to add [xss_clean] () method can be added in all pages, such as page headers, advertisements and other content.

two。 Static html files can use MS Windows2000's Index Server to build a full-text search engine, and asp.net can be used to get search results in the form of DataTable. Win2000's Index service cannot find the contents of XML documents. If you include database search and Index index double lookup, then this search function will be very powerful.

3. Save the load on the server, requesting a static html file saves a lot of resources than an aspx file server.

Shortcoming

Idea 2: if you use hard-coding, the workload is very large, requiring a lot of html code. Debugging is difficult. And the html style generated by hard coding cannot be modified, so if the website changes the style, it must be re-coded, bringing a huge workload to the later stage.

So the first way of thinking is adopted here.

Display code

1. Define (template.htm) html template page

The copy code is as follows:

$htmlformat [3]

2.asp.net Code:

The copy code is as follows:

/ /-read the html template page into the stringbuilder object-

String [] format=new string [4]; / / define an array with the same number of htmlyem tags

StringBuilder htmltext=new StringBuilder ()

Try

{

Using (StreamReader sr = new StreamReader ("path and page name where the template page is stored")

{

String line

While (line = sr.ReadLine ())! = null)

{

Htmltext.Append (line)

}

Sr.Close ()

}

}

Catch

{

Response.Write ("alert ('error reading file')")

}

/ /-assign values to the tag array-

Format [0] = "background=/" bg.jpg/ ""; / / background picture

Format [1] = "# 990099"; / / font color

Format [2] = "150px"; / / Font size

Format [3] = "generated template html page"; / / text description

/ /-replace the tag in htm with the content you want to add
