Talking about the use method of the include of asp.net _ practical skill

We have learned the code to separate the methods of different files, mainly including:

Assembly. dll, <inherits Src>.cs, <script src>.cs, user control. ascx, include, Response.WriteFile ()

Assembly. DLL: This is the most advanced method, referencing a DLL (assembly) file that is compiled to IL.

<inherits Src>.cs: In this way, you can first define a new class that inherits the page class, and then process the class in the Aspx/ascx file.

<script Src>.cs: The <script runat= "Server" > part can be separated into a new file.

User control. ascx: The introduction of a piece of ASP.net code as a control.

Include: This is today's topic, as detailed below.

Response.WriteFile (): He can only be used to introduce a section of "Pure client code (DHTML)", the extension can be arbitrary.

Experiment Project Description:

I think there is nothing more than a UI to illustrate the problem, then what is this page?

This is a typical "up and down" structure of the Web page, in the implementation: "Header/Footer" may be unchanged, and the middle may be changed.

So in practice, if you use the "include" method, we need to separate the three parts to be a single file.

After that, you can use a "master file" to include three files in each.

And today, we are just an experiment, so we designed this:

The middle is a "master file," and then the next two sections are included.

Finally, we will summarize some of the key technologies.

Code implementation:

"Upper part file: Head.aspx"

Copy Code code as follows:

Pass:<asp:textbox id= "Text2" runat= "Server"

textmode= "Password"/>

<asp:button id= "button1" runat= "Server"

"Upper part file: End.a"

User ' s pass: <b><asp:label Id=label2 runat=server/></b>

<!--#include file= "END.A"-->

</form>

Key Technologies • Accounts:

What else does the example above illustrate?

L include a few files that end up in a single file, and as each page of the element, it's just a fragment of the final page that you spelled.

L The pages that are spelled, the final pages, are asp.net code containers, not HTML text.

L The page is spelled in order.

L These files in the code, when spelled, just plain text, when the final spell, will be checked/compile/error/show ...

L A file can include another file multiple times. However, the premise is that the Declaration/definition (identifier) portion cannot be duplicated (the duplicate name).

L If you end up with a "runat=server" control in each file, be sure to pay attention to the <form runat= the start/end position of the "server" >.

L A page can only have one <form runat= "Server", even if you can set the ID of the form cannot have more than one.

L A page may appear multiple times <script runat= "Server", and it will run before this "final page" display.
Also, it runs independently of the page order, which is a "code declaration block" whose elements are only invoked and then run.

L We can put the <script runat= "Server" >, anywhere on the page, including <form runat= "Server" >.

L Use the Include method to refer to the file, and the extension is optional.
