Reviewing file types in C#.NET

Create Code-39 in C#.NET Reviewing file types

Make a new ASPNET Web site called 5, and save it in the default location Visual Studio makes a new site for you, in the specified folder Three files are added:

Defaultaspx: This is the starter markup file Has the HTML and ASPNET controls Defaultaspxcs: The code-behind file for the Defaultaspx file Webconfig: The magic configuration file A lot goes into this one There is also an App_Data folder This is used by Visual Studio and ASPNET to store, for instance, a SQL Lite database that you might make to store your application data Just leave it there for a second You just know we need a few new files, right We should add a style sheet, and maybe a script file or two Right-click on the project and select Add New Item You can add an absurd number of files to a site just look at Figure 5-3 Global Application Class Silverlight-enabled WCF Service What are these things Does anyone actually use this stuff Yes, but don t sweat it too much You need to worry about only a few file types to make a good application, like these: Master page: This is the template for the site We handle these in the next section Style sheet: This is the CSS 20 style for your application If you aren t familiar, refer to HTML and CSS For Dummies great book Jscript file: So named because Microsoft can t say JavaScript anymore or the lawyers beat them up Class: Just your basic C# class, in its own file That s what you need Now to organize them

You have two choices when organizing your Web site You can build a few projects to manage your files, or you can build folders into the Web project and put your files there My usual methodology is to build separate projects for the class files and folders for the Web-related files This way, if you want to reuse the classes for a Windows Mobile application, you can easily just reference the class file project Web files should be in folders in the Web application Note that this can have some implications for referencing files If your project isn t the root of a Web server, you might have to carefully consider how to reference files If you are deploying your Web site to a domain, like wwwmynewWebsite com, you can use a / to refer to files, like this:

If you aren t deploying to a domain for instance, if you are making an application that lives in a folder of a site, such as wwwsomeoneelses sitecom/myApplication, you can t use / because you don t know how far away the root of the application is, or what the directory really is ASPNET can handle this problem for you A construct in ASPNET is implemented with the tilde (~), but it works only in ASPNET controls That means that the img HTML tag won t work with a tilde; you have to use the asp:Image control, like this:

For organization, I have a pattern It may or may not work for you Please feel free to make your own Mine breaks down like this: I put my class libraries in a separate project Usually, I have a business logic layer (or controller) in a second project, and a data access layer (or model) in a third project I add a Bits folder, and in that, I put folders for, well, all the bits Style sheets Images JavaScript files Whatever else I then make a root level folder for every section of the site If I have three top level menu items in my site, I have three folders If I just have application files, and don t have a regular menu structure, everything will be in the root
