Interpretation of ASP. NET 5 MVC6 series of tutorials (7): dependency injection, interpretation of ASP. NET In the previous section (Middleware), we mentioned the Dependency Injection function, ASP. NET 5 officially implements fu

that the DataGrid can implement. The Repeater control has the least functions, but is very user-defined. Due to the reduction of many functions, the performance of the server is minimized. Therefore, when you simply need to display the data list, you can select the Repeater or DataList control to achieve the same purpose and reduce the performance overhead. Using the above ASP.

the encoding principles and language sets in the view must be processed in the code-behind corresponding to each Aspx. Therefore, this is not suitable for the development, expansion, and maintenance of large systems. Although this architecture can also achieve a virtual three-layer or multi-layer architecture, it is also the limit of ASP. NET 2.0. To Model 2, also known as the MVC Framework, the controller

exceeding the connection limit. 2. Use stored procedures Stored procedures are a set of pre-compiled SQL statements stored on the server, similar to the batch processing files in the DOS system. Stored Procedures provide the ability to access databases immediately and process information quickly. Using the stored procedure can avoid multiple compilation of commands. After one execution, the execution plan will reside in the cache. In the future, you only need to directly call the binary cod

A Controller requires a Repository, so this Repository is a dependency of the Controller. The above is a traditional Deoendency example (in code ). The Dependency Reolver is provided in ASP. net mvc 3, which provides us with a good Dependency Resolut

However, after running the conversion wizard, you may find that some code separation files (for example, *. aspx. CS or *. ascx. VB) are moved to the app_code directory. This indicates that the content page of the code separation file contains the codebehind instruction in incorrect format and is not co

ASP. NET 2.0 retains all the caching functions of ASP. NET 1.1. It also adds new functions and enhances existing functions. The new features include cache configuration files, custom cache dependencies, SQL cache dependencies, and creating dynamic content on the cache page (with cache replacement ). Enhanced functions
