How can I use Web APIs to ensure data validity? In actual projects, no data is submitted to meet the requirements. Besides, there are more than N keywords in tianchao. Therefore, the following content adds web API data verification.Step 1 modify the Object Model Public Class Userinfo{ Public Int Id { Get ; Set ;}[Required][Stringlength ( 20 , Errormessage = "

There is no error in using ASP, as long as the application is sufficient. However, ASP. when developing a website or system, you should discard the habit of developing ASP. NET method, instead of ASP. NET.In the process of technological updates, there are still some people h

paging metadata contains the data totalCount, totalPages, prevPageLink, and nextPageLink. It is very useful for the client to return the data totalCount and totalPages, in this way, you can bind the results with some grids. Generally, we encapsulate paging metadata in the response Body. for developers, we provide all paging information. However, some API consumers only want to obtain the requested data without paging metadata. Therefore, it will be
