Display errors in the Common layer in the UI Layer

In Web development, the Common layer and UI Layer are relatively independent due to layered architecture development. Common Errors are usually stored in server logs, which are not visible to Common users. If you want to display errors in the Common Layer on the page, you can pass errors in the Common class as follows. Its core is
System. Web. HttpContext CT = System. Web. HttpContext. Current;
Obtains the Http HttpContext object of the current request. Then you can use the Requeset, Response, and Server objects.

Using System; namespace ContextTest {/// <summary> /// Class1 abstract description. /// </Summary> public class Class1 {public Class1 () {System. web. httpContext CT = System. web. httpContext. current; CT. response. write ("<input type = \" submit \ "name = \" Button2 \ "value = \" Button \"
Id = \ "Button2 \" onmouseover = \ "this. value = 'free' \ "onmouseout = \" this. value = 'billable '\ "/> ");}}}
