Visual Studio创建的WebForms与空白文件

Question

When trying to write the codebehind file for its associates aspx page a colleague and I were stumped as to why the Controls within file.aspx were not appearing in the codecompletion, nor were they compiling without error.

When i created the file.aspx and file.aspx.cs I had created these items as blank files, the file.aspx.cs build action was set to Compile while the file.aspx Build Action was Content.

We created a new "webform" item that automatically generated the SecondFile.aspx and the SecondFile.aspx.cs file and associated them. We copied the HTML and code from file to SecondFile and the code completion worked, and the codeBehind compiled correctly.

Why?

您没有提供足够的信息，但是我认为您可能忘记了将页面声明放在.aspx文件的顶部

<%@ Page Language="C#" CodeFile="file.aspx.cs" Inherits="my_ascx_class_name" %>
