对于.cs文件，Visual Studio 2015解决方案资源管理器中的虚线文件图标的含义是什么？

Question

What does this dotted file icon mean? It's a .cs file but it is not behaving right in my project and I've noticed this separate icon in Solution Explorer:

I've checked the MSDN Documentation in three places

Another page at MSDN

Yet another page at MSDN

I've also checked the Visual Studio Documentation itself, which is rather obscurely organized.

I've even checked this website:

Lastly, I found this topic with a similar question but both the question page and the references inside do not have this icon . Thanks for your help.

Answer 1

This means that the file isn't included in the project. You're only seeing it because you turned on Show All Files.

You should right-click the file and click Include in Project.

Answer 2

You have " Show all files " checked.

The dotted lines indicate files that have not been added to your project.

Right click on the file and click "Include in project" to include the file in your project.

Answer 3

That "dotted" icon mean that that file is not a part of your project or it is hidden and it is not included in your project.

That "dotted" icon is pretty similar to the icon in Solution Explorer called "Show all files". When you click on it you can see all the files and maybe you click on it or you have some issue and your file is not included in the project.

To include it you can right click one of those files go to Include In Project and that will add it to the project, which declares it in the manifest of your project. You can do it like this:

Answer 4

它不包含在您的项目中和/或隐藏。
