该文件无法添加到项目中.该文件在项目目录树错误中 [英] The file could not be added to the project. This file is within the project directory tree error

问题描述

每当我尝试将文件添加到Visual Studio项目时，都会收到以下警告:

Whenever I try to add a file to my Visual Studio project, I get the following warning:

无法将文件[文件名]添加到项目中.该文件位于项目目录树中

The file [filename] could not be added to the project. This file is within the project directory tree

如何解决此错误?

推荐答案

进入Windows文件资源管理器并导航到.csproj文件，然后使用记事本(或高级文本编辑器，如NotePad ++)将其打开

Go in to your Windows File Explorer and navigate to the .csproj file and open it with Notepad (or advanced text editor like NotePad++)

您会注意到两行具有相似或重复的编译包含"行:

You will notice two lines that have similar or duplicate Compile Include lines:

<Compile Include="..\ProjectDir\SubDir\MyClass.cs">
  <Link>"SubDir\MyClass.cs"</Link>
</Compile>

删除上一行"并仅保留与下一行类似的行:

Remove the Above line and keep only the line similar to the one below:

<Compile Include="SubDir\MyClass.cs" />
