最简单的方法，我自己找到的

我试了很多次，直到找到一个可行的方法。例如，您想要将项目从sln文件夹移动到mySource文件夹。

Remove your Project: In the SolutionExplorer of Visual Studio select your Project you want to change the directory, Press Delete -> Project gets removed. It still remains in your sln folder. Copy it to your Path: In the windows explorer copy your whole project to your mySource folder. -> Now you are ready to include it. Include back your Project: In the SolutionExplorer of Visual Studio add Existing Project and select your project from mySource folder. -> Project is now back in your Solution. Adjust your Project References: Check every Reference in your Project. On your Project -> Dependencies -> Project -> you see your project references. If there is a yellow Warning sign on a project reference than is it wrong. Delete your project reference and add it new. Rebuild your Project: and let it Run. Afterwards you can delete your project in the sln folder, which is not anymore in use.

这工作。玩得开心!

对我有效的方法是:

从解决方案中删除项目。 使用文本编辑器编辑项目文件。 更新“包”的所有相对路径。就我而言，我不得不改变。\包裹到..\..\包，因为我把项目移动到一个更深的文件夹。 将项目加载回解决方案中。

这在VS2012中很简单;只需使用变更映射特性:

创建要将解决方案移动到的文件夹。 签入所有项目文件(如果您想保留更改)，或回滚任何签出的文件。 关闭解决方案。 打开源代码控制资源管理器。 右键单击解决方案，并选择“高级-> Remove Mapping…” 将“Local Folder”的值更改为步骤#1中创建的值。 选择“改变”。 通过在源代码控制资源管理器中双击解决方案来打开解决方案。

复制项目文件夹到新目标 从解决方案中删除项目(在“解决方案资源管理器”中右键单击项目并选择“删除”) 然后将现有项目添加到解决方案中(在“解决方案资源管理器”中右键单击项目，选择“添加”，然后选择“现有项目”) 将路径更改为“YourProjectName”中的“packages”文件夹。csproj"文件(在记事本中打开并更改链接包的路径)

我发现这个方法，这个方法对我有用。

在visual studio 2017社区版中，它在此路径创建一个项目 ”马克C: \用户\ \ \回购\产生来源\产生” 这将产生一个文件访问被拒绝的问题

现在，你可以用这种方法解决这个问题。

close your visual studio process. Then, find your project and copy the project folder But, first make a Sub-folder Named Projects inside of your visual studio 2017 folder in documents. Next, paste the project folder inside of your visual studio 2017 Project folder not the main visual studio 2017 folder it should go into the Sub-folder called Projects. Next, restart Visual studio 2017 Then, choose Open project Solution Then, find your project you pasted in your visual studio 2017 Projects folder Then clean the Project and rebuild it , It, should build and compile just fine. Hope, this Helped out anybody else. Not to sure why Microsoft thought building your projects in a path where it needs write permissions is beyond me.

在visual studio community 2019中，我做了Victor David Francisco Enrique说的，但只需要删除.vs invisible文件夹
