如何在 VisualStudio 中设置路径？

如何设置单独在 VisualStudio 中搜索特定项目的 DLL 文件的路径？

现在我正在设置它在环境 path变量，但我想更好地控制这一点。

Set the PATH variable, like you're doing. If you're running the program from the IDE, you can modify environment variables by adjusting the Debugging options in the project properties.

If the DLLs are named such that you don't need different paths for the different configuration types, you can add the path to the system PATH variable or to Visual Studio's global one in Tools | Options.

You have a couple of options:

  • You can add the path to the DLLs to the Executable files settings under Tools > Options > Projects and Solutions > VC++ Directories (but only for building, for executing or debugging here)
  • You can add them in your global PATH environment variable
  • You can start Visual Studio using a batch file as I described here and manipulate the path in that one
  • You can copy the DLLs into the executable file's directory :-)

If you only need to add one path per configuration (debug/release), you could set the debug command working directory:

Project | Properties | Select Configuration | Configuration Properties | Debugging | Working directory

Repeat for each project configuration.

Search MSDN for "How to: Set Environment Variables for Projects". (It's Project>Properties>Configuration Properties>Debugging "Environment" and "Merge Environment" properties for those who are in a rush.)

The syntax is NAME=VALUE and macros can be used (for example, $(OutDir)).

For example, to prepend C:\Windows\Temp to the PATH:

PATH=C:\WINDOWS\Temp;%PATH%

Similarly, to append $(TargetDir)\DLLS to the PATH:

PATH=%PATH%;$(TargetDir)\DLLS

None of the answers solved exactly my problem (the solution file I was running was trying to find xcopy to copy a dll after generation).

What solved it for me was going into menu "Project -> Properties"

Then in the window that opens choosing on the left pane: "Configuration Properties -> VC++ Directories

On the right pane under "General" choosing "Executable Directories "

And then adding: 

$(SystemRoot)\system32;$(SystemRoot);$(SystemRoot)\System32\Wbem;$(SystemRoot)\System32\WindowsPowerShell\v1.0\;$(ExecutablePath)
