Debug c++ dll in C#
提问by
I have a .dll from c++ and I want to debug it in C#, but I don't know how to.
我有一个来自 c++ 的 .dll，我想在 C# 中调试它，但我不知道如何。
When I compiled the c++ project, Visual studio asked me to execute an ".exe".
当我编译 c++ 项目时，Visual Studio 要求我执行一个“.exe”。
I supposed that I had to create a project to execute the dll.
我想我必须创建一个项目来执行 dll。
But I am lost, how could I debug it?
但是我迷路了，我怎么调试呢？

Visual Studio cannot execute a dll on its own.
Visual Studio 无法自行执行 dll。
You need to set the startup .exe that will be using your C++ dll in the properties of your dll project. You can do so from properties --> debugging --> commandspecifying the path of the executable that's gonna call your dll and any command line argument needed.
您需要在 dll 项目的属性中设置将使用 C++ dll 的启动 .exe。您可以从属性 --> 调试 --> 命令指定将调用您的 dll 的可执行文件的路径以及所需的任何命令行参数。

If I understand you correctly, you want to debug a C++ coded DLL that you created, in a C# project that calls the DLL, which you also created?
如果我理解正确，您想在调用 DLL 的 C# 项目中调试您创建的 C++ 编码的 DLL，该 DLL 也是您创建的？
I've done this before by going into your C# project properties, and under the Debug section, checking the "Enable unmanaged code debugging" check box. This should allow you to step into your C++ DLL.
我之前通过进入 C# 项目属性并在“调试”部分下选中“启用非托管代码调试”复选框来完成此操作。这应该允许您进入您的 C++ DLL。

To debug a C++ from C# there a couple of things you have to do.
要从 C# 调试 C++，您必须做几件事。
- Add a C# project to you solution for your debug application.
- Edit the properties of the C# project to "Allow unmanaged code debugging" on the "Debug" tab of the project properties.
- Set the C++ project as a dependency of the C# project.
- Write code in your C# project to use the DLL either using P/Invoke or COM.
- Set some breakpoints in your C++ code and run the C# project.
- 将 C# 项目添加到调试应用程序的解决方案中。
- 在项目属性的“调试”选项卡上，将 C# 项目的属性编辑为“允许非托管代码调试”。
- 将 C++ 项目设置为 C# 项目的依赖项。
- 在 C# 项目中编写代码以使用 P/Invoke 或 COM 使用 DLL。
- 在 C++ 代码中设置一些断点并运行 C# 项目。

For VS 2017 Pro, go to the property page of the main project (your c# project in the solution) by right mouse clicking it. At the Debug menu item, find the option in Debugger engines, choose Enable native code debugging.
对于 VS 2017 Pro，通过鼠标右键单击它转到主项目（解决方案中的 c# 项目）的属性页面。在调试菜单项中，找到调试器引擎中的选项，选择启用本机代码调试。
