问题描述
我正在尝试向输出窗口写一个消息进行调试。我搜索了一个函数，如Java的 system.out.println（）。我试过 Debug.Write ， Console.Write 和 Trace.Write 。它不会发出错误，但它也不会打印任何东西。
I am trying to write a message to the output window for debugging purposes. I searched for a function like Java's system.out.println(""). I tried Debug.Write, Console.Write, and Trace.Write. It does not give an error, but it does not print anything either.
定义DEBUG常量和定义TRACE常量选项。
"Define DEBUG constant" and "Define TRACE constant" options are checked.
菜单工具→选项→调试→将所有输出窗口文本重定向到立即
Menu Tools → Options → Debugging → "Redirect all Output Window text to the Immediate Window" option is not checked.
配置：Active（Debug）
Configuration: Active (Debug)
注意：我使用向导创建一个项目为Windows窗体应用程序，如果相关。我不知道在哪里看。
Note: I created a project with the wizard as "Windows Forms Application" if relevant. I have no idea where to look.
推荐答案
添加 System.Diagnostics 命名空间，然后您可以使用 Debug.WriteLine（）快速打印到IDE输出窗口的消息。有关详细信息，请参阅这些：
Add the System.Diagnostics namespace, and then you can use Debug.WriteLine() to quickly print a message to the output window of the IDE. For more details, please refer to these:
