问题：
I am trying to write a message to the output window for debugging purposes. 我正在尝试将一条消息写入输出窗口以进行调试。 I searched for a function like Java's system.out.println("") . 我搜索了像Java的system.out.println("")这样的函数。 I tried Debug.Write , Console.Write , and Trace.Write . 我试过Debug.Write ， Console.Write和Trace.Write 。 It does not give an error, but it does not print anything either. 它不会出错，但也不会打印任何内容。 ide
"Define DEBUG constant" and "Define TRACE constant" options are checked. 选中“定义DEBUG常量”和“定义TRACE常量”选项。 函数
Menu Tools → Options → Debugging → "Redirect all Output Window text to the Immediate Window" option is not checked. 菜单工具 → 选项 → 调试 → “将全部输出窗口文本重定向到当即窗口”选项未选中。 工具
Configuration: Active (Debug) 配置：活动（调试） url
Note: I created a project with the wizard as "Windows Forms Application" if relevant. 注意：若是相关，我建立了一个项目，向导为“Windows窗体应用程序”。 I have no idea where to look. 我不知道在哪里看。 idea
