如何使用全局#define让所有文件都知道？ [英] how to use global #define to let all file know?

问题描述

亲爱的所有人，

是否可以定义"＃define"最上层文件中的语句和其他文件导入此文件进行条件编译？

示例，

#define READ_FUNCTION_SUPPORTED在FunctionSwitch中定义.cs

在语句对中有一个代码块"#if READ_FUNCTION_SUPPORTED ....＃end"在UI.cs文件中

和 在语句对中有一个代码块"#if READ_FUNCTION_SUPPORTED ....＃end"在Business.cs文件中

谢谢和最好的问候，

E-John

>是否可以定义"#define""最上层文件中的语句和该文件是否由其他文件导入以进行条件编译？

您可以通过命令行传递定义，或者在VS IDE中传递C＃项目，使用项目的Build，条件编译

符号设置。见这里：

Dear All,

Is it possible to define the "#define" statement in up-most file and this file is imported by other files to do conditional compiling?

Example,

#define READ_FUNCTION_SUPPORTED is defined in FunctionSwitch.cs

there is a code block inside the statement pair "#if READ_FUNCTION_SUPPORTED ....#end" in UI.cs file

and there is a code block inside the statement pair "#if READ_FUNCTION_SUPPORTED ....#end" in Business.cs file

Thanks and Best regards,

E-John

You can pass definitions via the command line, or in the VS IDE for a C# project, use the project's Build, conditional compilation
symbols setting. See here:
