error C2019: expected preprocessor directive, found 'character'中文对照:(编译错误)期待预处理命令,但有无
预处理指令(preprocessor directive)指示编译器如何处理源代码 作用是为编译器添加额外的编译信息 预处理器在编译时调用的指令,类似于条件运算表达式,不过是在编译时调用,不是在运行时调用,可以决定哪些语句进行编译 注意: C#中本质上没有预处理程序,实际上是由编译器处理的,C/C++有实际预处理阶段 预处理...

* The header file, when created, is given the same timestamp as the type library. * When #import is processed, the compiler first checks if the header exists and is up to date. If yes, then it does not need to be re-created. The #import directive also participates in minimal rebuild...
Although the compiler doesn't have a separate preprocessor, the directives described in this section are processed as if there were one. You use them to help in conditional compilation. Unlike C and C++ directives, you can't use these directives to create macros. A preprocessor directive must ...
A#regionblock must be terminated with an#endregiondirective. A#regionblock can't overlap with an#ifblock. However, a#regionblock can be nested in an#ifblock, and an#ifblock can be nested in a#regionblock. Error and warning information ...

控制流语句中的条件表达式是在运行时求值的。而C#预处理器指令是在编译时调用的。预处理器指令(preprocessor directive)告诉C#编译器要编译哪些代码,并指出如何处理特定的错误和警告。C#预处理器指令还可以告诉C#编辑器有关代码组织的信息。 语言对比:C++ —— 预处理 ...
