C#中,async关键字到底起什么作用? 标记了async,函数里就可以用await,return的语义也会发生变化,返回类型也必须是Task或者Task<T>。所以这就是个语法而已,不要去对async钻牛角尖。你这个问题就像为什么只有函数里面可以写语句而类里面不行一样。 如果你用了async但是没用await,你也是创造了一个Task类的构造函数,仅...
c、静态数据成员因为程序一开始运行就必需存在,所以其初始化的最佳位置在类的内部实现。 C、特点 a、对相于 public,protected,private 关键字的影响它和普通数据成员一样, b、因为其空间在全局数据区分配,属于所有本类的对象共享,所以,它不属于特定的类对象,在没产生类对象时其作用域就可见,即在没有产生类的实例...

publicclassMyBaseC{publicstructMyStruct {publicstaticintx =100; } } 若要引用static成员x,除非可从相同范围访问该成员,否则请使用完全限定的名称MyBaseC.MyStruct.x: C# Console.WriteLine(MyBaseC.MyStruct.x); 尽管类的实例包含该类的所有实例字段的单独副本,但每个static字段只有一个副本。
Rust编译器的静态求解器会在编译期把这个static变量的值给算出来。但是,现实就是,Rust的静态求解器对于有多级的变量需要new的情况,也就是一个struct里面的另一个变量也需要new出来的情况的处理是很糟糕的。尽管我们肉眼就能看出来这个值是可以在编译期被确定的,但是可惜的是,Rust的编译器会告诉我们,这个不能在编译...
