In terms of scope and extent, static variables have extent the entire run of the program, but may have more limited scope. A basic distinction is between a static global variable, which is in scope throughout the program, and a static local variable, which is only in scope within a funct...
// you don't need to capture a global variable [] {returnx; }; } 但如果是局部变量,由于它的存储时期为 automatic,就必须捕获才能使用: intmain{ intx =42; // you have to capture a local variable [&x] {returnx; }; } 但如果使用 static 修饰该局部变量,就无需再进行捕获: ...

未使用的區域變數: '<localvariablename>' 使用請用命令列選項 '' 或適當的專案設定取代 '<parameter>' 'Using' 之後必須搭配相對應的 'End Using' 型別'<typename>' 的 'Using' 運算子必須實作 System.IDisposable 'Using' 資源變數必須擁有明確的初始設定 'Using' 資源變數型別不能是陣列型別 即時運算視窗...
