它们最大的区别在于 Class 是引用类型, Struct 是值类型.引用类型 (heap) vs 值类型 (stack) 定义是差不多的, 可以有 property, method, constructor 等等 publicstructDimensionStruct {publicintWidth {get;set; }publicintHeight {get;set; } }publicclassDimensionClass {publicintWidth {get;set; }publicin...
BACK: Push the current page on the top of the forward stack. Pop the page from the top of the backward stack, making it the new current page. If the backward stack is empty, the command is ignored. FORWARD: Push the current page on the top of the backward stack. Pop the page from...

结构体实例的内存在栈(stack)上进行分配,所占用的内存随声明它的类型或方法一起回收。这就是在赋值时要复制结构体的一个原因。相比之下,类实例的内存在堆(heap)上进行分配,当对类实例的所有引用都超出范围时,为该类实例分配的内存将由公共语言运行时自动回收(垃圾回收)。
If you exit a function that declares CDaoRecordset or CDaoDatabase objects on the stack, the database is closed, any unsaved changes are lost, all pending transactions are rolled back, and any pending edits to your data are lost.Caution If you try to close a database object while any ...
