The dot operator specifies a method or class or other member within a package , or specifies a sub - package 点运算符指定包中的一个方法或类或其他成员，或指定一个子包。
Instances , which means you must use the dot operator to retrieve the actual data stored in the cookie through the object s 特性使用点运算符来检索储存在cookie中的实际数据。
When you enter a . net framework type into the code editor , and then type the dot operator , intellisense displays a list box that contains the members of that type Net framework类型输入代码编辑器，再键入点运算符( . ) ， intellisense将显示包含该类型各成员的列表框。
For example , if the elements of an array are themselves objects , the bracket operator can be used to retrieve an element of the array and be combined with the dot operator to retrieve one of the element s properties for instance , 例如，如果数组的元素本身是对象，则可以使用方括号运算符来检索该数组的元素，并结合点运算符来检索该元素的一个特性（例如
