C#中Stack.Clear()方法以及示例
C#方法Stack.Clear()
Stack.Peek()方法用于从堆栈中删除所有对象。
语法:
void Stack.Clear();
参数:无
返回值:void–不返回任何内容。
示例
    declare and initialize a stack:
    Stack stk = new Stack();
    insertting elements:
    stk.Push(100);
    stk.Push(200);
    stk.Push(300);
    stk.Push(400);
    stk.Push(500);
    clearing all objects/elements:
    stk.Clear();
    
    Output:

            stk.Push(400);
            stk.Push(500);
            Console.WriteLine("Total number of objects in the stack: " + stk.Count);
            //打印堆栈元素
            Console.WriteLine("Stack elements are...");
            printStack(stk);
            //清除所有对象/元素
            stk.Clear();
            Console.WriteLine("Total number of objects in the stack: " + stk.Count);
            //按ENTER退出
            Console.ReadLine();
        }
    }
}输出结果
Total number of objects in the stack: 5 Stack elements are... 500 400 300 200 100 Total number of objects in the stack: 0
