的 Stack.Equals() C#中的方法用于检查Stack类对象是否等于另一个对象。
语法如下-
public virtual bool Equals (object ob);
上面的参数ob是与另一个对象比较的对象。
现在让我们看一个例子-
using System; using System.Collections; public class Demo { public static void Main(){ Stack stack = new Stack(); stack.Push(150); stack.Push(300); stack.Push(500); stack.Push(750); stack.Push(1000); stack.Push(1250); stack.Push(1500); stack.Push(2000); stack.Push(2500); Console.WriteLine("堆叠元素..."); foreach(int val in stack){ Console.WriteLine(val); } Console.WriteLine("Count of elements = "+stack.Count); stack.Push(3000); stack.Push(3500); stack.Push(4000); Console.WriteLine("\n堆叠元素...updated"); foreach(int val in stack){ Console.WriteLine(val); } Console.WriteLine("\nCount of elements (updated) = "+stack.Count); Stack stack2 = (Stack)stack.Clone(); Console.WriteLine("\n堆叠元素...cloned"); foreach(int val in stack2){ Console.WriteLine(val); } Console.Write("克隆堆栈中的元素计数 (updated) = "+stack2.Count); Console.WriteLine("\nstack是否相等? = "+stack.Equals(stack2)); } }
输出结果
这将产生以下输出-
堆叠元素... 2500 2000 1500 1250 1000 750 500 300 150 Count of elements = 9 堆叠元素...updated 4000 3500 3000 2500 2000 1500 1250 1000 750 500 300 150 Count of elements (updated) = 12 堆叠元素...cloned 4000 3500 3000 2500 2000 1500 1250 1000 750 500 300 150 克隆堆栈中的元素计数 (updated) = 12 stack是否相等? = False
现在让我们来看另一个示例-
using System; using System.Collections; public class Demo { public static void Main(){ Stack stack1 = new Stack(); stack1.Push(150); stack1.Push(300); stack1.Push(500); stack1.Push(750); stack1.Push(1000); Console.WriteLine("Stack1元素..."); foreach(int val in stack1){ Console.WriteLine(val); } Stack stack2 = new Stack(); stack2.Push(350); stack2.Push(400); stack2.Push(500); stack2.Push(850); stack2.Push(900); Console.WriteLine("Stack2元素..."); foreach(int val in stack2){ Console.WriteLine(val); } Console.WriteLine("\nstack是否相等? = "+stack1.Equals(stack2)); } }
输出结果
这将产生以下输出-
Stack1元素... 1000 750 500 300 150 Stack2元素... 900 850 500 400 350 stack是否相等? = False
