在C#中的堆栈顶部插入一个对象
要在堆栈顶部插入对象，代码如下-
示例
using System;
using System.Collections.Generic;
public class Demo {
public static void Main() {
Stack<int> stack = new Stack<int>();
stack.Push(100);
stack.Push(150);
stack.Push(175);
stack.Push(200);
stack.Push(225);
stack.Push(250);
Console.WriteLine("堆栈中的元素：");
foreach(var val in stack) {
Console.WriteLine(val);
}
Console.WriteLine("Count of elements in the Stack = "+stack.Count);
Console.WriteLine("Does Stack has the element 400?= "+stack.Contains(400));
stack.Push(300);
stack.Push(400);
stack.Push(450);
stack.Push(500);
Console.WriteLine("Elements in the Stack... (UPDATED)");
foreach(var val in stack) {
Console.WriteLine(val);
}
Console.WriteLine("Count of elements in the Stack (UPDATED) = "+stack.Count);
}
}输出结果
这将产生以下输出-
堆栈中的元素： 250 225 200 175 150 100 Count of elements in the Stack = 6 Does Stack has the element 400?= False Elements in the Stack... (UPDATED) 500 450 400 300 250 225 200 175 150 100 Count of elements in the Stack (UPDATED) = 10
示例
让我们看另一个例子-
using System;
using System.Collections.Generic;
public class Demo {
public static void Main() {
Stack<string> stack = new Stack<string>();
stack.Push("A");
stack.Push("B");
stack.Push("C");
stack.Push("D");
stack.Push("E");
stack.Push("F");
stack.Push("G");
stack.Push("H");
Console.WriteLine("Count of elements = "+stack.Count);
Console.WriteLine("Elements in Stack...");
foreach (string res in stack) {
Console.WriteLine(res);
}
stack.Push("M");
Console.WriteLine("Elements in the Stack... (UPDATED)");
foreach(var val in stack) {
Console.WriteLine(val);
}
Console.WriteLine("Count of elements in the Stack (UPDATED) = "+stack.Count);
}
}输出结果
这将产生以下输出-
Count of elements = 8 Elements in Stack... H G F E D C B A Elements in the Stack... (UPDATED) M H G F E D C B A Count of elements in the Stack (UPDATED) = 9
