在C#中从堆栈中删除所有对象
要从堆栈中删除所有对象，代码如下：
示例
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.Clear();
Console.Write("Count of elements (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 Count of elements (updated) = 0
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<int> stack = new Stack<int>();
stack.Push(10);
stack.Push(20);
stack.Push(30);
stack.Push(40);
stack.Push(50);
stack.Push(60);
stack.Push(70);
stack.Push(80);
stack.Push(90);
stack.Push(100);
Console.WriteLine("Count of elements = "+stack.Count);
Console.WriteLine("Elements in Stack...");
foreach (int res in stack){
Console.WriteLine(res);
}
stack.Clear();
Console.Write("Count of elements (updated) = "+stack.Count);
}
}输出结果
这将产生以下输出-
Count of elements = 10 Elements in Stack... 100 90 80 70 60 50 40 30 20 10 Count of elements (updated) = 0
