法律研究C# 中的 Stack.GetEnumerator() 方法
C# 中的 Stack.GetEnumerator() 方法用于为 Stack 返回一个 IEnumerator。
语法
语法如下 −
public virtual System.Collections.IEnumerator GetEnumerator ();
示例
接下来我们看一个示例 −
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 elements...");
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);
IEnumerator demoEnum = stack2.GetEnumerator();
Console.WriteLine("Stack2 elements...");
while (demoEnum.MoveNext()) {
Console.WriteLine(demoEnum.Current);
}
Console.WriteLine("
Are both the stacks equal? = "+stack1.Equals(stack2));
}
}输出
它会生成以下输出 −
Stack1 elements... 1000 750 500 300 150 Stack2 elements... 900 850 500 400 350 Are both the stacks equal? = False
示例
现在我们看另一个示例 −
using System;
using System.Collections;
public class Demo {
public static void Main(){
Stack stack = new Stack();
stack.Push("Inspiron");
stack.Push("Alienware");
stack.Push("Projectors");
stack.Push("Monitors");
stack.Push("XPS");
stack.Push("Laptop");
stack.Push("Notebook");
Console.WriteLine("Stack elements...");
foreach(string val in stack){
Console.WriteLine(val);
}
Console.WriteLine("Count of elements = "+stack.Count);
Console.WriteLine("Element Speakers is the stack? = "+stack.Contains("Speakers"));
stack.Push("Headphone");
stack.Push("Keyboard");
stack.Push("Earphone");
Console.WriteLine("
Stack elements...updated");
foreach(string val in stack){
Console.WriteLine(val);
}
Console.WriteLine("Count of elements (updated) = "+stack.Count);
Console.WriteLine("
Element Alienware is the stack? = "+stack.Contains("Alienware"));
Stack stack2 = (Stack)stack.Clone();
Console.WriteLine("
Stack elements...cloned");
IEnumerator demoEnum = stack2.GetEnumerator();
while (demoEnum.MoveNext()) {
Console.WriteLine(demoEnum.Current);
}
Console.WriteLine("Count of elements (updated) = "+stack.Count);
}
}输出
它会生成以下输出 −
Stack elements... Notebook Laptop XPS Monitors Projectors Alienware Inspiron Count of elements = 7 Element Speakers is the stack? = False Stack elements...updated Earphone Keyboard Headphone Notebook Laptop XPS Monitors Projectors Alienware Inspiron Count of elements (updated) = 10 Element Alienware is the stack? = True Stack elements...cloned Earphone Keyboard Headphone Notebook Laptop XPS Monitors Projectors Alienware Inspiron Count of elements (updated) = 10
