叠加。C# 中的计数属性
原文:https://www . geesforgeks . org/stack-count-property-in-c-sharp/
该方法(属于系统。Collections 命名空间)用于获取堆栈中包含的元素数量。容量是堆栈可以存储的元素数量，计数是堆栈中实际存在的元素数量。容量始终大于或等于计数。检索该属性的值是一个 O(1)操作。
语法:
public virtual int Count { get; }
返回值:返回类型为系统的堆栈中包含的元素数量。Int32 。
以下程序说明了上述属性的使用:
例 1:
// C# code illustrate the
// Stack.Count Property
using System;
using System.Collections;
class GFG {
// Driver code
public static void Main()
{
// Creating a Stack
Stack myStack = new Stack();
// Inserting the elements into the Stack
myStack.Push("Chandigarh");
myStack.Push("Delhi");
myStack.Push("Noida");
myStack.Push("Himachal");
myStack.Push("Punjab");
myStack.Push("Jammu");
// Displaying the count of elements
// contained in the Stack
Console.Write("Total number of elements"+
" in the Stack are : ");
Console.WriteLine(myStack.Count);
}
}
Output:
Total number of elements in the Stack are : 6
例 2:
// C# code illustrate the
// Stack.Count Property
using System;
using System.Collections;
class GFG {
// Driver code
public static void Main()
{
// Creating a Stack
Stack myStack = new Stack();
// Displaying the count of elements
// contained in the Stack
Console.Write("Total number of elements"+
" in the Stack are : ");
// The function should return 0
// as the Stack is empty and it
// doesn't contain any element
Console.WriteLine(myStack.Count);
}
}
Output:
Total number of elements in the Stack are : 0
