asp.netC# 中的静态变量

ASP.NET是一种用于构建Web应用程序的开发框架，而C#是用于编写ASP.NET应用程序的主要编程语言。在ASP.NET/C#中，静态变量是一种特殊类型的变量，它们存储在内存的静态数据区域，并且在整个应用程序的生命周期内保持不变。

public class Student
{
    public string Name { get; set; }
    public int Age { get; set; }
    public static int TotalCount { get; set; }
    public Student(string name, int age)
    {
        Name = name;
        Age = age;
        TotalCount++;
    }
    public static void RemoveStudent()
    {
        TotalCount--;
    }
}
public class Program
{
    public static void Main(string[] args)
    {
        Student student1 = new Student("Alice", 18);
        Student student2 = new Student("Bob", 19);
        Student student3 = new Student("Charlie", 20);
        Console.WriteLine("Total number of students: " + Student.TotalCount);
        Student.RemoveStudent();
        Console.WriteLine("Total number of students after removing one: " + Student.TotalCount);
    }
