如何将LINQ写入对象此代码的等效代码

// 假设有一个名为Student的类，包含属性Name和Age
List<Student> students = new List<Student>
{
    new Student { Name = "Alice", Age = 20 },
    new Student { Name = "Bob", Age = 22 },
    new Student { Name = "Charlie", Age = 18 }
};

// 使用LINQ查询年龄大于等于20岁的学生
var query = from student in students
            where student.Age >= 20
            select student;

// 将查询结果转换为列表
List<Student> result = query.ToList();

List<Student> students = new List<Student>
{
    new Student { Name = "Alice", Age = 20 },
    new Student { Name = "Bob", Age = 22 },
    new Student { Name = "Charlie", Age = 18 }
};

// 使用foreach循环和条件语句查询年龄大于等于20岁的学生
List<Student> result = new List<Student>();
foreach (Student student in students)
{
    if (student.Age >= 20)
    {
        result.Add(student);
    }
}
