C# 和匿名对象数组

使用C#和匿名对象数组进行数据处理

csharp
var students = new[] {
    new { Name = "张三", Age = 18, Grade = "一年级" },
    new { Name = "李四", Age = 19, Grade = "二年级" },
    new { Name = "王五", Age = 20, Grade = "三年级" }
};
foreach (var student in students)
{
    Console.WriteLine($"姓名：{student.Name}，年龄：{student.Age}，年级：{student.Grade}");
}

csharp
var adults = students.Where(s => s.Age >= 18);
var sortedStudents = students.OrderBy(s => s.Age);
var groupedStudents = students.GroupBy(s => s.Grade);
foreach (var student in adults)
{
    Console.WriteLine($"成年学生：{student.Name}");
}
foreach (var student in sortedStudents)
{
    Console.WriteLine($"按年龄排序：{student.Name}");
}
foreach (var group in groupedStudents)
{
    Console.WriteLine($"年级：{group.Key}");
    foreach (var student in group)
    {
        Console.WriteLine($"学生：{student.Name}");
    }
}
