LINQ筛选器列表按嵌套集合

// 假设有一个包含学生信息的集合
List<Student> students = new List<Student>
{
    new Student { Name = "Alice", Courses = new List<string> { "Math", "English" } },
    new Student { Name = "Bob", Courses = new List<string> { "Physics", "Chemistry" } },
    new Student { Name = "Charlie", Courses = new List<string> { "Math", "Physics" } }
};

// 使用LINQ查询表达式筛选具有特定课程的学生
var filteredStudents = from student in students
                       where student.Courses.Contains("Math")
                       select student;

// 输出筛选结果
foreach (var student in filteredStudents)
{
    Console.WriteLine(student.Name);
}

// 输出：
// Alice
// Charlie
