在c#中对格式如下的项目进行自定义排序

public class Project
{
    public string Name { get; set; }
    public int Priority { get; set; }
    public DateTime StartDate { get; set; }
}

List<Project> projects = new List<Project>
{
    new Project { Name = "Project A", Priority = 2, StartDate = new DateTime(2022, 1, 1) },
    new Project { Name = "Project B", Priority = 1, StartDate = new DateTime(2022, 2, 1) },
    new Project { Name = "Project C", Priority = 3, StartDate = new DateTime(2022, 3, 1) }
};

// 自定义排序规则
projects.Sort((p1, p2) =>
{
    // 根据优先级进行排序
    int priorityComparison = p1.Priority.CompareTo(p2.Priority);
    if (priorityComparison != 0)
    {
        return priorityComparison;
    }

    // 如果优先级相同，则根据开始日期进行排序
    return p1.StartDate.CompareTo(p2.StartDate);
});

// 输出排序结果
foreach (var project in projects)
{
    Console.WriteLine($"Name: {project.Name}, Priority: {project.Priority}, Start Date: {project.StartDate}");
}
