C# RavenDB映射缩减函数
我正在尝试为索引编写一个RavenDB Map Reduce函数，以整理来自一组域模型的信息。我无法填充所有的结果字段，但我已经花了一天左右的时间，并且遗漏了一些我认为基本的东西 这是：C# RavenDB映射缩减函数,c#,indexing,mapreduce,ravendb,C#,Indexing,Mapreduce,Ravendb,我正在尝试为索引编写一个RavenDB Map Reduce函数，以整理来自一组域模型的信息。我无法填充所有的结果字段，但我已经花了一天左右的时间，并且遗漏了一些我认为基本的东西 这是： public class All_Groups : AbstractMultiMapIndexCreationTask<All_Groups.Result> { public class Result { public string Type { get; set;

我一直在为这个扯我的头发，它就快到了，但我需要一些新鲜的眼睛，有人吗
干杯
哈米什 结果是它比我在上面做的要简单一点。我试图解决的问题是：
Approt是我的应用程序和域模型的根级别的组。可以是组织、团队或项目的组可以被链接为Approt的子级，或者按照组织拥有团队、团队拥有项目的顺序链接
还有一些用户项目作为Approt的关联存在
我需要统计每个项目中的所有成员，以及每个项目中的子项目，这就是下面Map Reduce函数使用域模型对象GroupAssociation所做的
有关更多详细信息，请参见上面的链接域模型图：
