导读：我必须汇总两个词典. 码： private Dictionary int,aor.PhysicalObject agents;private Dictionary int,aor.PhysicalObject objects;agents = (from a in log .InitialState .Agents .Agent select a) .ToDictionary(d = Convert.ToInt32(d.id),d = d as aor

我必须汇总两个词典.

码：

private Dictionary <int,aor.PhysicalObject> agents;
private Dictionary <int,aor.PhysicalObject> objects;

agents = (from a in log
                   .InitialState
                   .Agents
                   .Agent 
         select a)
         .ToDictionary(d => Convert.ToInt32(d.id),d => d as aor.PhysicalObject);

objects = (from o in log
                     .InitialState
                     .Objects
                     .Object 
           select o)
           .ToDictionary(d => Convert.ToInt32(d.id),d => d as aor.PhysicalObject);

我现在想要的是一本字典,其中包含代理商的所有元素和对象字典.

您可能认为重复键可能存在问题,但每个键(id)都是唯一的,因此没有问题.

如果只通过一个LINQ查询完成此任务,那将非常酷.

解决方法

如果密钥是唯一的,您可以将两个字典组合如下：

//码

private Dictionary <int,aor.PhysicalObject> merger;

merger = Enumerable
         .Concat(  from a in log
                             .InitialState
                             .Agents
                             .Agent
                    select a,from o in log
                              .InitialState
                              .Objects
                              .Object  
                     select o
                ).ToDictionary(d => Convert.ToInt32(d.id),d => d as aor.PhysicalObject);
