如何合并2个词典

Question

我必须汇总两个词典。

代码：

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＆amp;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。

如果只能通过一个LINQ查询完成此任务，那将非常酷。

Answer 1

如果密钥是唯一的，您可以将两个字典组合如下：

//代码

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);
