LINQ query code for complex merging of data.
- by Stacey
I've posted this before, but I worded it poorly. I'm trying again with a more well thought out structure.
Re-writing this a bit to make it more clear. I have the following code and I am trying to figure out the shorter linq expression to do it 'inline'. Please examine the "Run()" method near the bottom. I am attempting to understand how to join two dictionaries together based on a matching identifier in one of the objects - so that I can use the query in this sort of syntax.
var selected = from a in items.List()
// etc. etc.
select a;
This is my class structure. The Run() method is what I am trying to simplify. I basically need to do this conversion inline in a couple of places, and I wanted to simplify it a great deal so that I can define it more 'cleanly'.
class TModel
{
public Guid Id { get; set; }
}
class TModels : List<TModel>
{
}
class TValue
{
}
class TStorage
{
public Dictionary<Guid, TValue> Items { get; set; }
}
class TArranged
{
public Dictionary<TModel, TValue> Items { get; set; }
}
static class Repository
{
static public TItem Single<TItem, TCollection>(Predicate<TItem> expression)
{
return default(TItem); // access logic.
}
}
class Sample
{
public void Run()
{
TStorage tStorage = new TStorage();
// access tStorage logic here.
Dictionary<TModel, TValue> d = new Dictionary<TModel, TValue>();
foreach (KeyValuePair<Guid, TValue> kv in tStorage.Items)
{
d.Add(Repository.Single<TModel, TModels>(m => m.Id == kv.Key),kv.Value);
}
}
}
