IGrouping and Casting in Linq
- by FiveTools
I have the following query:
var groupCats =
from g in groups
group g by g.Value into grouped
select new
{
GroupCategory = grouped.Key,
Categories = GetCategories(grouped.Key, child)
};
This works fine. In the anonymous type returned GroupCategory is a string, and Categories are an Enumerable - what is the proper way to declare this instead of using 'var'?
I tried:
IGrouping<string,string> groupCats =
from g in groups
group g by g.Value into grouped
select new
{
GroupCategory = grouped.Key,
Categories = GetCategories(grouped.Key, child)
};
and
IGrouping<string,Enumerable<string>> groupCats =
from g in groups
group g by g.Value into grouped
select new
{
GroupCategory = grouped.Key,
Categories = GetCategories(grouped.Key, child)
};
In both instances I get:
Cannot implicity convert type....An explicit conversion exists (are you missing a cast)
How do I cast this?
