I would like to split my array that consists of objects in arrays, grouping them by some property of the type (let's say
string Group {get; set;}
).
At the beginning I have
IEnumerable<T> array.
Then I would like to get
IEnumerable<IEnumerable<T>> array.
Of course, I can do it without LINQ, but it will look too ugly and verbose.
array.GroupBy(item => item.Group)
this will give you IEnumerable<IGrouping<string, YourType>>. The IGrouping<string, YourType> extends IEnumerble<YourType> with Key, which will be the value of Group property in your example:
foreach (var g in array.GroupBy(item => item.Group))
{
Console.WriteLine("Group='{0}', {1} items", g.Key, g.Count());
}
