IntersectBy Operator #63

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Similar to DistinctBy but with the functionality of Intersect 

so Something like this:

var emails = GetAllEmails();
var uniqueEmails = emails.DistinctBy(x => x.Email).ToList();
var duplicates = emails.IntersectBy(uniqueEmails, x => x.EmailAddress);

Thanks
