This is a great article on using DISTINCT operator with LINQ.

This article is not so great, it flies over casual things.

Why dont you talk about Distinct and the IEqualityComparer that raise an exception if the linq select manages a class object and not a basic type int, string...

I'm talking about the <Unsupported overload used for query operator 'Distinct'.>

class MyClassComparer : IEqualityComparer<MyClass> ...

class MyClass ...

var result = (from e in DC.MyClass

where .....

select e).Distinct( new MyClassComparer )....

This sample always generates the exception not supported.

Great linq !!! Maybe, maybe not

Thanks a lot for this post, very helpful especially when you described why Distinct has to be called as opposed to being part of the sugar syntax.

although this article is fine. but it not give any information about Distinct() when using with the generic lists and we have to select the records from those lists not just one item. what we have to do then??? what linq provides us then because it supports only the primitive types like int,string,long etc,,

could any one give me suggestion over this???
