Question

Checking equality on unordered lists can be done with Intersect, but how would you compare ordered lists with LINQ? The expression should return true if both sequences have the same elements in the same order.

Thanks

Answer 1

a.SequenceEqual(b);

From the documentation:

Returns true if the two source
sequences are of equal length and
their corresponding elements are equal
according to the default equality
comparer for their type; otherwise,
false.
