How to compare two Dictionaries in C#

Question

I have two Generic Dictionaries.Both have same keys.But values can be different.I want to compare 2nd dictionary with 1st dictionary .If there are differences between values

Answer 1

Assuming both dictionaries have the same keys, the simplest way is

var result = a.Except(b).ToDictionary(x => x.Key, x => x.Value);

EDIT

Note that a.Except(b) gives a different result from b.Except(a):

a.Except(b): Price     20
b.Except(a): Price     40
