Difference between Extension methods and Methods in C#

Question

What is the difference between Extension Methods and Methods in C#?

Answer 1

I think what you are really looking for is the difference between Static and Instance Methods

At the end of the day Extension methods are some nice compiler magic and syntactic sugar that allow you to invoke a Static method as though it were a method defined on that particular class instance. However, it is NOT an instance method, as the instance of that particular class must be passed into the function.
