Extension Methods: Performance issue when using too much? [duplicate]

Question

Extension Method Performance

Will I face performance issues when I´m using extension methods too heavy in any way?

Just an example:

Lets say I´ve 100 extension methods on the type string and a business object that has 50 string properties. Now I create a collection of this business object, maybe 500 items?

Do these extension methods on string have any impact to RAM, CPU, ...?!

I really like extension methods but I´d like to know if there is a limitation concerning its usage.

Answer 1

No you will not.

Extension methods are just normal static methods with some syntactic sugar. Use them as much as you want :)

Answer 2

You might slow intellisense down in the IDE - and possibly make the intellisense lists a bit unwieldy, but it won't have any impact on the execution of the code itself over any other static method.
