Possible Duplicate: Extension Method Performance Will I face performance issues when I´m using extension

Possible Duplicate:
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.

    No you will not.

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