Removing object from IEnumerable

I am returning a list of IEnumerable from one method. How do i remove an element from it?

i want to do something like :-

objIEnumerable.r开发者_StackOverflowemove(objCustomer)

Thanks in advance :)

IEnumerable<T> is a readonly, forward-only access collection. You cannot remove elements. You might need to cast it to the underlying type and see if it supports this operation.
