foreach vs LINQ .ForEach()

Question

Why does LINQ .ForEach require a List object, while the foreach statement only requires IEnumerable?

I prefer using foreach when having multiple lines and LINQ for single line statements - just for readability.

But what is preferred, and why? And why the difference?

Answer 1

There is no Linq ForEach() method. The method you are looking at is a member of List<T>.

See here for a discussion on why Linq/IEnumerable doesn't have ForEach().
