Introduction

The Skip operator skips a given number of elements from a sequence and then yields the remainder of the sequence.

Edit

Method Signatures

public static IEnumerable<TSource> Skip<TSource>(
    this IEnumerable<TSource> source, 
    int count)



Edit

Exceptions

Throw an ArgumentNullException if source is null.


Edit

Pseudo-code

If source is null, throw an ArgumentNullException.
Iterate the source sequence.
If count > 0, decrement count by one.
If count <= 0.
Resume iterating source from the point we skipped to.
Return the current element. Resume execution from this point when the next element is requested.

Note: If count < 0, all records are returned.
Note: If count is greater than the number of elements in source, then no elements are returned.


Edit

Loop Count

Initially, count number of records are enumerated over with no result returned. This operator implements the standard deferred execution iterator pattern. This means, no looping will occur until the result is iterated over.
