Use the Take operator to return a given number of elements in a sequence and then skip over the remainder. Use the Skip operator to skip over a given number of elements in a sequence and then return the remainder.
This translation has the following limitations:. The generated query can be much more complex than the query generated for the base query on which Skip is applied. This complexity can cause decrease in performance or even a time-out.
The following example uses Take to select the first five Employees hired. Note that the collection is first sorted by HireDate. The following example uses Skip to select all except the 10 most expensive Products. The following example combines the Skip and Take methods to skip the first 50 records and then return the next Take and Skip operations are well defined only against ordered sets.
The semantics for unordered sets or multisets is undefined. When Take and Skip are chained together, all the specified ordering must be consistent. Otherwise, the results are undefined.

This method is implemented by using deferred execution. The immediate return value is an object that stores all the information that is required to perform the action. The query represented by this method is not executed until the object is enumerated either by calling its GetEnumerator method directly or by using foreach in Visual C or For Each in Visual Basic.
Take enumerates source and yields elements until count elements have been yielded or source contains no more elements. If count exceeds the number of elements in sourceall elements of source are returned. The Take and Skip methods are functional complements. Given a sequence coll and an integer nconcatenating the results of coll.
Take n and coll. Skip n yields the same sequence as coll. In Visual Basic query expression syntax, a Take clause translates to an invocation of Take. Skip to main content.
