Returns a specified number of contiguous elements from the start of a sequence.
Assembly: System.Core (in System.Core.dll)
[ExtensionAttribute] public: generic<typename TSource> static IEnumerable<TSource>^ Take( IEnumerable<TSource>^ source, int count )
The type of the elements of source.
- Type: System.Collections.Generic::IEnumerable<>
The sequence to return elements from.
- Type: System::Int32
The number of elements to return.
Return ValueType: System.Collections.Generic::IEnumerable<>
An IEnumerable<T> that contains the specified number of elements from the start of the input sequence.
Usage NoteIn Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable<>. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
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.
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 source, all elements of source are returned.
If count is less than or equal to zero, source is not enumerated and an empty IEnumerable<T> is returned.
The and Skip<TSource> methods are functional complements. Given a sequence coll and an integer n, concatenating 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 .
