Parameters
- source
- Type: System.Collections.GenericIEnumerableTSource
The source sequence. - count
- Type: SystemInt32
Number of (maximum) elements to return. - keySelector
- Type: SystemFuncTSource, TKey
A function to extract a key from an element. - comparer
- Type: System.Collections.GenericIComparerTKey
A IComparerT to compare elements.
Type Parameters
- TSource
- Type of elements in the sequence.
- TKey

Return Value
Type:
IEnumerableTSourceA sequence containing at most top
count
elements from source, in ascending order of their keys.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type
IEnumerableTSource. 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).
Remarks
This operator uses deferred execution and streams it results.
