Request Example View Source


Type: T
The array of elements from which the n-th element should be extracted.
Type: SystemInt32
The position to look for (0 returns the smallest element, 1 the second smallest, and so on).
asc (Optional)
Type: SystemBoolean
Whether to take the smallest or the largest element. If set to false, instead of returning the smallest, the method will return the largest elements.

Type Parameters

The type for the items in the array.

Return Value

Type: T
If asc is true, returns the n-th smallest element in the array. Otherwise, returns the n-th largest.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type . 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).
As a side-effect, partially orders the collection, making sure every element smaller than the n-th smaller element are in the beginning of the array (but not necessarily in order). If you need the values that come before the n-th element to also be in order, please use the PartialT(T, Int32, Boolean) method instead.
