Syntax
public static IEnumerable<TSource> Pad<TSource>(
	this IEnumerable<TSource> source,
	int width,
	Func<int, TSource> paddingSelector
)

Parameters

source
Type: System.Collections.Generic.IEnumerable<TSource>
The sequence to pad.
width
Type: System.Int32
The width/length below which to pad.
paddingSelector
Type: System.Func<Int32, TSource>
Function to calculate padding.

TSource
The type of the elements of source.

Return Value

Type: IEnumerable<TSource>
Returns a sequence that is at least as wide/long as the width/length specified by the width parameter.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable<TSource>. 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 its results.
Examples
int[] numbers = { 0, 1, 2 };
var result = numbers.Pad(5, i => -i);
The result variable, when iterated over, will yield 0, 1, 2, -3 and -4, in turn.
