static member Pad :

paddingSelector : Func<int, 'TSource> -> IEnumerable<'TSource>
- source IEnumerableTSource
- The sequence to pad.
- width Int32
- The width/length below which to pad.
- paddingSelector FuncInt32, TSource
- Function to calculate padding.
- TSource
- The type of the elements of source.
IEnumerableTSource
Returns a sequence that is at least as wide/long as the width/length
specified by the
width parameter.
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).
This operator uses deferred execution and streams its results.
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.
