FillForwardExtensionFillForwardT(IEnumerableT, FuncT, Boolean, FuncT, T, T) Method
Returns a sequence with each missing element in the source replaced
with one based on the previous non-missing element seen in that
sequence. Additional parameters specify two functions, one used to
determine if an element is considered missing or not and another
to provide the replacement for the missing element.

- source IEnumerableT
- The source sequence.
- predicate FuncT, Boolean
- The function used to determine if
an element in the sequence is considered missing.
- fillSelector FuncT, T, T
- The function used to produce the element
that will replace the missing one. Its first argument receives the
current element considered missing while the second argument
receives the previous non-missing element.
- T
- Type of the elements in the source sequence.
IEnumerableT
An
IEnumerableT with missing values replaced.
In Visual Basic and C#, you can call this method as an instance method on any object of type
IEnumerableT. 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 uses deferred execution semantics and streams its
results. If elements are missing at the start of the sequence then
they remain missing.
