ZipLongestExtensionZipLongestT1, T2, T3, TResult(IEnumerableT1, IEnumerableT2, IEnumerableT3, FuncT1, T2, T3, TResult) Method
Returns a projection of tuples, where each tuple contains the N-th
element from each of the argument sequences. The resulting sequence
will always be as long as the longest of input sequences where the
default value of each of the shorter sequence element types is used
for padding.

- first IEnumerableT1
- The first sequence.
- second IEnumerableT2
- The second sequence.
- third IEnumerableT3
- The third sequence.
- resultSelector FuncT1, T2, T3, TResult
-
Function to apply to each triplet of elements.
- T1
- Type of elements in first sequence.
- T2
- Type of elements in second sequence.
- T3
- Type of elements in third sequence.
- TResult
- Type of elements in result sequence.
IEnumerableTResult
A sequence that contains elements of the three input sequences,
combined by
resultSelector.
In Visual Basic and C#, you can call this method as an instance method on any object of type
IEnumerableT1. 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.
var numbers = new[] { 1, 2, 3 };
var letters = new[] { "A", "B", "C", "D" };
var chars = new[] { 'a', 'b', 'c', 'd', 'e' };
var zipped = numbers.ZipLongest(letters, chars, (n, l, c) => n + l + c);
The
zipped variable, when iterated over, will yield "1Aa",
"2Bb", "3Cc", "0Dd", "0e" in turn.
