EquiZipExtensionEquiZipT1, T2, T3, TResult Method (IEnumerableT1, IEnumerableT2, IEnumerableT3, FuncT1, T2, T3, TResult) |
Returns a projection of tuples, where each tuple contains the N-th
element from each of the argument sequences.

Parameters
- first
- Type: System.Collections.GenericIEnumerableT1
The first sequence. - second
- Type: System.Collections.GenericIEnumerableT2
The second sequence. - third
- Type: System.Collections.GenericIEnumerableT3
The third sequence. - resultSelector
- Type: SystemFuncT1, T2, T3, TResult
Function to apply to each triplet of elements.
Type Parameters
- 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.
Return Value
Type:
IEnumerableTResult
A sequence that contains elements of the three input sequences,
combined by
resultSelector.
Usage Note
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).
Remarks If the three input sequences are of different lengths then
InvalidOperationException is thrown.
This operator uses deferred execution and streams its results.
Examples var numbers = new[] { 1, 2, 3, 4 };
var letters = new[] { "A", "B", "C", "D" };
var chars = new[] { 'a', 'b', 'c', 'd' };
var zipped = numbers.EquiZip(letters, chars, (n, l, c) => n + l + c);
The
zipped variable, when iterated over, will yield "1Aa",
"2Bb", "3Cc", "4Dd" in turn.
