Namespace: Altaxo.CollectionsAssembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3179.0 (4.8.3179.0)
Syntax public static IEnumerable<TResult> JoinConditional<T1, T2, TResult>(
this IEnumerable<T1> seq1,
IEnumerable<T2> seq2,
Func<T1, T2, bool> Condition,
Func<T1, T2, TResult> CreateResult
)
Parameters
- seq1 IEnumerableT1
- The first sequence.
- seq2 IEnumerableT2
- The second sequence.
- Condition FuncT1, T2, Boolean
- A condition that is evaluated for each pair of (T1, T2). Only if the return value is true, the pair (T1, T2) is put into the output sequence.
- CreateResult FuncT1, T2, TResult
- A function that takes a pair of T1 and T2 as parameters, and returns the result.
Type Parameters
- T1
- The element type of the 1st sequence.
- T2
- The element type of the 2nd sequence.
- TResult
- The element type of the resulting sequence.
Return Value
IEnumerableTResultThe resulting sequence of with elements of type TResult.
Usage Note
