source: Type: System.Collections.GenericIListT
IList to search
match: Type: SystemPredicateT
The PredicateT delegate that defines the conditions of the element to search for.

Type Parameters

T: [Missing <typeparam name="T"/> documentation for "M:DHI.Mike1D.Generic.GenericExtensions.FindIndex``1(System.Collections.Generic.IList{``0},System.Predicate{``0})"]
