	IQueryable<TSource>^ source, 
	TSource item, 
	IEqualityComparer<TSource>^ comparer
)

Parameters

source: Type: System.LinqIQueryableTSource
The input sequence
item: Type: TSource
The value to locate in the sequence
comparer: Type: System.Collections.GenericIEqualityComparerTSource
The equality comparer to use
