View SourceParameters
- source IEnumerableTSource
- An enumeration over which to find the majority element.
- keySelector FuncTSource, TKey
- A delegate that takes an object and produces the key for comparison.
- forwardSearch Boolean (Optional)
- true to search forward in source; otherwise false to search backwards.
- comparer IEqualityComparerTKey (Optional)
- The IEqualityComparerT implementation to use when comparing keys, or null to use the default comparer for the type of the key.
Type Parameters
- TSource
- Type of elements in the source.
- TKey
- The generic type of the objects to be compared.
Return Value
TSourceThe minority value in the collection.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type
IEnumerableTSource. When you use instance method syntax to call this method, omit the first parameter. For more information, see
Extension Methods (Visual Basic) or
