Parameters

source  IEnumerableTSource

An enumeration over which to find the majority element.

defaultValue  TSource

Default value to return if no item represents the majority.

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.
