Public Function ExceptBy(Of TSource, TKey) (first As IEnumerable(Of TSource), second As IEnumerable(Of TKey), keySelector As Func(Of TSource, TKey)) As IEnumerable(Of TSource)Type Parameters
- TSource
The type of the elements of the input sequence.
- TKey
The type of key to identify elements by.
Parameters
- first
- IEnumerable<TSource>
An IEnumerable<T> whose keys that are not also in second will be returned.
- second
- IEnumerable<TKey>
An IEnumerable<T> whose keys that also occur in the first sequence will cause those elements to be removed from the returned sequence.
- keySelector
- Func<TSource,TKey>
A function to extract the key for each element.
Returns
A sequence that contains the set difference of the elements of two sequences.
