類型參數

TSource

可查詢序列中元素的類型。The type of the elements in the queryable sequence.

參數

source
IQueryable<TSource>

可查詢的序列。A queryable sequence.

count
Int32

要從可查詢序列末端移除的元素數。The number of elements to omit from the end of the queryable sequence.

傳回

IQueryable<TSource>

新的可查詢序列，其包含減去可查詢序列末端 count 元素的所有 source 元素。A new queryable sequence that contains the elements from source minus count elements from the end of the queryable sequence.

例外狀況
