Method DeferredSequenceEqual

DeferredSequenceEqual<TSource>(IQueryable<TSource>, IEnumerable<TSource>)

This method is the deferred implementation of the extension method . In EF some linq operations are performed on the client end instead of the server. Therefore, if we use the regular method it will cache the data from the database before performing the actual "SequenceEqual" operation. To cater to this, we provide with a deferred implementation that delays the caching so that only the result can be cached.

Declaration
public static QueryDeferred<bool> DeferredSequenceEqual<TSource>(this IQueryable<TSource> source1, IEnumerable<TSource> source2)
Parameters
Type Name Description
IQueryable<TSource> source1

An System.Linq.IQueryable`1 whose elements to compare to those of source2.
IEnumerable<TSource> source2

An System.Collections.Generic.IEnumerable`1 whose elements to compare to those of the first sequence.
Returns
Type Description
QueryDeferred<System.Boolean>

true if the two source sequences are of equal length and their corresponding elements compare equal; otherwise, false.
Type Parameters
Name Description
TSource

The type of the elements of the input sequences.
