Queryable.Except<'TSource> Method (IQueryable<'TSource>, IEnumerable<'TSource>)
Produces the set difference of two sequences by using the default equality comparer to compare values.
Assembly: System.Core (in System.Core.dll)
static member Except<'TSource> : source1:IQueryable<'TSource> * source2:IEnumerable<'TSource> -> IQueryable<'TSource>
An IQueryable<'T> whose elements that are not also in source2 will be returned.
Return ValueType: System.Linq.IQueryable<'TSource>
An IQueryable<'T> that contains the set difference of the two sequences.
The type of the elements of the input sequences.
The MethodCallExpression that represents calling itself as a constructed generic method. It then passes the MethodCallExpression to the CreateQuery<'TElement>(Expression) method of the IQueryProvider represented by the Provider property of thesource1 parameter.method generates a
The query behavior that occurs as a result of executing an expression tree that represents callingdepends on the implementation of the type of the source1 parameter. The expected behavior is that all the elements in source1 are returned except for those that are also in source2.
