The Queryable type exposes the following members.

  NameDescription
Public method Static member Aggregate Overloaded. Applies an accumulator function over a sequence.
Public method Static member All<TSource> Determines whether all the elements of a sequence satisfy a condition.
Public method Static member Any Overloaded. Determines whether any element of an IQueryable<T> sequence exists or satisfies a condition.
Public method Static member AsQueryable Overloaded. Converts an IEnumerable or generic IEnumerable<T> to an IQueryable or generic IQueryable<T>.
Public method Static member Average Overloaded. Computes the average of a sequence of numeric values.
Public method Static member Cast<TResult> Converts the elements of an IQueryable to the specified type.
Public method Static member Concat<TSource> Concatenates two sequences.
Public method Static member Contains Overloaded. Determines whether an IQueryable<T> contains a specified element.
Public method Static member Count Overloaded. Returns the number of elements in a sequence.
Public method Static member DefaultIfEmpty Overloaded. Returns the elements in a sequence or a default valued singleton collection if the sequence is empty.
Public method Static member Distinct Overloaded. Returns distinct elements from a sequence.
Public method Static member ElementAt<TSource> Returns the element at a specified index in a sequence.
Public method Static member ElementAtOrDefault<TSource> Returns the element at a specified index in a sequence or a default value if the index is out of range.
Public method Static member Except Overloaded. Produces the set difference of two sequences.
Public method Static member First Overloaded. Returns the first element of a sequence.
Public method Static member FirstOrDefault Overloaded. Returns the first element of a sequence, or a default value if no element is found.
Public method Static member GroupBy Overloaded. Groups the elements of a sequence.
Public method Static member GroupJoin Overloaded. Correlates the elements of two sequences based on key equality and groups the results.
Public method Static member Intersect Overloaded. Produces the set intersection of two sequences.
Public method Static member Join Overloaded. Correlates the elements of two sequences based on matching keys.
Public method Static member Last Overloaded. Returns the last element in a sequence.
Public method Static member LastOrDefault Overloaded. Returns the last element of a sequence, or a default value if no element is found.
Public method Static member LongCount Overloaded. Returns an Int64 that represents the number of elements in sequence.
Public method Static member Max Overloaded. Returns the maximum value in a sequence.
Public method Static member Min Overloaded. Returns the minimum value in a sequence.
Public method Static member OfType<TResult> Filters the elements of an IQueryable based on a specified type.
Public method Static member OrderBy Overloaded. Sorts the elements of a sequence in ascending order.
Public method Static member OrderByDescending Overloaded. Sorts the elements of a sequence in descending order.
Public method Static member Reverse<TSource> Inverts the order of the elements in a sequence.
Public method Static member Select Overloaded. Projects each element of a sequence into a new form.
Public method Static member SelectMany Overloaded. Projects each element of a sequence to an IEnumerable<T> and combines the resulting sequences into one sequence of type IQueryable<T>.
Public method Static member SequenceEqual Overloaded. Determines whether two sequences are equal.
Public method Static member Single Overloaded. Returns a single, specific element of a sequence.
Public method Static member SingleOrDefault Overloaded. Returns a single, specific element of a sequence, or a default value if no such element is found.
Public method Static member Skip<TSource> Bypasses a specified number of elements in a sequence and then returns the remaining elements.
Public method Static member SkipWhile Overloaded. Bypasses elements in a sequence as long as a specified condition is true and then returns the remaining elements.
Public method Static member Sum Overloaded. Computes the sum of a sequence of numeric values.
Public method Static member Take<TSource> Returns a specified number of contiguous elements from the start of a sequence.
Public method Static member TakeWhile Overloaded. Returns elements from a sequence as long as a specified condition is true, and then skips the remaining elements.
Public method Static member ThenBy Overloaded. Performs a subsequent ordering of the elements in a sequence in ascending order.
Public method Static member ThenByDescending Overloaded. Performs a subsequent ordering of the elements in a sequence in descending order.
Public method Static member Union Overloaded. Produces the set union of two sequences.
Public method Static member Where Overloaded. Filters a sequence of values based on a predicate.
