The Queryable type exposes the following members.

Methods

  NameDescription
Public methodStatic memberAggregateOverloaded. Applies an accumulator function over a sequence.
Public methodStatic memberAll<(Of <(TSource>)>)Determines whether all the elements of a sequence satisfy a condition.
Public methodStatic memberAnyOverloaded. Determines whether any element of an IQueryable<(Of <(T>)>) sequence exists or satisfies a condition.
Public methodStatic memberAsQueryableOverloaded. Converts an IEnumerable or generic IEnumerable<(Of <(T>)>) to an IQueryable or generic IQueryable<(Of <(T>)>).
Public methodStatic memberAverageOverloaded. Computes the average of a sequence of numeric values.
Public methodStatic memberCast<(Of <(TResult>)>)Converts the elements of an IQueryable to the specified type.
Public methodStatic memberConcat<(Of <(TSource>)>)Concatenates two sequences.
Public methodStatic memberContainsOverloaded. Determines whether an IQueryable<(Of <(T>)>) contains a specified element.
Public methodStatic memberCountOverloaded. Returns the number of elements in a sequence.
Public methodStatic memberDefaultIfEmptyOverloaded. Returns the elements in a sequence or a default valued singleton collection if the sequence is empty.
Public methodStatic memberDistinctOverloaded. Returns distinct elements from a sequence.
Public methodStatic memberElementAt<(Of <(TSource>)>)Returns the element at a specified index in a sequence.
Public methodStatic memberElementAtOrDefault<(Of <(TSource>)>)Returns the element at a specified index in a sequence or a default value if the index is out of range.
Public methodStatic memberExceptOverloaded. Produces the set difference of two sequences.
Public methodStatic memberFirstOverloaded. Returns the first element of a sequence.
Public methodStatic memberFirstOrDefaultOverloaded. Returns the first element of a sequence, or a default value if no element is found.
Public methodStatic memberGroupByOverloaded. Groups the elements of a sequence.
Public methodStatic memberGroupJoinOverloaded. Correlates the elements of two sequences based on key equality and groups the results.
Public methodStatic memberIntersectOverloaded. Produces the set intersection of two sequences.
Public methodStatic memberJoinOverloaded. Correlates the elements of two sequences based on matching keys.
Public methodStatic memberLastOverloaded. Returns the last element in a sequence.
Public methodStatic memberLastOrDefaultOverloaded. Returns the last element of a sequence, or a default value if no element is found.
Public methodStatic memberLongCountOverloaded. Returns an Int64 that represents the number of elements in sequence.
Public methodStatic memberMaxOverloaded. Returns the maximum value in a sequence.
Public methodStatic memberMinOverloaded. Returns the minimum value in a sequence.
Public methodStatic memberOfType<(Of <(TResult>)>)Filters the elements of an IQueryable based on a specified type.
Public methodStatic memberOrderByOverloaded. Sorts the elements of a sequence in ascending order.
Public methodStatic memberOrderByDescendingOverloaded. Sorts the elements of a sequence in descending order.
Public methodStatic memberReverse<(Of <(TSource>)>)Inverts the order of the elements in a sequence.
Public methodStatic memberSelectOverloaded. Projects each element of a sequence into a new form.
Public methodStatic memberSelectManyOverloaded. Projects each element of a sequence to an IEnumerable<(Of <(T>)>) and combines the resulting sequences into one sequence of type IQueryable<(Of <(T>)>).
Public methodStatic memberSequenceEqualOverloaded. Determines whether two sequences are equal.
Public methodStatic memberSingleOverloaded. Returns a single, specific element of a sequence.
Public methodStatic memberSingleOrDefaultOverloaded. Returns a single, specific element of a sequence, or a default value if no such element is found.
Public methodStatic memberSkip<(Of <(TSource>)>)Bypasses a specified number of elements in a sequence and then returns the remaining elements.
Public methodStatic memberSkipWhileOverloaded. Bypasses elements in a sequence as long as a specified condition is true and then returns the remaining elements.
Public methodStatic memberSumOverloaded. Computes the sum of a sequence of numeric values.
Public methodStatic memberTake<(Of <(TSource>)>)Returns a specified number of contiguous elements from the start of a sequence.
Public methodStatic memberTakeWhileOverloaded. Returns elements from a sequence as long as a specified condition is true, and then skips the remaining elements.
Public methodStatic memberThenByOverloaded. Performs a subsequent ordering of the elements in a sequence in ascending order.
Public methodStatic memberThenByDescendingOverloaded. Performs a subsequent ordering of the elements in a sequence in descending order.
Public methodStatic memberUnionOverloaded. Produces the set union of two sequences.
Public methodStatic memberWhereOverloaded. Filters a sequence of values based on a predicate.
