ThenByDescending(DbSortExpression, Func<DbExpression,DbExpression>)

Creates a new DbSortExpression that with a sort order that includes the sort order of the given order input set together with the specified sort key in descending sort order and with default collation.

public static System.Data.Entity.Core.Common.CommandTrees.DbSortExpression ThenByDescending (this System.Data.Entity.Core.Common.CommandTrees.DbSortExpression source, Func<System.Data.Entity.Core.Common.CommandTrees.DbExpression,System.Data.Entity.Core.Common.CommandTrees.DbExpression> sortKey);

static member ThenByDescending : System.Data.Entity.Core.Common.CommandTrees.DbSortExpression * Func<System.Data.Entity.Core.Common.CommandTrees.DbExpression, System.Data.Entity.Core.Common.CommandTrees.DbExpression> -> System.Data.Entity.Core.Common.CommandTrees.DbSortExpression

<Extension()>
Public Function ThenByDescending (source As DbSortExpression, sortKey As Func(Of DbExpression, DbExpression)) As DbSortExpression

Parameters

source: DbSortExpression

A DbSortExpression that specifies the ordered input set.

sortKey: Func<DbExpression,DbExpression>

A method that specifies how to derive the additional sort key expression given a member of the input set. This method must produce an expression with an order-comparable result type that provides the sort key definition.

Returns

DbSortExpression

A new DbSortExpression that represents the new overall order-by operation.

Exceptions

ArgumentNullException

The expression produced by sortKey is null.

ArgumentException

The expression produced by sortKey does not have an order-comparable result type.
