OrderBy(DbExpression, Func<DbExpression,DbExpression>)

Creates a new DbSortExpression that sorts the given input set by the specified sort key, with ascending sort order and default collation.

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

static member OrderBy : System.Data.Entity.Core.Common.CommandTrees.DbExpression * 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 OrderBy (source As DbExpression, sortKey As Func(Of DbExpression, DbExpression)) As DbSortExpression

Parameters

source: DbExpression

An expression that specifies the input set.

sortKey: Func<DbExpression,DbExpression>

A method that specifies how to derive the 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 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.
