Namespace:  System.Data.Objects
Assembly:  System.Data.Entity (in System.Data.Entity.dll)

member OrderBy : 
        keys:string * 
        parameters:ObjectParameter[] -> ObjectQuery<'T> 


Type: System.String

The key columns by which to order the results.

Zero or more parameters that are used in this method.

Return Value

Type: System.Data.Objects.ObjectQuery(T)
A new ObjectQuery(T) instance that is equivalent to the original instance with ORDER BY applied.


The keys or parameters parameter is a null reference (Nothing in Visual Basic).


The key is an empty string.

The ordering of results in a nested query cannot be guaranteed.

OrderBy should always be the final query builder method in the sequence.

This example is based on the Adventure Works Sales Model. The example creates a new ObjectQuery(T) object that contains the results of the existing query order by ProductID.
