IOrderedQueryable<T> IOrderedQueryable<T> IOrderedQueryable<T> IOrderedQueryable<T> Interface

定義

代表排序作業的結果。Represents the result of a sorting operation.

generic <typename T>
public interface class IOrderedQueryable : System::Collections::Generic::IEnumerable<T>, System::Linq::IOrderedQueryable, System::Linq::IQueryable<T>
public interface IOrderedQueryable<out T> : System.Collections.Generic.IEnumerable<out T>, System.Linq.IOrderedQueryable, System.Linq.IQueryable<out T>
type IOrderedQueryable<'T> = interface
    interface IQueryable<'T>
    interface IOrderedQueryable
    interface seq<'T>
    interface IQueryable
    interface IEnumerable
Public Interface IOrderedQueryable(Of Out T)
Implements IEnumerable(Of Out T), IOrderedQueryable, IQueryable(Of Out T)

類型參數

T

資料來源的內容類型。The type of the content of the data source.

備註

IOrderedQueryable<T>介面是供查詢提供者執行。The IOrderedQueryable<T> interface is intended for implementation by query providers.

這個介面OrderBy代表呼叫ThenByOrderByDescending方法之排序查詢的結果。ThenByDescendingThis interface represents the result of a sorting query that calls the method(s) OrderBy, OrderByDescending, ThenBy or ThenByDescending. CreateQuery<TElement>(Expression)呼叫並傳遞表示排序查詢的運算式樹狀架構時, 產生IQueryable<T>的物件必須是實作為類型IOrderedQueryable<T>When CreateQuery<TElement>(Expression) is called and passed an expression tree that represents a sorting query, the resulting IQueryable<T> object must be of a type that implements IOrderedQueryable<T>.
