MVC RouteUrl沒有履行排除屬性

如何使用Url.RouteUrl(object)當我排除進入查詢字符串某些屬性？

具體來說，在我的Model對象被傳遞給我的視圖，我有一個字符串數組（技術上IEnumerable <字符串>）我想排除。

我認爲與排除的綁定屬性應該這樣做，但它不起作用。我試圖把[Bind(Exclude = "Sizes")]上我的課，但我不斷收到的URL看起來像這樣：

的http：//本地主機/尺寸= System.String []將用於

所有匿名對象的屬性而AFAIK沒有辦法排除一些。 [Bind]屬性用於控制器動作參數，以指示應從模型綁定中排除或包含的模型綁定器屬性，但不用於構建url。您可能需要通過一個指定要一個屬性：

Url.RouteUrl(new { 
    Prop1 = Model.Prop1, 
    Prop2 = Model.Prop2, 
    action = "SomeAction", 
    controller = "SomeController" 
})

或只包括ID：

Url.RouteUrl(new { 
    id = Model.Id, 
    action = "SomeAction", 
    controller = "SomeController" 
})

，並有目標控制器動作來使用這個號碼，以獲取從模型一些持久性數據存儲。
