爲什麼ASP.NET MVC路徑顯示變量？

Question

在我的MVC應用程序，爲什麼

Return RedirectToAction("Edit", "Forms", New With {.member = "123"}) 

回報

http://localhost:13/Forms/Edit?member=123 

的

http://localhost:13/Forms/Edit/123 

insted的？

又爲何

<%=Html.ActionLink("MyLink", "Edit", "Forms", New With {.member = "123"}, Nothing)%> 

做同樣的事情？

Answer 1

標準路由設置爲使用id作爲第三個參數。將「member」更改爲「id」，您將獲得您期望的路線。

Return RedirectToAction("Edit", "Forms", New With { .id = "123"}) 

Answer 2

正如tvanfosson所說，「id」是默認路由引擎設置要查找的內容。還有其他的第三個參數，它將作爲查詢字符串進行計算。

爲什麼？

routes.MapRoute(
    "Default", 
    "{controller}/{action}/{id}", 
    new { controller = "Home", action = "Index", id = "" } 
); 

您可以通過添加額外的routes.MapRoute（）線改變這一點，就像這樣：

routes.MapRoute(
    "Default", 
    "{controller}/{action}/{id}", 
    new { controller = "Home", action = "Index", id = "" } 
); 

routes.MapRoute(
    "Default2", 
    "{controller}/{action}/{member}", 
    new { controller = "Home", action = "Index", member = "" } 
);
