Question

我不知道我在这里做什么，但是任何和所有参数都以null的形式传递给我的控制器，即使它们在呈现的HTML中已经明确定义。

查看

    @Html.ActionLink("Export to Spreadsheet", "Export", "ZipCodeTerritory"
    , new {
       @searchZip = Model.searchZip,
       @searchActiveOnly = Model.searchActiveOnly,
       @searchTerritory = Model.searchTerritory,
       @searchState = Model.searchState
    })

控制器

    public ActionResult Export(string searchZip, bool? searchActiveOnly, string searchTerritory, string searchState)
    {

呈现HTML

<a href="/ZipCodeTerritory/Export?Length=16" searchactiveonly="True" searchstate="CA" searchterritory="" searchzip="">Export to Spreadsheet</a>

Answer 1

你正在为Html.ActionLink使用错误的重载。它认为你的路线值实际上是html属性。此外，您需要删除每个变量名称中的“@”。尝试更改此内容：

@Html.ActionLink("Export to Spreadsheet", "Export", "ZipCodeTerritory"
, new {
   @searchZip = Model.searchZip,
   @searchActiveOnly = Model.searchActiveOnly,
   @searchTerritory = Model.searchTerritory,
   @searchState = Model.searchState
})

对此：

@Html.ActionLink("Export to Spreadsheet", "Export", "ZipCodeTerritory"
, new {
   searchZip = Model.searchZip,
   searchActiveOnly = Model.searchActiveOnly,
   searchTerritory = Model.searchTerritory,
   searchState = Model.searchState
}, null)

Answer 2

正在使用错误的重载，请尝试这样做：

@Html.ActionLink("Export to Spreadsheet", "Export", "ZipCodeTerritory"
    , 
     new {
       searchZip = Model.searchZip,
       searchActiveOnly = Model.searchActiveOnly,
       searchTerritory = Model.searchTerritory,
       searchState = Model.searchState
    }
    , null)

路由参数通过null
