如何在F＃MVC5 Web应用程序中使用Razor传递数据。

例如，在下面的视图中， PostEmail 表单发布时，如何传递 newEmail 输入的值以及中的某些字段ViewData的

对于 DeleteEmail 表单，如何从电子邮件中选择所选的选项值？

我的观点：（Settings.cshtml）

<div style="width: 100%;">
    <h2 id="title" style="margin: 0 auto;">@ViewBag.PageTitle</h2> <br> <br>
    <div style="width: 60%; margin: 0 auto;">
        <div style="float: left; clear: none; width: 45%;">
            <span>EMAILS</span> <br>

            @using (Html.BeginForm("DeleteEmail", "QualityScore", FormMethod.Post))
            {
                <select id="emails" size="10" style="width: 100%; max-width: 100%">
                    @foreach (string email in ViewBag.EmailList)
                    {
                        <option value="@email">@email</option>
                    }
                </select>
                <input type="submit" id=" email_delete" value="Delete" />
            }

            @using (Html.BeginForm("PostEmail", "QualityScore", FormMethod.Post))
            {
                <input id="newEmail" />
                <input type="submit" id="email_create" value="Create" />
            }

        </div>
    </div>
</div>

我的控制器：（QualityScoreController.fs）

type QualityScoreController(queries : DataQueries) =
    inherit Controller()
    new () = new QualityScoreController(DataQueries())

    member this.Settings(token) = 
        let db = DataConnection.GetDataContext()

        let user = queries.FindUserByToken(token, db)

        this.ViewData.Add("PageTitle", "Your QualityScore Report Settings")
        this.ViewData.Add("EmailList", queries.FindUsersReportEmails(user.Id, db))
        this.ViewData.Add("KeywordList", queries.FindUsersReportBrands(user.Id, db))
        this.ViewData.Add("UserID", user.Id)

        this.View()

    member this.PostEmail() =
        ... //need to use information sent from the form

    member this.DeleteEmail() =
        ... //need to use information sent from the form

ASP.NET MVC会自动将表单值绑定到您的操作的同名参数：

auto ptr = do_something(); auto output = static_cast<another*>(ptr.get());

将数据从Razor Form Post传递给F＃控制器
