c# - 通过提交按钮传递值？

Question

我试图通过表单的提交按钮传递值。

这些是我需要的值:

[HttpPost]
        public ActionResult Upload() //string token, string filename, string moddate, object file
        {
            Dictionary<string, string> parameters = new Dictionary<string, string>();
                parameters.Add("Token", token);
                parameters.Add("FileName", filename);
                parameters.Add("ModDate", DateTime.Today.ToString());
                parameters.Add("File", file);

            String compleat = "Complete";  
            return View(compleat);              
        }

这是我尝试获取值的地方:

<form action="/Home/Upload" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
@string token = @Model.Token;
@string fileName = file.tostring();
@File actualfile = file;
<br>
<input type="submit" name="submit" value="Submit" />

我想做这样的事情，我的 JavaScript 可能是错误的，因为我是新手。

单击提交后，如何从家庭 Controller 访问变量？

在 MVC 中，您想要使用 View 模型。还有 html.beginform 帮助器可以使用，这样你的代码就不会看起来那么困惑。

UploadViewModel.cs

public class UploadViewModel
{
    public string Token { get; set; }
    public string FileName { get; set; }
    public string ModDate { get; set; }
    public object File { get; set; }
}

HomeController.cs

    public ActionResult Upload()
    {
        TempData["Status"] = "";
        return View(new UploadViewModel());
    }

    [HttpPost]
    public ActionResult Upload(UploadViewModel upload) //string token, string filename, string moddate, object file
    {
        //*** Do something with the upload viewmodel

        // It's probably a good idea to store the message into tempdata
        TempData["Status"] = "Complete";
        return View();
    }

上传.cshtml

@model UploadViewModel

@Html.Label(TempData["Status"].ToString())
@using (Html.BeginForm())
{
    @Html.LabelFor(model => model.Token)
    @Html.EditorFor(model => model.Token)
    @Html.LabelFor(model => model.ModDate)
    @Html.EditorFor(model => model.ModDate)
    @Html.LabelFor(model => model.FileName)
    @Html.EditorFor(model => model.FileName)
    <input type="submit" name="submit" value="Submit" />
}

这是非常基础的东西，你应该阅读一些教程。像这样:http://www.asp.net/mvc/tutorials
