MVC中上传文件

与asp.net中几乎一样，使用表单提交的方式上传文件（如果是使用了第三方插件的话，那么就另当别论）

@{
    ViewBag.Title = "Index";
    Layout = null;
}

<!DOCTYPE html>

<html>
<head>
    <title>@ViewBag.Title</title>    
</head>
<body>
    <form id="form1" method="post"  enctype="multipart/form-data" action="@Url.Action("SaveFiles")">
        <input type="file" name="file" value="" />
        <br />
        <input type="submit" value="提交" /> 
    </form>
</body>
</html>
View中的代码

 

var path = '@Url.Action("Upload", "ControllerName")' + "?para=" + escape($('#sltor').combobox('getValue')) + "&para1=" + $('#sltor').combobox('getValue') + "&para2=" + column + "&para3=" + pointCount;
                var fordata = new FormData();
                fordata.append('file', $('#InputUploadFile')[0].files[0]);
                $.ajax({
                    url: path,
                    type: 'post',
                    processData: false,
                    contentType: false,
                    data: fordata,
                    success: function (res) {
                        if (res.code == 200) {
                            GetData();
                            ShowMsg('上传成功！');
                        }
                        if (res.code == 400) {
                            ShowMsg(res.msg);
                        }
                    }, error: function (e) {
                        ShowMsg("认证已过期，请重新登录。");
                    },
                    headers: Obj.headers
                })
js中上传

 

在vue中可以直接使用 el-upload 组件。 

 

using System.IO;
using System.Web;
using System.Web.Mvc;

namespace PartyInvites.Controllers
{
    public class UploadController : Controller
    {
        //
        // GET: /Upload/

        public ActionResult Index()
        {
            return View();
        }

        [HttpPost]
        public ActionResult SaveFiles()
        {
            HttpPostedFileBase file = Request.Files["file"];
            if (file == null)
            {
                return Content("没有文件！", "text/plain");
            }
            var fileName = Path.Combine(Request.MapPath("~/UploadFiles"), Path.GetFileName(file.FileName));            
            try
            {
                file.SaveAs(fileName);
                return Content("上传成功！", "text/plain");      
            }
            catch 
            {
                return Content("上传异常！","text/plain");               
            }            
        }
    }
}
controller中代码
