Asp.net MVC:上传多个图像文件? [英] Asp.net MVC: upload multiple image files?
问题描述
有如何在asp.net mvc的上传多个图像文件的一个很好的例子?我知道我们可以用HttpPostedFileBase上传一个文件。有没有通过点击一个按钮来上传多个文件的方法吗?
is there a good example of how to upload multiple image files in asp.net mvc? I know we can use HttpPostedFileBase to upload one file. Is there a way to upload multiple files by clicking one button?
我用的文件上传在ajaxtoolbox在网络表单前,喜欢它是如何工作的。是否有MVC类似的方式?或者,有没有一种现有的控制可以做到这一点呢?自由控制较好,但它是确定即使它的成本约$。
I used file upload in ajaxtoolbox in webform before and like how it works. Is there a similar way in MVC? or, is there a existing control that can do this well? free control is better, but it is ok even it costs some $.

推荐答案
使用此 jQuery插件
仅仅包含插件的js文件,创建标记:
just include plugin js files, create tag:
<input type='file' multiple id='fileUpload' name="files[]" data-url="@Url.Action("Upload","Home")" />
(除IE9是不允许在选择对话框中选择多个文件)
(Except IE9 it is not allowing select multiple files in select dialog)
添加一些JavaScript代码:
Add some JavaScript:
$(function () {
$('#fileUpload').fileupload({
dataType: 'json',
done: function (e, data) {
$.each(data.result.files, function (index, file) {
$('<p/>').text(file.name).appendTo(document.body);
});
}
});
});
在控制器动作只是检查Request.Files,做任何你想要的。
这里是一个很好的文档
In controller action just check Request.Files and do whatever you want. Here is a good documentation
[HttpPost]
public JsonResult Upload()
{
foreach (var file in Request.Files)
{
if(file.ContentLength > 0)
{
file.SaveAs(Server.MapPath("~/Upload/" + file.FileName));
}
}
return Json(new { result = true });
}
