ASP.NET:获取正确的URL到上载的图像

问题描述

我上传这样的图片:

private const string ProfilePicturesUploadDir = "~/_useruploads/ProfilePictures/";

var fileName = System.Guid.NewGuid()+Path.GetExtension(file.FileName);
file.SaveAs(Path.Combine(HttpContext.Current.Server.MapPath(ProfilePicturesUploadDir), fileName));

我想在我的视图代码中检索正确的图像.我正在尝试:

I want to retrieve the correct image in my view code. I am trying this:

 public static string GetProfilePictureUrl(string profilePicture)
        {
            return HttpContext.Current.Server.MapPath(ProfilePicturesUploadDir + profilePicture);
        }

然后

 <img src="@FileService.GetProfilePictureUrl(Model.ProfilePicture)" width="250" height="250" />

但是它给了我404:找不到.

But it gives me a 404: Not found.

我该怎么办?我可以做得更好吗?

What should I do?Can I do this better?

推荐答案

使用:

@Url.Content(ProfilePicturesUploadDir)

获取文件夹的URL.
