如何将上传的文件存储到 MVC 应用程序中的应用程序文件夹以外的位置

Question

我可以使用此代码成功上传文件：

 [HttpPost]
    public ActionResult Save(IEnumerable<HttpPostedFileBase> attachments)
    {
        // The Name of the Upload component is "attachments" 
        foreach (var file in attachments)
        {
            // Some browsers send file names with full path. This needs to be stripped.
            var fileName = Path.GetFileName(file.FileName);
            var physicalPath = Path.Combine(Server.MapPath("~/App_Data"), fileName);
            file.SaveAs(physicalPath);
        }
        // Return an empty string to signify success
        return Content("");
    }

但这会将文件放在正在运行的应用程序 App_Data 文件夹中。我想将文件放在我的局域网上的共享中。我已经尝试过下面的代码，但它总是将 myPath 附加到应用程序的路径中：

 [HttpPost]
public ActionResult Save(IEnumerable<HttpPostedFileBase> attachments)
    {
        // The Name of the Upload component is "attachments" 
        foreach (var file in attachments)
        {

// Some browsers send file names with full path. This needs to be stripped.
            var fileName = Path.GetFileName(file.FileName);
            //add possible new folder name to path
            var myPath = "//my-server-myshare/myfolder/";
            //combine with file name 
            var physicalPath = Path.Combine(Server.MapPath(myPath), fileName);

            file.SaveAs(physicalPath);
        }
        // Return an empty string to signify success
        return Content("");
    }

如何强制将其保存在我作为 myPath 的 URL 中？

Answer 1

网络共享需要是完整的 UNC 路径，因此请翻转斜线：

var myPath = @"\\my-server-myshare\myfolder\";

你也可以直接创建文件：

file.Create(@"\\my-server-myshare\myfolder\");
