Question

我有一个带有IIS设置的Azure VM，它托管我的ASP.Net网站。

我希望能够使用普通的Windows类库（System.IO）从网络共享（Azure文件存储）读取和写入文档/文件。我不想使用Azure存储客户端库，也不想使用Azure Storage Rest API。

我已按照this article中的详细说明安装了共享并保留了我的凭据。

安装驱动器并保留我的凭据后，我指向我的网站以使用我的共享驱动器来处理所有与文档管理相关的功能。下载文件非常有效。但是，只要我尝试创建文件夹或将文档写入网络共享，我就会收到错误。

我收到的错误是：

找不到路径的一部分＆f; [RestOfThePathHere]＆＃39;。   堆栈跟踪：

public ActionResult Upload(DocumentUploadVM VM, long ClientId, long ContextInstanceId, long DocumentClassId, long TaskId)
    {
            var documentClass = docMan.Get_DocumentClass(DocumentClassId);

            var errors = new List<string>();

            if (VM.File == null || VM.File.ContentLength == 0)
                errors.Add("You haven't selected a file to upload");
            else if (!documentClass.MimeTypeAllowed(VM.File.ContentType, docMan))
                errors.Add("The file type is forbidden");

            if (errors.Count == 0 && ModelState.IsValid)

                MemoryStream ms = new MemoryStream();

                    },

            }
            else
            {
                TempData["errors"] = errors;
            }

            //TODO: In case of model errors, this call will suppress the errors.  Look to TempData / PRG pattern to maintain model state over redirect.
            return
              RedirectToAction("ListClientDocuments", new { ClientId = ClientId, TaskId = TaskId });
        }

IFileHandler.SaveFile实现

public override void SaveFile(MemoryStream MemoryStream, string Fullpath)
    {
        var directory = Fullpath.Substring(0, Fullpath.LastIndexOf('\\')).TrimEnd('\\');
        var fileName = Fullpath.Replace(directory, "").Trim('\\');
        MemoryStream.ToArray()
        .SaveToFile(directory, fileName);
    }

PS - 请原谅可怕的代码和公然无视C＃编码标准。我写这篇文章时，我是个菜鸟。但是，当用于解决本地文件存储时，此代码尚未给我任何问题。

Answer 1

我认为您可能需要尝试创建映射到存储帐户用户的本地用户，然后将此用户添加到IIS_IUSRS组。
