我有一个带有 IIS 设置的 Azure VM，它托管我的 ASP.Net 网站。
我希望能够通过使用普通的 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 存储客户端库或 Azure Storage Rest API。
如本文所述，我已安装共享并保留了我的凭据。
安装驱动器并保存我的凭据后，我将我的网站指向我的共享驱动器，以实现所有与文档管理相关的功能。下载文件完美无缺。但是，当我尝试创建文件夹或将文档写入网络共享时，我会收到错误消息。
我收到的错误是：
找不到路径“F:[RestOfThePathHere]”的一部分。堆栈跟踪：

更新 - 我当前的代码
MVC 控制器方法
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)
{
var path = settings.GetSettingValueAsString("Document Management: Client Documents Root Path").TrimEnd('\\') + "\\Uploads\\";
var pvtFileName = new Random().Next().ToString() + "." + VM.File.FileName.Split('.').Last();
var targetURI = Path.Combine(path, pvtFileName);
MemoryStream ms = new MemoryStream();
VM.File.InputStream.CopyTo(ms);
IFileHandler fh = FileHandlingFactory.Create();
fh.SaveFile(ms, targetURI);
docMan.Add_Document(
new FileItem
{
FilePathOnServer = path,
PublicFileName = VM.File.FileName,
PrivateFileName = pvtFileName,
MimeType = VM.File.ContentType
},
docMan.Get_ContextInstance(ContextInstanceId),
new List<DocumentClass> { documentClass });
}
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 - 请原谅糟糕的代码和公然无视 C# 编码标准。我写这篇文章的时候是个菜鸟。但是，当用于处理本地文件存储时，此代码还没有给我带来任何问题。
