将电子邮件附件保存到UNC路径

Question

我在为Outlook编写的VSTO加载项中有以下代码:

        savefolder = Regex.Replace(Guid.NewGuid().ToString(), @"[- ]", String.Empty);

        savepathfull = string.Format(@"{0}{1}", netloc, savefolder);
        DirectoryInfo di = new DirectoryInfo(@savepathfull);
        if (!(di.Exists))
            Directory.CreateDirectory(@savepathfull);



        removedFiles = new List<string>();

        for (int d = attachs.Count; d > 0; d--)
        {
            if (attachs[d].Size > smallAttachment)
            {
                removedFiles.Add(attachs[d].FileName);
                attachs[d].SaveAsFile(savepathfull);
            }
        }

一切正常,直到我尝试保存附件,此时我收到UnauthorizedAccessException.我知道我的测试用户拥有该文件夹的完全权限,但我仍然收到此错误.

想法？

谢谢.

调用时需要提供有效的文件名Attachment.SaveAsFile.您正在尝试保存到目录,而不是文件.有关参考代码,请参阅MSDN .

attachs[d].SaveAsFile(Path.Combine(savepathfull, attachs[d].DisplayName);
