Question

System.UnauthorizedAccessException: Access to the path 'C:\Inetpub\wwwroot\Spicee    Webservice\App_Data\Employee.xml' is denied.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32   rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy)
at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share)
at System.Xml.XmlTextWriter..ctor(String filename, Encoding encoding)
at ResturantService.InsertDatabaseXML(String servername, String dbusername, String dbpassword, String dbname, String port)

当我尝试编写xml文件时出现上述错误。当我从VS2008运行时，代码工作正常。

我知道这与iis文件夹的权限设置有关。但我不想做权限设置手册，因为我们的计划是通过网站部署包分发应用程序用户不会想到手动设置权限。

当我尝试使用以下代码为iisuser设置文件夹的权限时。

 Directory.CreateDirectory(sPathName);
        DirectoryInfo info = new DirectoryInfo(sPathName);
        DirectorySecurity security = info.GetAccessControl();

        security.AddAccessRule(new FileSystemAccessRule(@"TAG1\IUSR_TAG1", FileSystemRights.FullControl, InheritanceFlags.ContainerInherit, PropagationFlags.None, AccessControlType.Allow));
        security.AddAccessRule(new FileSystemAccessRule(@"TAG1\IUSR_TAG1", FileSystemRights.FullControl, InheritanceFlags.ObjectInherit, PropagationFlags.None, AccessControlType.Allow));

        info.SetAccessControl(security);

我收到此错误。

System.UnauthorizedAccessException: Attempted to perform an unauthorized operation.
at System.Security.AccessControl.Win32.SetSecurityInfo(ResourceType type, String name, SafeHandle handle, SecurityInfos securityInformation, SecurityIdentifier owner, SecurityIdentifier group, GenericAcl sacl, GenericAcl dacl)
at System.Security.AccessControl.NativeObjectSecurity.Persist(String name, SafeHandle handle, AccessControlSections includeSections, Object exceptionContext)

at System.IO.DirectoryInfo.SetAccessControl(DirectorySecurity directorySecurity)
at ResturantService.InsertDatabaseXML(String servername, String dbusername, String dbpassword, String dbname, String port)

请帮我解决这个问题。

提前致谢。

您需要更改用于部署站点的任何内容，以便为执行此代码的任何帐户授予写入权限，或者您需要将其放在其他位置，或者您需要设置另一个可以这样做，所以你不要向每个人和他的狗分发许可。

系统如何手动工作没有什么不同。如果您以低权限用户身份登录，则不能仅为自己分配更高的权限。您必须获得更高级别的授权才能执行此操作。这就像是UAC，或SUDO。
