有没有办法在 Windows Server 上使用 IIS 更改已保存文件的所有者。越容易越好。在文件已保存到光盘后，必须在保存或更改文件所有者期间完成此操作并不重要。 ASP.NET 中的一个示例非常受欢迎。

从理论上讲，它应该相当简单。您应该能够执行类似的操作来更改现有文件的所有权：

string domain = "domain";
string user = "username";

FileInfo info = new FileInfo(@"c:\test.txt");

FileSecurity security = info.GetAccessControl();

System.Security.Principal.NTAccount newOwner =
    new System.Security.Principal.NTAccount(domain, user);

security.AddAccessRule(
        new FileSystemAccessRule(newOwner, FileSystemRights.FullControl,
            AccessControlType.Allow));
security.SetAccessRuleProtection(true, false);
security.SetOwner(newOwner);

info.SetAccessControl(security);

但实际上，由于 Windows 施加的限制，这实际上不起作用。 Windows 不允许您将文件的所有者更改为当前用户或管理员组以外的任何人。

当它到达最后一行时，您将收到异常“安全标识符不允许成为该对象的所有者”。

谷歌搜索表明也许可以解决这个问题，但是当我过去尝试时，我未能让解决方法发挥作用。我很想知道是否有人成功地解决了这个问题。

In theory it should be fairly straight forward. You should be able to do something like this to change the ownership of an existing file:

string domain = "domain";
string user = "username";

FileInfo info = new FileInfo(@"c:\test.txt");

FileSecurity security = info.GetAccessControl();

System.Security.Principal.NTAccount newOwner =
    new System.Security.Principal.NTAccount(domain, user);

security.AddAccessRule(
        new FileSystemAccessRule(newOwner, FileSystemRights.FullControl,
            AccessControlType.Allow));
security.SetAccessRuleProtection(true, false);
security.SetOwner(newOwner);

info.SetAccessControl(security);

In practice however this doesn't actually work because of a limitation that Windows imposes. Windows won't allow you to the change the owner of the file to anything other than the current user or the administrators group.

When it hits the last line you will get the exception "The security identifier is not allowed to be the owner of this object".

Googling suggests that it may be possible to work round this problem, but I have failed to get the work arounds to work when I have tried in the past. I'd be very interested to hear if anyone had successfully achieved the work around.
