c# - 如何在 C# 中使用身份验证打开文件夹？

Question

如何在 C# 中使用身份验证打开文件夹？我已经使用了 LogonUser 但它不起作用...

IntPtr token = IntPtr.Zero;
bool success = LogonUser("username", "domainname", "password",
    2, 0, ref token);
if (success)
{
    using (WindowsImpersonationContext person = new WindowsIdentity(token).Impersonate())
    {
        File.Copy(sourceFileName,destFileName);

        person.Undo();
        CloseHandle(token);
    }
}

成功是真的，我在 token 中收到一个数字，它输入 if 并给出用户错误和密码。

Everything works fine until it reaches the File.Copy part ERROR: I still got this error "Additional information: Logon failure: unknown user name or bad password."

我更改了代码，它对我来说工作正常，我把它留在这里以备不时之需。

        public static void ConnectToShare(string uri, string username, string password, string idFile, HttpPostedFileBase file)

        }



    }

然后从您的代码中调用它:

 ConnectToShare("dom", @"user", @"psw", file);
  DisconnectFromShare("dom", false);
