阅读C#中的共享权限

Question

是否可以读取分配给共享文件夹的共享权限？我能够在本地安全设置programmaticaly(在右键单击>属性>安全性下找到的)读取没问题.但是,我想知道如何在右键单击>共享和安全...>权限下读取权限

这是我想要阅读的权限的图像:

这可能吗？如果有帮助,我正在运行XP Pro机器.

编辑:

按我的回答,我能够通过全部股份进行迭代,并获得访问您(即运行程序的人)对这一份额,但还没有找到一种方法来读取权限,其他人都在该共享.这是使用Win32_Share类完成的,但它没有获取其他用户的共享权限的选项.如果有人有任何有用的提示,将是一个巨大的帮助.

通过扩展Petey B采用的方法,我能够实现这一点.另外,请确保运行此代码的进程模拟服务器上的特权用户.

    using System;
    using System.Management;

    ...

    private static void ShareSecurity(string ServerName)
    {
        ConnectionOptions myConnectionOptions = new  ConnectionOptions();

        myConnectionOptions.Impersonation = ImpersonationLevel.Impersonate;            
        myConnectionOptions.Authentication = AuthenticationLevel.Packet;

        ManagementScope myManagementScope = 
            new ManagementScope(@"\\" + ServerName + @"\root\cimv2", myConnectionOptions);

        myManagementScope.Connect();

        if (!myManagementScope.IsConnected)
            Console.WriteLine("could not connect");
        else
        {
            ManagementObjectSearcher myObjectSearcher = 
                new ManagementObjectSearcher(myManagementScope.Path.ToString(), "SELECT * FROM Win32_LogicalShareSecuritySetting");

            foreach(ManagementObject share in myObjectSearcher.Get())
            {
                Console.WriteLine(share["Name"] as string);
                InvokeMethodOptions options = new InvokeMethodOptions();
                ManagementBaseObject outParamsMthd = share.InvokeMethod("GetSecurityDescriptor", null, options);
                ManagementBaseObject descriptor = outParamsMthd["Descriptor"] as ManagementBaseObject;
                ManagementBaseObject[] dacl =  descriptor["DACL"] as ManagementBaseObject[];                  

                foreach (ManagementBaseObject ace in dacl)
                {
                    try
                    {
                        ManagementBaseObject trustee = ace["Trustee"] as ManagementBaseObject;
                        Console.WriteLine(
                            trustee["Domain"] as string + @"\" + trustee["Name"] as string + ": " +
                            ace["AccessMask"] as string + " " + ace["AceType"] as string
                        );                            
                    }
                    catch (Exception error)
                    {
                        Console.WriteLine("Error: "+ error.ToString());
                    }
                }
            }               
        }
    }
