客户端外网访问服务器共享文件夹访问用户控制

[fengziyoyo]

如题，在winform客户端访问可在外网访问的服务器共享文件夹，如果共享文件夹的访问权限都放开的话，匿名访问时可以的，现在想在次基础上实现通过用户名和密码访问，怎么去实现？
1、wmi
我查了些资料，说wmi可以做，试了一下总是报连接异常:rpc服务器不可用；而连接本地时则报:无法获取本地用户凭证;望各位解答！
2、映射网络硬盘
不知还有没有其他的方式呢？希望各位能给小弟关于这方面的比较全面的上一课，谢谢。

刚才网把wmi部分的包异常的代码贴出来了,异常代码如下:
ConnectionOptions options = new ConnectionOptions();
options.Username = "huang";//UserName; //could be in domain\user format
options.Password = "1234";//SecurelyStoredPassword;
ManagementScope scope = new ManagementScope("\\\\huang\\root\\cimv2",options);//"\\\\servername\\root\\cimv2",options);
try
{
scope.Connect();
ManagementObject disk = new ManagementObject(scope,new ManagementPath("Win32_logicaldisk='c:'"),null);
disk.Get();
}
catch (Exception ex)
{
Console.WriteLine("Failed to connect: " + ex.Message);
}

感谢Knight94(愚翁)的支持，您的blog我已看过，正在研究，谢谢！

刚才试了一下那段代码，没有实现，下面是我的代码：
string yourNetworkPath = ConfigurationSettings.AppSettings["yourNetworkPath"];
if(yourNetworkPath == "")
{
yourNetworkPath = this.textBox1.Text.Trim();
}
string pwd = ConfigurationSettings.AppSettings["pwd"];
string username = ConfigurationSettings.AppSettings["username"];
string yourNetDriveName = ConfigurationSettings.AppSettings["yourNetDriveName"];

NETRESOURCE myNetResource = new NETRESOURCE();

myNetResource.dwScope = 2; //2:RESOURCE_GLOBALNET

myNetResource.dwType = 1 ; //1:RESOURCETYPE_ANY

myNetResource.dwDisplayType = 3; //3:RESOURCEDISPLAYTYPE_GENERIC

myNetResource.dwUsage = 1; //1: RESOURCEUSAGE_CONNECTABLE

myNetResource.LocalName = yourNetDriveName;

myNetResource.RemoteName = yourNetworkPath;

myNetResource.Provider = null;

uint nretAdd = WNetAddConnection2( myNetResource, pwd, username, 0);

//注意：如果正确，返回值是0；否则错误。

//删除映射网络驱动器调用的代码如下：

//uint nretDel = WNetCancelConnection2( yourNetDriveName, 1, true);

string[] files1 = Directory.GetFiles(yourNetworkPath);

if(File.Exists(@"T:\vss\users.txt"))
{
FileInfo file = new FileInfo(@"T:\vss\users.txt");

}
nretAdd 的返回值是1219，并不时代表正确的0,可以解释一下么？

to
myNetResource.LocalName = yourNetDriveName;
myNetResource.RemoteName = yourNetworkPath;

这两个具体的值是什么

[fengziyoyo]

myNetResource.LocalName = yourNetDriveName;//映射到本地的盘符
myNetResource.RemoteName = yourNetworkPath; //需要映射的共享文件夹的地址

问题解决了，谢谢愚翁
