c# winform 程序怎么列出一台机器上面的共享目录？

Question

如题

Answer 1

先using System.Management;一下,然后
ObjectQuery objectQuery = new ObjectQuery("select * from Win32_Share");//share object ManagementObjectSearcher searcher =new ManagementObjectSearcher(objectQuery);
txtMsg.Text="";
PropertyDataCollection pdc;
foreach (ManagementObject share in searcher.Get())
{
pdc=share.Properties;
txtMsg.Text+="======================================"+"\r\n";
txtMsg.Text+=share.Path+"\r\n";
foreach(PropertyData pd in pdc)
{
txtMsg.Text+=pd.Name+"="+pd.Value+"\r\n";
}
}

终于知道怎么获取共享目录啦[StructLayout(LayoutKind.Sequential)] 
protected struct SHARE_INFO_1 
{ 
  [MarshalAs(UnmanagedType.LPWStr)] public string shi1_netname; 
  [MarshalAs(UnmanagedType.U4)] public uint shi1_type; 
  [MarshalAs(UnmanagedType.LPWStr)] public string shi1_re; 
} //98没有这个函数？
[DllImport("Netapi32.dll", EntryPoint="NetShareEnum")] 
protected static extern int NetShareEnum( 
[MarshalAs(UnmanagedType.LPWStr)] string servername, 
[MarshalAs(UnmanagedType.U4)] uint level, 
out IntPtr bufptr, 
[MarshalAs(UnmanagedType.U4)] int prefmaxlen, 
[MarshalAs(UnmanagedType.U4)] out uint entriesread, 
[MarshalAs(UnmanagedType.U4)] out uint totalentries, 
[MarshalAs(UnmanagedType.U4)] out uint resume_handle 
);
private string[] NetShareEnum(string server)
{

  IntPtr buffer;
  uint entriesread;
  uint totalentries;
  uint resume_handle;//-1应该是获取所有的share,msdn里面的例子是这么写的,返回0表示成功
if(NetShareEnum(server,1,out buffer,-1,out entriesread,out totalentries,out resume_handle)==0)
{
Int32 ptr = buffer.ToInt32(); 
ArrayList alShare=new ArrayList();
for (int i=0; i<entriesread; i++) 
{ 

SHARE_INFO_1 shareInfo = (SHARE_INFO_1)Marshal.PtrToStructure(new IntPtr(ptr), typeof(SHARE_INFO_1));  
    if(shareInfo.shi1_type==0)//Disk drive类型
   {
alShare.Add(shareInfo.shi1_netname);
   }
   ptr += Marshal.SizeOf(shareInfo);//有点类似C代码
}
string[] share=new string[alShare.Count];
for(int i=0;i<alShare.Count;i++)
{
share[i]=alShare[i].ToString();
}
return share;
}
else
return null;

}
