دوستان عزیز من این مطلب رو پیدا کردم
به این صورت که ابتدا در یک کلاس عمومی توابع زیر رو می نویسیم
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;
using BOOL = System.Boolean;
using DWORD = System.UInt32;
using LPWSTR = System.String;
using NET_API_STATUS = System.UInt32;
namespace GE.GeClasses
{
class ConectionClass
{
public class UNCAccess
{
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode)]
internal struct USE_INFO_2
{
internal LPWSTR ui2_local;
internal LPWSTR ui2_remote;
internal LPWSTR ui2_password;
internal DWORD ui2_status;
internal DWORD ui2_asg_type;
internal DWORD ui2_refcount;
internal DWORD ui2_usecount;

internal LPWSTR ui2_domainname;
}
[DllImport("NetApi32.dll", SetLastError = true, CharSet = CharSet.Unicode)]
internal static extern NET_API_STATUS NetUseAdd(
LPWSTR UncServerName,
DWORD Level,
ref USE_INFO_2 Buf,
out DWORD ParmError);
[DllImport("NetApi32.dll", SetLastError = true, CharSet = CharSet.Unicode)]
internal static extern NET_API_STATUS NetUseDel(
LPWSTR UncServerName,
LPWSTR UseName,
DWORD ForceCond);
private string sUNCPath;
private string sUser;
private string sPassword;
private string sDomain;
private int iLastError;
public UNCAccess()
{
}
public UNCAccess(string UNCPath, string User, string Domain, string Password)
{
login(UNCPath, User, Domain, Password);
}
public int LastError
{
get { return iLastError; }
}

public bool login(string UNCPath, string User, string Domain, string Password)
{
sUNCPath = UNCPath;
sUser = User;
sPassword = Password;
sDomain = Domain;
return NetUseWithCredentials();
}
private bool NetUseWithCredentials()
{
uint returncode;
try
{
USE_INFO_2 useinfo = new USE_INFO_2();
useinfo.ui2_remote = sUNCPath;
useinfo.ui2_username = sUser;
useinfo.ui2_domainname = sDomain;
useinfo.ui2_password = sPassword;
useinfo.ui2_asg_type = 0;
useinfo.ui2_usecount = 1;
uint paramErrorIndex;
returncode = NetUseAdd(null, 2, ref useinfo, out paramErrorIndex);
iLastError = (int)returncode;
return returncode == 0;
}
catch
{
iLastError = Marshal.GetLastWin32Error();
return false;
}
}
/// <summary>
/// Closes the UNC share
/// </summary>
/// <returns>True if closing was successful</returns>
public bool NetUseDelete()
{
uint returncode;
try
{
returncode = NetUseDel(null, sUNCPath, 2);
iLastError = (int)returncode;
return (returncode == 0);
}
catch
{
iLastError = Marshal.GetLastWin32Error();
return false;
}
}
}
}
}
سپس با دستور زیر خوانی میکنیم ولی نیدونم چه مشکلی داره که همیشه خطای 87 رو برمیگردونه اگه کسی راهنمایی کنه منون میشم
ConectionClass.UNCAccess unc = new ConectionClass.UNCAccess(@Distention, "username", "domain", "password");
