C#如何访问共享文件夹或者磁盘如何访问共享文件夹或者磁盘
本文实例为大家分享了C#访问共享文件夹或者磁盘的具体代码，供大家参考，具体内容如下
SharedTool：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;
namespace ConsoleApplication5
{
public class SharedTool : IDisposable
{
// obtains user token
[DllImport("advapi32.dll", SetLastError = true)] static extern bool LogonUser(string pszUsername, string pszDomain, string
pszPassword,
int dwLogonType, int dwLogonProvider, ref IntPtr phToken);
// closes open handes returned by LogonUser
[DllImport("kernel32.dll", CharSet = CharSet.Auto)] extern static bool CloseHandle(IntPtr handle);
[DllImport("Advapi32.DLL")] static extern bool ImpersonateLoggedOnUser(IntPtr hToken);
[DllImport("Advapi32.DLL")] static extern bool RevertToSelf();
const int LOGON32_PROVIDER_DEFAULT = 0;
const int LOGON32_LOGON_NEWCREDENTIALS = 9;//域控中的需要用:Interactive = 2
private bool disposed;
public SharedTool(string username, string password, string ip)
{
// initialize tokens
IntPtr pExistingTokenHandle = new IntPtr(0);
IntPtr pDuplicateTokenHandle = new IntPtr(0);
try
{
// get handle to token
bool bImpersonated = LogonUser(username, ip, password,
LOGON32_LOGON_NEWCREDENTIALS, LOGON32_PROVIDER_DEFAULT, ref pExistingTokenHandle);
if (bImpersonated)
{
if (!ImpersonateLoggedOnUser(pExistingTokenHandle))
{
int nErrorCode = Marshal.GetLastWin32Error();
throw new Exception("ImpersonateLoggedOnUser error;Code=" + nErrorCode);
}
}
else
{
int nErrorCode = Marshal.GetLastWin32Error();
throw new Exception("LogonUser error;Code=" + nErrorCode);
}
}
finally
{
// close handle(s)
if (pExistingTokenHandle != IntPtr.Zero)
CloseHandle(pExistingTokenHandle);
if (pDuplicateTokenHandle != IntPtr.Zero)
CloseHandle(pDuplicateTokenHandle);
}
}
protected virtual void Dispose(bool disposing)
