C#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)
{
if (!disposed)
{
RevertToSelf();
disposed = true;
}
}
public void Dispose()
{
Dispose(true);
}
}
}

 案例：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
namespace ConsoleApplication5
{
class Program
{
static void Main(string[] args)
{
using (SharedTool tool = new SharedTool("administrator", "12345678", "192.168.1.101"))
{
string selectPath = @"\\192.168.1.101\c$";
var dicInfo = new DirectoryInfo(selectPath);//选择的目录信息
DirectoryInfo[] dic = dicInfo.GetDirectories("*.*", SearchOption.TopDirectoryOnly);
foreach (DirectoryInfo temp in dic)
{
Console.WriteLine(temp.FullName);
}
Console.WriteLine("---------------------------");
FileInfo[] textFiles = dicInfo.GetFiles("*.*", SearchOption.TopDirectoryOnly);//获取所有目录包含子目录下的文件
foreach (FileInfo temp in textFiles)
{
Console.WriteLine(temp.Name);
}
}
Console.ReadKey();
}
}
}
