如何把网络共享目录映射为本地驱动器

要映射一个网络目录为本地驱动器，需要调用系统DLL的WNetAddConnection2函数来进行添加。

 

首先，系统函数的申明如下：

using System.Runtime.InteropServices;

 

    [DllImport("mpr.dll", EntryPoint="WNetAddConnection2")]

    public static extern uint WNetAddConnection2(

[In] NETRESOURCE lpNetResource,

string lpPassword,

string lpUsername,

uint dwFlags);

 

    [DllImport("Mpr.dll")]

    public static extern uint WNetCancelConnection2(

string lpName,

uint dwFlags,

bool fForce);

 

    [StructLayout(LayoutKind.Sequential)]

    public class NETRESOURCE

    {   

        public int dwScope;   

        public int dwType;

        public int dwDisplayType;   

        public int dwUsage;   

        public string LocalName;   

        public string RemoteName;   

        public string Comment;   

        public string Provider;

    }

    添加映射网络驱动器调用的代码如下：

    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 = "T:";       

    myNetResource.RemoteName = yourNetworkPath;       

    myNetResource.Provider = null;       

 

    uint nret = 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 nret = WNetCancelConnection2( yourNetDriveName, 1, true);

 

 

 

首先，要在工程中引用Windows.Management。

 

然后，就是用WMI进行查询，代码如下：

    public enum DRIVE_TYPE:int

    {

        REMOVABLE       = 2,

        LOCALDISK       = 3,

        NETDRIVE            = 4,

        CDROM           = 5,

    }

 

    public ArrayList GetAllNetDriveName()

    {

        //get drive collection

        string strQuery = string.Format( "SELECT * From Win32_LogicalDisk WHERE DriveType = {0}", (int)( DRIVE_TYPE.NETDRIVE) );

 

        ManagementObjectSearcher query = new ManagementObjectSearcher(strQuery);

        ManagementObjectCollection queryCollection = query.Get();

 

        ArrayList arrNetDriveName = new ArrayList();

        foreach ( ManagementObject mo in queryCollection)

            arrNetDriveName.Add( mo["Name"].ToString() );

        return arrNetDriveName;

    }

 

       网络驱动器的盘符已经获得，那么删除，就可以调用原来的方法，参见：
