Net(C)创建网络映射磁盘

1、.NET(C#在网络上创建映射磁盘2、 在WEB 服务器上新建用户：administrator密码为： ，用户组选择默认的administrator 组即可。3、 在 WEB 工程中新建公共类WNetHelperpublicclassWNetHelperDllImport( mpr.dll, EntryPoint =WNetAddConnection2 privatestaticexternuintWNetAddConnection2( NetResource lpNetResource,stringlpPassword,stringlpUsername,uintdwFlags 。DllImp
