c#实现启用禁用本地网络的三种方式-dsd999的专栏-csdn博客

1、C#实现启用、禁用本地网络的三种方式-dsd999的专栏CSDN 博客C#实现启用、禁用本地网络的三种方式收藏1) 使用 Hnetcfg.dll会生成 3使用 Add Reference, 把 Hnetcfg.dll 导入到工程中， 个引用，主要使用 NETCONLib 。在工程中要 using NETCONLib; / 本段代码不可用 ?2010-11-18下面是实现的代码：NetSharingManagerClass netSharingMgr = newNetSharingManagerClass();INetSharingEveryConnectionCollection connec

2、tions = netSharingMgr.EnumEveryConnection;foreach (INetConnection connection in connections)INetConnectionProps connProps = netSharingMgr.get_NetConnectionProps(connection); if (connProps.MediaType = tagNETCON_MEDIATYPE.NCM_LAN)connection.Disconnect(); / 禁用网络 connection.Connect();/ 启用网络2) 使用 Shell32

3、.dllshell32.dll 是 Windows 壳 Shell 相关应用程序接口动态链接 库文件，用于打开网页和文件。使用 Add Reference, 把 Shell32.dll 导入到工程中。在工程中要 using Shell32;下面是实现的代码：const string discVerb = 停用 (&B); const string connVerb = 启用 (&A); Shell sh = new Shell32.Shell();Folder folder;Folder fd;folder = sh.NameSpace(3);foreach (FolderIt

4、em myItem in folder.Items() if (myItem.Name = 网络连接 )fd = (Folder)myItem.GetFolder;/禁用网络foreach (FolderItem fi in fd.Items()foreach (FolderItemVerb Fib in fi.Verbs()if (Fib.Name = discVerb)Fib.DoIt();break;Thread.Sleep(3000);foreach (FolderItemVerb Fib in fi.Verbs()/启用网络if (Fib.Name = connVerb)Fib.Do

5、It();break;3) 使用 setupapi.dllsetupapi.dll 是流行的安装程序支持相关文件setupapi.dll 不能象前面两个通过 Add Reference 导入到工 程中，只能使用 DllImport代码比较多，贴主要代码DllImport(setupapi.dll)public static extern IntPtrSetupDiGetClassDevsA(ref Guid ClassGuid, UInt32 Enumerator,IntPtr hwndParent, UInt32 Flags);DllImport(setupapi.dll)public st

6、atic extern IntPtr SetupDiGetClassDevs(UInt32 ClassGuid, String e, IntPtr hwndParent, UInt32 Flags);DllImport(setupapi.dll)static extern BooleanSetupDiEnumDeviceInfo(IntPtr DeviceInfoSet, UInt32 MemberIndex,ref SP_DEVINFO_DATA DeviceInfoData);uint NewNetStatus = 0;if (newStatus)NewNetStatus = DICS_E

7、NABLE;elseNewNetStatus = DICS_DISABLE;IntPtr NewDeviceInfoSet;SP_DEVINFO_DATA spData = new SP_DEVINFO_DATA();spData.cbSize = (uint)System.Runtime.InteropServices.Marshal.SizeOf(sp Data);UInt32 RequiredSize = 0;byte st1 = new byte1024;uint Data = 0;NewDeviceInfoSet = SetupDiGetClassDevs(0, PCI, IntPt

8、r.Zero, DIGCF_PRESENT | DIGCF_ALLCLASSES); bool bFound = false;for (uint i = 0; SetupDiEnumDeviceInfo(NewDeviceInfoSet, i, ref spData); i+)while(!SetupDiGetDeviceRegistryProperty(NewDeviceInfoSet, ref spData, SPDRP_HARDWAREID, ref Data, st1, 1024, ref RequiredSize)string str = System.Text.Encoding.A

9、SCII.GetString(st1); ; char a = 0 ;string strSPlit = str.Split(a,StringSplitOptions.RemoveEmptyEntries);string HardId = PCIVEN_10EC&DEV_8029&SUBSYS_0000 0000;for (uint j = 0; j < strSPlit.Length; j+)if (strSPlitj = HardId)bFound = true; break;if (bFound) break;SP_PROPCHANGE_PARAMS spPropC

10、hangeParam = new SP_PROPCHANGE_PARAMS(); spPropChangeParam.Scope = DICS_FLAG_GLOBAL; spPropChangeParam.StateChange = NewNetStatus; spPropChangeParam.ClassInstallHeader.cbSize = (UInt32)System.Runtime.InteropServices.Marshal.SizeOf( spPropChangeParam.ClassInstallHeader); spPropChangeParam.ClassInstallHeader.InstallFunction = DIF_PROPERTYCHANGE;SetupDiSetClassInstallParams(NewDeviceInfoSet, ref spData, ref spPropChangeParam.ClassInstallHeader, System.Runtime.InteropServices.Marshal.SizeOf(spPropC hangeParam);SetupDiCallClassInstaller(DIF_PROPERTYCHANGE,Ne
