本文實例總結了C#實現啟用與禁用本地網絡的方式。分享給大家供大家參考,具體如下:
1) 使用Hnetcfg.dll
使用Add Reference,把Hnetcfg.dll導入到工程中,會生成3個引用,主要使用NETCONLib。
在工程中要using NETCONLib;
下面是實現的代碼:
NetSharingManagerClass netSharingMgr = new NetSharingManagerClass();INetSharingEveryConnectionCollection connections = netSharingMgr.EnumEveryConnection;foreach (INetConnection connection in connections){INetConnectionProps connProps = netSharingMgr.get_NetConnectionProps(connection);if (connProps.MediaType == tagNETCON_MEDIATYPE.NCM_LAN){connection.Disconnect(); //禁用網絡connection.Connect(); //啟用網絡}}2) 使用Shell32.dll
shell32.dll是Windows殼Shell相關應用程序接口動態鏈接庫文件,用于打開網頁和文件。
使用Add Reference,把Shell32.dll導入到工程中。
在工程中要using Shell32;
下面是實現的代碼:
const string discVerb = "停用(&B)";const string connVerb = "啟用(&A)";Shell sh = new Shell32.Shell();Folder folder;Folder fd;folder = sh.NameSpace(3);foreach (FolderItem myItem in folder.Items()){if (myItem.Name == "網絡連接"){fd = (Folder)myItem.GetFolder;//禁用網絡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()){//啟用網絡if (Fib.Name == connVerb){Fib.DoIt();break;}}}}}3) 使用setupapi.dll
setupapi.dll是流行的安裝程序支持相關文件
setupapi.dll不能象前面兩個通過Add Reference導入到工程中,只能使用DllImport
代碼比較多,貼主要代碼
[DllImport("setupapi.dll")]public static extern IntPtrSetupDiGetClassDevsA(ref Guid ClassGuid, UInt32 Enumerator,IntPtr hwndParent, UInt32 Flags);[DllImport("setupapi.dll")]public static extern IntPtrSetupDiGetClassDevs(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_ENABLE;else NewNetStatus = DICS_DISABLE;IntPtr NewDeviceInfoSet;SP_DEVINFO_DATA spData = new SP_DEVINFO_DATA();spData.cbSize = (uint)System.Runtime.InteropServices.Marshal.SizeOf(spData);UInt32 RequiredSize = 0;byte[] st1 = new byte[1024];uint Data = 0;NewDeviceInfoSet = SetupDiGetClassDevs(0, "PCI", IntPtr.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.ASCII.GetString(st1); ;char[] a ={ '/0' };string[] strSPlit = str.Split(a, StringSplitOptions.RemoveEmptyEntries);string HardId = @"PCI/VEN_10EC&DEV_8029&SUBSYS_00000000";for (uint j = 0; j < strSPlit.Length; j++){if (strSPlit[j] == HardId){bFound = true;break;}} if (bFound) break;}SP_PROPCHANGE_PARAMS spPropChangeParam = 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(spPropChangeParam));SetupDiCallClassInstaller(DIF_PROPERTYCHANGE, NewDeviceInfoSet, ref spData);SetupDiDestroyDeviceInfoList(NewDeviceInfoSet);更多關于C#相關內容感興趣的讀者可查看本站專題:《C#窗體操作技巧匯總》、《C#常見控件用法教程》、《WinForm控件用法總結》、《C#程序設計之線程使用技巧總結》、《C#操作Excel技巧總結》、《C#中XML文件操作技巧匯總》、《C#數據結構與算法教程》、《C#數組操作技巧總結》及《C#面向對象程序設計入門教程》
