在.NET的項(xiàng)目中,有時(shí)候需要獲取計(jì)算機(jī)的硬件的相關(guān)信息,在C#語言中需要利用ManagementClass這個(gè)類來進(jìn)行相關(guān)操作。

現(xiàn)在看一下MSDN對(duì)ManagementClass類的解釋,對(duì)表示一個(gè)通用信息模型 (CIM) 管理類。 管理類是 WMI 類,如 Win32_LogicalDisk, ,該類型可表示一個(gè)磁盤驅(qū)動(dòng)器,并 Win32_Process, ,它表示的進(jìn)程 Notepad.exe 等。 此類的成員可以訪問 WMI 數(shù)據(jù),使用一個(gè)特定的 WMI 類路徑。
一. 接下來我們來看一下ManagementClass類中一些較為常用的方法的源碼:
1.GetInstances():此方法存在四個(gè)重載
下面提供一下GetInstances(EnumerationOptions options)重載版本的代碼:
public ManagementObjectCollection GetInstances(EnumerationOptions options) { if ((null == Path) || (null == Path.Path) || (0 == Path.Path.Length)) throw new InvalidOperationException(); Initialize ( false ); IEnumWbemClassObject enumWbem = null; EnumerationOptions o = (null == options) ? new EnumerationOptions() : (EnumerationOptions)options.Clone(); o.EnsureLocatable = false; o.PrototypeOnly = false; SecurityHandler securityHandler = null; int status = (int)ManagementStatus.NoError; try { securityHandler = Scope.GetSecurityHandler(); status = scope.GetSecuredIWbemServicesHandler(Scope.GetIWbemServices() ).CreateInstanceEnum_(ClassName, o.Flags, o.GetContext(), ref enumWbem ); } finally { if (securityHandler != null) securityHandler.Reset(); } if (status < 0) { if ((status & 0xfffff000) == 0x80041000) ManagementException.ThrowWithExtendedInfo((ManagementStatus)status); else Marshal.ThrowExceptionForHR(status); } return new ManagementObjectCollection(Scope, o, enumWbem); }
2.Get():
下面提供一下Get()重載版本的代碼:
public ManagementObjectCollection Get() { Initialize (); IEnumWbemClassObject ew = null; SecurityHandler securityHandler = scope.GetSecurityHandler(); EnumerationOptions enumOptions = (EnumerationOptions)options.Clone(); int status = (int)ManagementStatus.NoError; try { if ((query.GetType() == typeof(SelectQuery)) && (((SelectQuery)query).Condition == null) && (((SelectQuery)query).SelectedProperties == null) && (options.EnumerateDeep == true)) { enumOptions.EnsureLocatable = false; enumOptions.PrototypeOnly = false; if (((SelectQuery)query).IsSchemaQuery == false) { status = scope.GetSecuredIWbemServicesHandler( scope.GetIWbemServices() ).CreateInstanceEnum_( ((SelectQuery)query).ClassName, enumOptions.Flags, enumOptions.GetContext(), ref ew); } else { status = scope.GetSecuredIWbemServicesHandler(scope.GetIWbemServices() ).CreateClassEnum_(((SelectQuery)query).ClassName, enumOptions.Flags, enumOptions.GetContext(), ref ew ); } } else { enumOptions.EnumerateDeep = true; status = scope.GetSecuredIWbemServicesHandler(scope.GetIWbemServices() ).ExecQuery_( query.QueryLanguage, query.QueryString, enumOptions.Flags, enumOptions.GetContext(), ref ew ); } } catch (COMException e) { // ManagementException.ThrowWithExtendedInfo(e); } finally { securityHandler.Reset(); } if ((status & 0xfffff000) == 0x80041000) { ManagementException.ThrowWithExtendedInfo((ManagementStatus)status); } else if ((status & 0x80000000) != 0) { Marshal.ThrowExceptionForHR(status); } return new ManagementObjectCollection(scope, options, ew); }
3.GetSubclasses():此方法存在四個(gè)重載版本
下面提供一下GetSubclasses(EnumerationOptions options)重載版本的代碼:
public ManagementObjectCollection GetSubclasses(EnumerationOptions options) { if (null == Path) throw new InvalidOperationException(); Initialize ( false ) ; IEnumWbemClassObject enumWbem = null; EnumerationOptions o = (null == options) ? new EnumerationOptions() : (EnumerationOptions)options.Clone(); o.EnsureLocatable = false; o.PrototypeOnly = false; SecurityHandler securityHandler = null; int status = (int)ManagementStatus.NoError; try { securityHandler = Scope.GetSecurityHandler(); status = scope.GetSecuredIWbemServicesHandler( Scope.GetIWbemServices() ).CreateClassEnum_(ClassName, o.Flags, o.GetContext(), ref enumWbem); } finally { if (securityHandler != null) securityHandler.Reset(); } if (status < 0) { if ((status & 0xfffff000) == 0x80041000) ManagementException.ThrowWithExtendedInfo((ManagementStatus)status); else Marshal.ThrowExceptionForHR(status); } return new ManagementObjectCollection(Scope, o, enumWbem); }
以上是對(duì)ManagementClass類的部分誰明,此類型的所有公共靜態(tài)成員都是線程安全的。不保證所有實(shí)例成員都是線程安全的。
二.ManagementClass類的部分應(yīng)用:
