VB.NET如何调用WMI来实现系统管理和系统信息查询

这篇文章给大家分享的是有关VB.NET如何调用WMI来实现系统管理和系统信息查询的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。

VB.Net调用WMI可以实现系统管理和系统信息查询等。WMI全称为Windows Management Instrumentation，利用WMI我们可以实现很多系统管理的功能，msdn在.Net Framework类库中对此描述比较简单（因为早期WMI相关专题有所较详尽描述，故类库中未再详细解说与演示）。

开发环境： VB2005 Windows2003

本实例需要在菜单栏中的"项目"-" 添加引用" -" System.Management"并在实例代码中导入引用的项目和程序集中定义的命名空间或编程元素 即： Imports System.Management

代码如下：

Private Sub Lobdotcn()  Dim Lob_Searcher As New ManagementObjectSearcher("root\CIMV2", "SELECT * FROM Win32_BootConfiguration")  For Each Obj_Query As ManagementObject In Lob_Searcher.Get()  ListBox1.Items.Add("乐博网LOB.Cn   VB.Net爱好者的组织")  ListBox1.Items.Add("BootDirectory: " & Obj_Query("BootDirectory"))  ListBox1.Items.Add("Caption: " & Obj_Query("Caption"))  ListBox1.Items.Add("ConfigurationPath: " & Obj_Query("ConfigurationPath"))  ListBox1.Items.Add("Description: " & Obj_Query("Description"))  ListBox1.Items.Add("LastDrive: " & Obj_Query("LastDrive"))  ListBox1.Items.Add("Name: " & Obj_Query("Name"))  ListBox1.Items.Add("ScratchDirectory: " & Obj_Query("ScratchDirectory"))  ListBox1.Items.Add("SettingID: " & Obj_Query("SettingID"))  ListBox1.Items.Add("TempDirectory: " & Obj_Query("TempDirectory"))  Next  End Sub

相关属性说明：

BootDirectory   Data type: string  Access type: Read-only   Path to the system files required for booting the system.  Example: "C:\Windows"  Caption   Data type: string  Access type: Read-only  Qualifiers: MaxLen(64)   Short description (one-line string) of the CIM_Setting object. This property is inherited from CIM_Setting.  ConfigurationPath   Data type: string  Access type: Read-only   Path to the configuration files. This value may be similar to the value in the BootDirectory property.  Description   Data type: string  Access type: Read-only   Description of the CIM_Setting object. This property is inherited from CIM_Setting.  LastDrive   Data type: string  Access type: Read-only   Last drive letter to which a physical drive is assigned.  Example: "E:"  Name   Data type: string  Access type: Read-only  Qualifiers: Key, MaxLen(256)   Name of the boot configuration. It is an identifier for the boot configuration.  ScratchDirectory   Data type: string  Access type: Read-only   Directory where temporary files can reside during boot time.  SettingID   Data type: string  Access type: Read-only  Qualifiers: MaxLen(256)   Identifier by which the CIM_Setting object is known. This property is inherited from CIM_Setting.  TempDirectory   Data type: string  Access type: Read-only   Directory where temporary files are stored.  Example: "C:\TEMP"
