我是使用 WMI 的新手。它是什么?
例如,我可以在 C# 中使用 WMI 调用来获取我的 PC 上的驱动程序列表吗?如果是这样,我应该打电话给哪个班级?
要列出已安装的驱动程序,您可以使用Win32_PnPSignedDriver
WMI 类,如本示例所示。
using System;
using System.Collections.Generic;
using System.Management;
using System.Text;
namespace GetWMI_Info
{
class Program
{
static void Main(string[] args)
{
try
{
string ComputerName = "localhost";
ManagementScope Scope;
Scope = new ManagementScope(String.Format("\\\\{0}\\root\\CIMV2", ComputerName), null);
Scope.Connect();
ObjectQuery Query = new ObjectQuery("SELECT * FROM Win32_PnPSignedDriver");
ManagementObjectSearcher Searcher = new ManagementObjectSearcher(Scope, Query);
foreach (ManagementObject WmiObject in Searcher.Get())
{
Console.WriteLine("{0,-35} {1,-40}","ClassGuid",WmiObject["ClassGuid"]);// String
Console.WriteLine("{0,-35} {1,-40}","DeviceClass",WmiObject["DeviceClass"]);// String
Console.WriteLine("{0,-35} {1,-40}","DeviceID",WmiObject["DeviceID"]);// String
Console.WriteLine("{0,-35} {1,-40}","DeviceName",WmiObject["DeviceName"]);// String
Console.WriteLine("{0,-35} {1,-40}","Manufacturer",WmiObject["Manufacturer"]);// String
Console.WriteLine("{0,-35} {1,-40}","Name",WmiObject["Name"]);// String
Console.WriteLine("{0,-35} {1,-40}","Status",WmiObject["Status"]);// String
}
}
catch (Exception e)
{
Console.WriteLine(String.Format("Exception {0} Trace {1}",e.Message,e.StackTrace));
}
Console.WriteLine("Press Enter to exit");
Console.Read();
}
}
}
此外,如果您是 WMI 主题的新手,您可以使用类似的工具WMI Delphi Code Creator
来探索 WMI 内容并生成代码来访问 WMI。
