谁能帮助我找到用于检索硬件地址和IRQ的WMI方法?
到目前为止,我看过的类似乎有些空白,无法告诉您实际使用资源的设备是什么,但是如果Windows的“系统信息”工具下有可用的设备,则必须是可行的。
最终,我想在C#应用程序中创建地址映射和IRQ映射。
我简要地看了以下几类:
Win32_DeviceMemoryAddress
Win32_IRQResource
而我只是这一秒钟看到了另一个,但是我还没有真正研究它:
Win32_AllocatedResource
也许与Win32_PnPEntity配对?
最佳答案
要获取该信息,您必须使用ASSOCIATORS OF
WQL句子在
Win32_DeviceMemoryAddress-> Win32_PnPEntity-> Win32_IRQResource类。
检查此示例应用
using System;
using System.Collections.Generic;
using System.Linq;
using System.Management;
using System.Text;
namespace WMIIRQ
{
class Program
{
static void Main(string[] args)
{
foreach(ManagementObject Memory in new ManagementObjectSearcher(
"select * from Win32_DeviceMemoryAddress").Get())
{
Console.WriteLine("Address=" + Memory["Name"]);
// associate Memory addresses with Pnp Devices
foreach(ManagementObject Pnp in new ManagementObjectSearcher(
"ASSOCIATORS OF {Win32_DeviceMemoryAddress.StartingAddress='" + Memory["StartingAddress"] + "'} WHERE RESULTCLASS = Win32_PnPEntity").Get())
{
Console.WriteLine(" Pnp Device =" + Pnp["Caption"]);
// associate Pnp Devices with IRQ
foreach(ManagementObject IRQ in new ManagementObjectSearcher(
"ASSOCIATORS OF {Win32_PnPEntity.DeviceID='" + Pnp["PNPDeviceID"] + "'} WHERE RESULTCLASS = Win32_IRQResource").Get())
{
Console.WriteLine(" IRQ=" + IRQ["Name"]);
}
}
}
Console.ReadLine();
}
}
}
