使用WMI.Here的一个很好的起点：Administering windows machine programmatically

public static void Main()
{
  try
  {
     ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\CIMV2","SELECT * FROM Win32_SoundDevice");

     foreach (ManagementObject queryObj in searcher.Get())
     {
         Console.WriteLine("-----------------------------------");
         Console.WriteLine("List of sound cards installed");
         Console.WriteLine("-----------------------------------");
         Console.WriteLine("ProductName: {0}", queryObj["ProductName"]);
         Console.WriteLine("Availability: {0}", queryObj["Availability"]);
         Console.WriteLine("Caption: {0}", queryObj["Caption"]);
         Console.WriteLine("ConfigManagerErrorCode: {0}", queryObj["ConfigManagerErrorCode"]);
         Console.WriteLine("ConfigManagerUserConfig: {0}", queryObj["ConfigManagerUserConfig"]);
         Console.WriteLine("CreationClassName: {0}", queryObj["CreationClassName"]);
         Console.WriteLine("Description: {0}", queryObj["Description"]);
         Console.WriteLine("DeviceID: {0}", queryObj["DeviceID"]);
         Console.WriteLine("DMABufferSize: {0}", queryObj["DMABufferSize"]);
         Console.WriteLine("ErrorCleared: {0}", queryObj["ErrorCleared"]);
         Console.WriteLine("ErrorDescription: {0}", queryObj["ErrorDescription"]);
         Console.WriteLine("InstallDate: {0}", queryObj["InstallDate"]);
         Console.WriteLine("LastErrorCode: {0}", queryObj["LastErrorCode"]);
         Console.WriteLine("Manufacturer: {0}", queryObj["Manufacturer"]);
         Console.WriteLine("MPU401Address: {0}", queryObj["MPU401Address"]);
         Console.WriteLine("Name: {0}", queryObj["Name"]);
         Console.WriteLine("PNPDeviceID: {0}", queryObj["PNPDeviceID"]);
         Console.WriteLine("PowerManagementSupported: {0}", queryObj["PowerManagementSupported"]);
         Console.WriteLine("Status: {0}", queryObj["Status"]);
         Console.WriteLine("StatusInfo: {0}", queryObj["StatusInfo"]);
         Console.WriteLine("SystemCreationClassName: {0}", queryObj["SystemCreationClassName"]);
         Console.WriteLine("SystemName: {0}", queryObj["SystemName"]);
     }
 }
 catch (ManagementException e)
 {
    Console.WriteLine("An error occurred while querying for WMI data: " + e.Message);
 }
 }
