How to check a field/property is existing in Win32_DiskDrive ?

taibc

Hi everyone, I am using below codes to get information from HardDisk.

ManagementObjectSearcher HardwareQuerySearcher = null;

HardwareQuerySearcher = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");

foreach (ManagementObject hard in HardwareQuerySearcher.Get())
{
Hard hdd = new Hard();
hdd.Model = hard["Model"].ToString();
hdd.Type = hard["InterfaceType"].ToString();
hdd.Type = hard["SerialNumber"].ToString();
}

Do you know how to list/or show all fields/properties that existing in this query ? For example: I am want to know wherether the field "SerialNumber" existing or not ? Thanks and regards, Tai

Thank you. Do you know what is difference between the property: SerialNumber of "Win32_PhysicalMedia" and SerialNumber of "Win32_DiskDrive" ? When I use Win32_DiskDrive, I can't get SerialNumber on Win XP Regards, Tai

Hi Simon_Whale, Do you know what are differences between the property "SerialNumber" in Win32_PhysicalMedia and Win32_DiskDrive ? Thanks and regards, Tai

As the Win32_DiskDrive document states, this property is not available on XP

Quote:

SerialNumber Data type: string Access type: Read-only Number allocated by the manufacturer to identify the physical media. Example: WD-WM3493798728 Windows Server 2003 and Windows XP: This property is not available.
