WMIGatherer - A WMI wrapper and system information gatherer

WMIGatherer provides simple and easy WMI querying and already contains functionality to gather useful system informations.

Usage

Query Creation

If only one property of one WMI class is required:

string windowsCaption = Wmi.PropertyQuery<string>("Win32_OperatingSystem", "Caption");

• When querying a property as a primitive type (int, long, DateTime) always use nullables (int?, long?, DateTime?) in order to check if the property is null

ulong? capacity = Wmi.PropertyQuery<ulong?>("Win32_PhysicalMemory", "Capacity");

If multiple properties or multiple WMI classes are required:

string[] properties = new string[] { "Capacity", "PositionInRow" };
string condition = "PositionInRow = 1";
WmiClassCollection classCollection = Wmi.Query("Win32_PhysicalMemory", properties, condition);

If a custom query string (WQL syntax) needs to be used:

WmiClassCollection classCollection = Wmi.CustomQuery("SELECT Name, Caption FROM Win32_Bios");

What to do with WmiClassCollection

• WmiClassCollection is an ICollection of all queried classes (WmiClass)
• Each WmiClass carries its properties (WmiProperty)
• Each WmiProperty contains Name and Value
• A WmiProperty inside a WmiClass can be accessed by either:
  • iterating through WmiClass.Properties
  • using the Name property of WmiProperty as index (WmiClass["Name Of Property"])

foreach (WmiClass wmiClass in classCollection)
{
    uint? posInRow = wmiClass["PositionInRow"];
    ulong? capacity = wmiClass["Capacity"];
    // Do something with it...
}

• If the property type is primitive, it's always a nullable since a WMI property can be null

Built-In System Information Gathering

Besides the easy to use querying system, WMIGatherer offers an information gathering functionality using preset WMI queries.

• Hardware (CPU, GPU, HDD, RAM, Mainboard, HWID Creation, ...)
• Operating System (Serial Number, Caption, Architecture, ...)
• Security (Antivirus, Antispyware, Firewall)
• User (Name, FullName)
• Network (Network Adapter, MAC-Addresses, ...)

Examples

Get antivirus, antispyware and firewall product:

• SecurityProductType.AntiVirus gets antivirus software
• SecurityProductType.AntiSpyware gets antispyware software
• SecurityProductType.Firewall gets firewall applications

using WMIGatherer.Gathering;
using WMIGatherer.Enums;

// var = ICollection<SecurityProduct>
var antiviruses = SecurityGatherer.GetSecurityProducts(SecurityProductType.AntiVirus);

foreach (var av in antiviruses)
{
    string name = av.Name;
    string path = av.PathToExe;
    // Do something with it...
}

Create custom HWID:

• HwidStrength.Light uses CPU ID
• HwidStrength.Medium uses CPU ID + HDD Signature
• HwidStrength.Medium uses CPU ID + HDD Signature + BIOS Serial Number + MAC Address

using WMIGatherer.Gathering;
using WMIGatherer.Enums;

string hwid = HardwareGatherer.GetHwid(HwidStrength.Medium);
// Do something with it...

Get MAC-Address of IP enabled network interfaces:

using WMIGatherer.Gathering;

string macAddress = NetGatherer.GetActiveMacAddress();

Retrieve all RAM sticks:

using WMIGatherer.Gathering;

// var = ICollection<RamStick>
var ramSticks = HardwareGatherer.GetRamSticks();
foreach (var stick in ramSticks)
{
    ulong? capacity = stick.Capacity;
    uint? clockSpeed = stick.ClockSpeed;
    // ...
    // Do something with it...
}
