Example

[C#] 
using System; 
using System.Management; 

// This example shows how to obtain meta data 
// about a WMI method with a given name in a given WMI class 

class Sample_MethodData 
{ 
    public static int Main(string[] args) { 

        // Get the "SetPowerState" method in the Win32_LogicalDisk class 
        ManagementClass diskClass = new ManagementClass("win32_logicaldisk");
        MethodData m = diskClass.Methods["SetPowerState"];
      
        // Get method name (albeit we already know it)
        Console.WriteLine("Name: " + m.Name);

        // Get the name of the top-most class where this specific method was defined
        Console.WriteLine("Origin: " + m.Origin);
      
        // List names and types of input parameters
