• Use WMI to get Processor Information in C#

    Posted on October 24, 2012 by in Dotnet Tips & Tricks, Tips & Tricks

    We use ManagementObjectSearcher to execute the given query to get the list of management objects that matches the select criteria.  When instantiated, an instance of this class takes as input a WMI query represented in an ObjectQuery and execute the query in. When the Get method on this object is invoked, the ManagementObjectSearcher executes the given query in the specified scope and returns a collection of management objects that match the query.

    public static void RetrieveProcessorInfo()
    {
        //initialize the select query with command text
        SelectQuery query = new SelectQuery(@"Select * from Win32_Processor");
    
        //initialize the searcher with the query it is supposed to execute
        using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(query))
        {
            //execute the query
            foreach (ManagementObject process in searcher.Get())
            {
                //print process properties
                Console.WriteLine("/*********Processor Information ***************/");
               Console.WriteLine("{0}{1}", "Manufacturer:" , process["Manufacturer"]);
               Console.WriteLine("{0}{1}", "Name:", process["Name"]);
               Console.WriteLine("{0}{1}", "MaxClockSpeed:", process["MaxClockSpeed"]);
               Console.WriteLine("{0}{1}", "ProcessorID:", process["ProcessorID"]);
               Console.WriteLine("{0}{1}", "Revision:", process["Revision"]);
            }
        }
