I’m working on an API for getting System Information easily in C#, albeit i’m pretty sure that one already exists, but I like creating my own stuff. I’m coming from JavaScript and Java. So I don’t really know if my approach for certain things in the API is good or not so much. What do you think?

// Dict for storing the needed ManagementObjectSearchers for easy access     private Dictionary<string, ManagementObjectSearcher> wmiSearchers;      public SystemMonitor() {          this.wmiSearchers = new Dictionary<string, ManagementObjectSearcher>();          string[] wmiClasses = {             "Win32_Processor",             "Win32_DiskDrive",             "Win32_PhysicalMemoryArray"                         };          foreach (string wmiClass in wmiClasses) {             this.wmiSearchers.Add(wmiClass, new ManagementObjectSearcher(String.Format("SELECT * FROM {0}", wmiClass)));         }      }      // Utility method for getting the ManagementObjectCollection results as a List     static List<ManagementBaseObject> _searcherAsList(ManagementObjectSearcher s)     {         List<ManagementBaseObject> tmp = new List<ManagementBaseObject>();         foreach (var obj in s.Get()) {             tmp.Add(obj);         }         return tmp;     }      // Utility method for getting a property name from a wmiClass (for the given index)     private string getValueFrom(string wmiClass, string propName, int itemIndex = 0)     {         return _searcherAsList(this.wmiSearchers[wmiClass])[itemIndex][propName].ToString();     }       #region CPU_INFORMATION      // Get the number of available cpus     public int getNumberOfCpus()     {         return _searcherAsList(this.wmiSearchers["Win32_Processor"]).Count;     }      // Get the OVERALL cpu usage for the given cpu.     public double getOverallCpuUsage(int cpuIndex = 0) {         return Double.Parse(this.getValueFrom("Win32_Processor", "LoadPercentage"));     }      // Get the number of physical cores for the given cpu.     public double getCpuPhysicalCoreCount(int cpuIndex = 0)     {         return int.Parse(this.getValueFrom("Win32_Processor", "NumberOfCores", cpuIndex));     }      // Get the number of logical cores for the given cpu     public double getCpuLogicalCoreCount(int cpuIndex = 0)     {         return int.Parse(this.getValueFrom("Win32_Processor", "NumberOfLogicalProcessors", cpuIndex));     }
