Invalid Query C#

Question

today i wrote my second Code in C# why wont it work? the code ist (as it seems) correct!

error code: InvalidQuery

Code:

  static void Main(string[] args)
      {
          GetComponent("Win32_Processor", "Name");
        Console.Read();
        Console.ReadKey();
      }

    private static void GetComponent(string hwclass, string syntax)
    {
    ManagementObjectSearcher mos = new ManagementObjectSearcher ("root\\CIMV2","SELECT * FROM" + hwclass);
    foreach(ManagementObject mj in mos.Get())
       {
           Console.WriteLine(Convert.ToString(mj[syntax]));
       }


    }  

Answer 1

Please, use formatting or string interpolation (C# 6.0+) to avoid syntax errors:

private static void GetComponent(string hwclass, string syntax) {
  //DONE: keep query readable
  string query = 
    $@"select * 
         from {hwclass}"; // <- you've missed space here

  //DONE: wrap IDisposable into using
  using (ManagementObjectSearcher mos = new ManagementObjectSearcher("root\\CIMV2", query)) {
    foreach(ManagementObject mj in mos.Get())
      Console.WriteLine(Convert.ToString(mj[syntax]));
  }
}

Answer 2

You are missing a space after the "FROM":

("root\\CIMV2","SELECT * FROM" + hwclass);

Change to:

("root\\CIMV2","SELECT * FROM " + hwclass);
