Rename a printer using C-sharp (C#)

WMI provides an easy way to manage system resources such as printers, scanners, processes etc. In the example below, I show how to rename a printer using a WMI query in c#:

    private void RenamePrinter(string oldName, string newName)
    {
      ManagementObjectSearcher query = new ManagementObjectSearcher(
        "SELECT * FROM Win32_Printer");

      ManagementObjectCollection result = query.Get();

      foreach (ManagementObject printer in result)
      {
        if (printer["name"].ToString() == oldName)
        {
          printer.InvokeMethod("RenamePrinter",
                               new object[] { newName });
          return;
        }
      }
    }

In a similar way, one can change a default printer:

    private void SetDefaultPrinter(string printerName)
    {
      ManagementObjectSearcher query = new ManagementObjectSearcher(
        "SELECT * FROM Win32_Printer");

      ManagementObjectCollection result = query.Get();

      foreach (ManagementObject printer in result)
      {
        if (printer["name"].ToString() == printerName)
        {
          printer.InvokeMethod("SetDefaultPrinter",
                               new object[] {printerName});
          return;
        }
      }
    }
