How do I run a simulation by using c#?

edit

Here is my translation of the ruby project to c#.

• Step 1: Variables
• Step 2: Create IDF
• Step 3: Start RunManager
• Step 4: Found EnergyPlus.exe File
• Step 5: Simulation

• Step 6: Read SQL File

     //_path must be your Folder of Saving the Project z.B. C://OpenStudio//Projects//...
      string e _runDirStr =_path + "\\run";
      string _sqlPathStr = _runDirStr + "\\EnergyPlus\\eplusout.sql";
      string _epDirStr = "C:\\EnergyPlusV8-4-0";
      string _epPathStr = _epDirStr + "\\energyplus.exe";
      string idd_pathStr = _epDirStr + "\\Energy+.idd";
      string  outputPathStr = _runDirStr;
  
      Path _epPath = new Path(_epPathStr);
      Path _sqlPath = new Path(_sqlPathStr);
  
      System.IO.Directory.CreateDirectory(_path);
      System.IO.Directory.CreateDirectory(_runDirStr);
  
      SimulationControl control = _model.getSimulationControl();
      control.setDoPlantSizingCalculation(true);
      control.setDoZoneSizingCalculation(true);
      control.setRunSimulationforSizingPeriods(false); //do not use DesignDays
      control.setRunSimulationforWeatherFileRunPeriods(true); //use Weatherfile
  
      //Export IDF
      string idf_name, osm_name;
      idf_name = "simulation_in.idf";
      osm_name = "simulation_ThesisModel.osm";
      EnergyPlusForwardTranslator translator = new EnergyPlusForwardTranslator();
      Workspace idf = translator.translateModel(_model);
      //IdfFile idf_file =  _model.toIdfFile();
      _idfPathStr = _runDirStr + "\\" + idf_name;
      osmPathStr = _runDirStr + "\\" + osm_name;
      idf.save(new Path(_idfPathStr),true);
      _model.save(new Path(osmPathStr), true);
  
      //Runmanager
      Path runManagerPath = new Path(_runDirStr + "\\simulation_runmanager.db");
      RunManager run = new RunManager(runManagerPath, true, false, false, false);
      ToolInfo tool = new ToolInfo(_epPath);
      Job job = JobFactory.createEnergyPlusJob(tool, new Path(idd_pathStr), new Path(_idfPathStr), _weatherFilePath, new Path(outputPathStr));
      run.enqueue(job, true);
      run.setPaused(false);
      run.workPending();
  
      //start Simulation
      //run.runWorkflow(new Path(job.toJSON()),new Path(_idfPath),new Path(_runDir), new Tools(),"");
      Workflow sim = new Workflow(job);
      sim.create(new Path(outputPathStr), new Path(new Path(_idfPathStr)));
  
      //read results
      if (System.IO.File.Exists(_sqlPathStr))
      {
          _model.setSqlFile(new SqlFile(_sqlPath));
      }
