Hi ,
i have one foreach loop which is taking currently more time and i am thinking to change to Parallel.ForEach, so is there any way to share the values of variables like <b>finalResult</b> and <b>testResult</b> among the parallel task, i.e each task get the value from shared location and update it,so that next task can pick the updated value an so on.
Could someone please help me how to achieve this?

C#

protected Data mytest(ref Check testResult, CancellationToken token, bool logOnError, bool logOnSuccess)
{
           Data finalResult = new Data(ActionStatus.Success);
            foreach (Check data in mydata.Values)
            {

                Data result = watcher.ExecuteOnce();
                Logger.Write(LogType.Info,result.Status == Success ? "succeeded" : "failed");
                finalResult = GetHighestPriority(finalResult, result, ref testResult, data);


            }
            return finalResult;
}

Thanks..

Hi
Use volatile keyword

C#

public volatile int i;

       public void Test(int _i)
       {
           i = _i;
       }
