How to set timeout for a line of c# code [duplicate]

Answer 1

I use something like this (you should add code to deal with the various fails):

    var response = RunTaskWithTimeout(
        (Func)delegate { return SomeMethod(someInput); }, 30);


    /// 

    /// Generic method to run a task on a background thread with a specific timeout, if the task fails,
    /// notifies a user
    /// 
    /// Return type of function
    /// Function delegate for task to perform
    /// Time to allow before task times out
    /// 
    private T RunTaskWithTimeout(Func TaskAction, int TimeoutSeconds)
    {
        Task backgroundTask;

        try
        {
            backgroundTask = Task.Factory.StartNew(TaskAction);
            backgroundTask.Wait(new TimeSpan(0, 0, TimeoutSeconds));
        }
        catch (AggregateException ex)
        {
            // task failed
            var failMessage = ex.Flatten().InnerException.Message);
            return default(T);
        }
        catch (Exception ex)
        {
            // task failed
            var failMessage = ex.Message;
            return default(T);
        }

        if (!backgroundTask.IsCompleted)
        {
            // task timed out
            return default(T);
        }

        // task succeeded
        return backgroundTask.Result;
    }
