You can use the IAsyncResult and Action class interface to achieve this   public void TimeoutExample         IAsyncResult result      Action action        gt                   Your code here             result   action BeginInvoke null  null        if  result AsyncWaitHandle WaitOne 10000            Console WriteLine  Method successful         else          Console WriteLine  Method timed out

I use something like this  you should add code to deal with the various fails        var response   RunTaskWithTimeout lt ReturnType gt            Func lt ReturnType gt  delegate   return SomeMethod someInput      30              lt summary gt          Generic method to run a task on a background thread with a specific timeout  if the task fails          notifies a user          lt  summary gt           lt typeparam name  T  gt Return type of function lt  typeparam gt           lt param name  TaskAction  gt Function delegate for task to perform lt  param gt           lt param name  TimeoutSeconds  gt Time to allow before task times out lt  param gt           lt returns gt  lt  returns gt      private T RunTaskWithTimeout lt T gt  Func lt T gt  TaskAction  int TimeoutSeconds                Task lt T gt  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

You can use the Task Parallel Library  To be more exact  you can use  Task Wait TimeSpan    using System Threading Tasks   var task   Task Run      gt  SomeMethod input    if  task Wait TimeSpan FromSeconds 10        return task Result  else     throw new Exception  Timed out
