private async Task Test()
{
         await Task.Run(() =>
         {
             try
             {
                  DoingSomething();
             }
             catch (Exception ex)
             {
                  log.Error(ex.Message);
             }
         });
 
}

但是,由于您正在等待该任务,所以最有可能的是,在Test方法中会有一些DoSomethingElse,这可能会受到Task的结果的影响 – 在这种情况下,等待一个try / catch也是有意义的.

private async Task Test()
{
     try
     {
         await Task.Run(() =>
         {
             try
             {
                  DoingSomething();
             }
             catch (SomeSpecialException spex)
             {
                  // it is OK to have this exception
                  log.Error(ex.Message);
             }
         });
 
         DoSomethingElse(); // does not run when unexpected exception occurs.
      }
      catch (Exception ex)
      {
          // Here we are also running on captured SynchronizationContext
          // So,can update UI to show error ....
      }
}
