I'm trying to read in 2 columns from a DataTable that will give me a date and time. 

I've tried the line of code:

```
lastRun = DateTime.ParseExact(row["last_run_date"].ToString(), "yyyyMMdd", CultureInfo.InvariantCulture)
.Add(TimeSpan.ParseExact(row["last_run_time"].ToString().PadLeft(6, '0'), "HHmmss", CultureInfo.InvariantCulture));

```

The last\_run\_date part works OK but the time will not parse correctly.
