Question

I have a string like this: 16:00 and I want it to be saved in my SQL Server database in a column which has a data type of time(7)…

Of course, before I save it in there, I need to convert my string in a time data type.

Upon using Convert.ToDateTime, I get an error:

Cannot implicitly convert type ‘System.DateTime’ to ‘System.TimeSpan’

That is because I am saving Convert.ToDateTime(myString) into a property of an entity from my database which has time(7) data type…

Are there other ways of converting my string into a format which is compatible with the time(7) datatype in SQL Server?

Answer 1

The managed type that corresponds to the SQL time data type is TimeSpan (or TimeSpan? when nullable), not DateTime – refer to Mapping CLR Parameter Data for the list of type conversions.

You can use TimeSpan.Parse(myString) to convert your string.
