Use SQL Server time datatype in C#.NET application?
Here is an MSDN article that reviews all the new Date and Time datatypes introduced in SQL Server 2008 with respect to ADO.NET. As the document says: For System.Data.DbType.Time you would use the .NET Framework type System.TimeSpan
Also even people from Microsoft tend to recommend mapping the sql datatype time to System.Timestamp I would not recommend doing so,
since the range of sql time is 00:00:00.0000000 - 23:59:59.9999999
wheras the range of System.TimeSpan is 10675199.02:48:05.4775808 - 10675199.02:48:05.4775807
which is just slightly different and can lead to nasty runtime out of range errors.
