ADO.NET :: Convert Timespan To Datetime?

Aug 17, 2010

I am getting time span paramter from our client apllication(in 3.5 using C#).

When i am Saving this Timepan Parameter at Our Backend (Sql server 2008) Using Linq(In WCF Service) it gives following error:

Unable to cast object of type 'System.TimeSpan' to type 'System.IConvertible'.

My Code is given below:

objsession.s_QuestionMasterTopicInsert(topic.Title, contentId,
topic.IsAvailable, ref strRet,
ref strRetMsg);
// topic.Time(is the time span type )
//I changed Convert.ToDateTime(Time) to
objsession.s_QuestionMasterTopicInsert(topic.Title, contentId, new
DateTime(time.Ticks), topic.IsAvailable,
ref strRet,
ref strRetMsg);

But it gives following error:

SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM

Is it Possible to convert timespan to Datetime?

How should I save timespan at My backend as Datetime Field ?

C# - TimeSpan For Different Years Substracted From A Bigger TimeSpan?

Feb 9, 2011

The language I am using is C#.

I have the folowing dillema.

DateTime A, DateTime B. If A < B then I have to calculate the number of days per year in that timespan and multiply it by a coeficient that corresponds to that year.
My problem is the fact that it can span multiple years.

For example:

Convert DateTime To Shortdatetime In C#?

May 8, 2010

I have a column in my datatable which is of DateTime Type. I only want the DatePart, hence when I use the ToShortDateTimeString it converts to short date but of string type. Hence when i reassign the string to the column of the datatable it again appends 12:00:00 to it. I cannot change the column type in my datatable. Is there any way to convert DateTime to ShortDateTime directly without converting to string?

i know that we can do this e.g.

dim str as String = textbox1.text ' when date is in this format dd/MM/yyyy
dim date_time as Datetime = Date.ParseExact( str , "dd/MM/yyyy" , nothing)

I've been googling for a while now and for the life of me can't seem to find a solution. I thought this would be easy but it's taking too long and am turning to stackoverflow.

I need to convert a string which contains a date and time to a DateTime variable. I've formatted the string in the exact format I want to store it in but when i convert it to a DateTime it keeps adding the seconds which I don't want. I want it stored as 01/01/2010 09:00AM. Here's the code I've been using so far:
