String to DateTime Problem

Lee


Hello all,

I'm trying to solve a problem with a string to datetime conversion.
The problem arises when I try to convert a string from an XML doc into
a .net DateTime. I'm manually creating a dataset from scratch and
adding the fields and their DataTypes, appending to new datatable, etc.

I've googled extensively until the wee hours of the morning and just
can't seem to get this to work.

The format of the string is:
'02/24/2005 13:00:00'

I have tried several ways around it to no avail. If I use
DateTime.Parse( sValue); then it truncates to just a Date. Even then
the field shows as null in a DataGrid after the routine is over.

If I try:

myDateTime := DateTime.ParseE xact('mm/dd/yyyy HH:NN:SS');

...an exception is raised with Invalid DateTime Value.

I'd try:

myDateTime = DateTime.ParseE xact("MM/dd/yyyy HH:mm:ss')

Armin Zingler enlightened me by writing:

That works better, Armin. Thank you. Looks like I need to study the
formatting templates in .net a bit more.

I have a string variable that holds the equivalent of a DateTime value. I pulled this datetime from the database and I want to strip off the time portion before displaying to the user. I am using C# eg. - String variable "strMyDate" holds the value "1/1/2005 12:00:00 AM" from the database. - I do not care about the time portion, I only want "1/1/2005" for display.
