Convert a string to a datetime using a pattern

[Iwan Petrow]

Hi,

I have a string which represent a date as follow: "dd-.MM-.yyyy hh:mm".
How could I convert this string to DateTime type (I prefer somehow to
set this as a pattern if it is possible because I have other
possibilities as "dd~MM~yyyy , hh:mm")?

Thanks.

string myString = "1-1-2000";
DateTime myDateTime = DateTime.Parse( myString);

Hope this helps,
Arjen

DateTime.Parse( ...)

Thanks.

But I want culture invariant.

I've found a class DateTimeFormatI nfo which is good enough but I want
to forbid AM and PM. I use HH but it doesn't work (it accepts them).

Any ideas for forbidding them (AM and PM)?

Hi,

One of the overloads of DateTime.ParseE xact does it:

DateTime.ParseE xact( "31-.12-.2005 23:51", "dd-.MM-.yyyy hh-.mm" ,
DateTimeFormatI nfo.InvariantIn fo );

Note:
I wrote the above line from memory, it may have some error in the format,
check it first, also note that the casing is important MM=month and
mm=minutes

Cheers,

In that case, pass the invariant culture into DateTime.ParseE xact.

Have you tried using ParseExact rather than just Parse?

It works in most cases. But for this there is a problem:
DateTime.ParseE xact( "31\\12\\20 05", "dd\\MM\\yy yy" ,
DateTimeFormatI nfo.InvariantIn *fo );

It throws exception with message "string is not a date" or something
similar.
Why? Any solutions?

Hi,

haa , tricky one :) , but easy to explain

if you look the help of DateTimeFormatI nfo you will see at the botton that
there is a \c variant :
\ c Where c is any character. Displays the character
literally. To display the backslash character, use "\\".

So, if you change the expression to:

DateTime d = DateTime.ParseE xact( @"31\12\2005 ", @"dd\\MM\\yy yy" ,
DateTimeFormatI nfo.InvariantIn fo );

you will be ok, see that I use the @ at the start, IMO it's clearer that
using two \
