Hello All,

I am trying to set a date as "01/01/1900" in the initializer of a class.
For this I am using following code:

C#

private DateTime Delivery_Date = DateTime.ParseExact("01/01/1900", "MM/dd/yyyy", null);

This throws error.
My Systems date format is dd-MM-yyyy.
When I change the System date format from dd-MM-yyyy to dd/MM/yyyy. The above code works fine.

Please help.

Thanks,
Nitin

Why are you parsing a datetime to a datetime?

Why not use:

C#

private DateTime Delivery_Date = new DateTime(1900, 1, 1);

It works but still not clear, Why it is not parsing the date properly if I am providing the format.

Simple, all you had to do was read the documentation:
http://msdn.microsoft.com/en-us/library/w2sa9yss.aspx
Which says:
"If provider is null, the CultureInfo object that corresponds to the current culture is used."

Since you don't specify InvariantCulture, your local setting takes priority.
Though it doesn't throw an error on my system, and my date format is dd/MM/yyyy, so that part may be due to your .NET environment being different in some way from mine.
It does seem rather wasteful to parse a constant string to generate a initial value anyway! :laugh:

Hello,
Please try this

DateTime myDt = DateTime.ParseExact("1900-01-01", "yyyy-MM-dd",
                                       System.Globalization.CultureInfo.InvariantCulture)
