Converting DOS date to mmddyyyy format in C#

[spdude]

I am working on an application that stores date in DOS format. For ex:
9540 which appears to be the number of days since 1980. Anyone knows a
way to convert this into the mmddyyyy format?

Thanks in advance.

How about

new DateTime(1980, 1, 1).AddDays(yourDateValue).ToString("MMddyyyy");

Just create a different class with static methods

public class DOSDateTimeFormat
{
public static DateTime ConvertFrom(string dt_value)
{
return new DateTime(1980, 1, 1).AddDays(dt_value);
}

public static string ConvertTo(DateTime dt)
{
return ( dt.Subtract(new DateTime(1980, 1, 1))
).ToString("MMddyyyy");
}
}

That way it can be reusable and you can put the class in a utility
assembly.

Sincerely,

Does
DateTime.FromOADate( <double> )

do it for you? It takes a date as a double (number of days since...) and
converts it to a DateTime.
