Introduction
You may sometimes need to change your system Date format at run time. C# has namespace ‘using Microsoft.Win32
’ which helps you to change your system date and currency format.
Using the Code
First, you just have to use namespaceusing Microsoft.Win32
Then use RegistryKey
class to access Current user preferences. Then you can set value for date format using RegistryKey
’s object.
// RegistryKey rkey = Registry.CurrentUser.OpenSubKey
// (@"Control Panel\International", true);
// rkey.SetValue("sShortDate", "d/M/yy");
// rkey.SetValue("sLongDate","dd/MM/yy");
d
:Use this to specify the numeric value for the day of the month.
Eg. d (1) or dd(01) or ddd(MON) or dddd(MONDAY).M
:These display the months in numeric form.
Eg. M(1) or MM(01) or MMM(JAN) or MMMM(JANUARY).y
:Use this to specify the numeric value for the year to different digits.
Eg. y(9) or yy(09) or yyyy(2009).
t

tt
: The AM/PM designator.11/03/2011 1:45:30 PM
s

Points of Interest
This is very easy code to change system date format at runtime. Following are the class methods with their uses.// RegistryKey, represents a key-level node at windows registry
// Registry, represents a root keys in windows registry
// CurrentUser, reads windows registry base key HKEY_CURRENT_USER
You can use this code to change system currency format too.
