hi Dinesh datedtime will take your system format if you convert and store into datetime again you will be getting same system date format but month will go to day and vise versa so save it in string and use here you can see the differnce DateTime d1 = Convert.ToDateTime(11 / 12 / 2016); // dec month DateTime datetimeDate = Convert.ToDateTime(d1.ToString(MM/dd/yyyy)) ; // here will get november month this is wrong when you will get error when DateTime d1 = Convert.ToDateTime( 25 / 12 / 2016); day field is more than 12 string stringdate= d1.ToString(MM/dd/yyyy); //here same and output will be 12 / 111 / 2016

Now this getting complicated...(saying this to myself!) Let me try. First there is no such thing as date-time in terms of native or primary data types. The same goes with String data type. There is no such thing as String data type. It is an array of characters. Even character is nothing but an integer value. Similarly DateTime data-type is a human construct built on top of primary data type. All dates everywhere are stored as integers. This is just a wrapper to help business application developers so that don't waste time (and resources) dealing with numbers. So in summary the date format you are seeing is based just on your computer regional settings. The date is actually NOT stored in that format. You can format any DateTime type variable to any format you want just by telling it. The underlying value (which is in integer) never changes.

Vineet Kumar · Answer

you can just use ToString() method with desired format as paramater - DateTime MyDate =Convert.ToDateTime( 12/30/2016 12:00:00 ); MyDate .ToString(MM/dd/yyyy HH:mm)

If you have it in a text box it means it is in a String type. You will first need to convert it to a DateTime type (in some variable) and then use .ToString() method as stated on that variable. Hope it helps! If not please post back.

To answer your question all you have to do is use .ToString() method with an appropriate culture or format.

I don't have any code .I have a date in my textbox .I want to involve this datetime variable to some operation.For that i want to change the format @Nitin

Where exactly are you doing this? Please share some code. No formats are assigned natively to the DateTime datatype. Format are typically only for display purpose.
