How can i remove all the forward slash "/", Colons ":" and spaces from DateTime.-CodePudding

I want to convert DataTime.Now output into a interger,

I want to remove all the forward slash "/" Colons ":" and spaces " " even PM/AM.

example:

From = 1/24/2022 10:51:54 PM

to = 1242022105154

CodePudding user response：

Use this :

long n = long.Parse(date.ToString("yyyyMMddHHmmss"));

if you want in string format :

var n = date.ToString("yyyyMMddHHmmss");

And you can change the location of the year and month in the above field. for example :(this is correct for your question)

var n = date.ToString("MddyyyyHHmmss");

where date is your variable contain date value.

CodePudding user response：

If you have a date-string you first need to parse it, then you can use DateTime.ToString:

string s = "1/24/2022 10:51:54 PM";
string result = DateTime.Parse(s, CultureInfo.InvariantCulture).ToString("MdyyyyHHmmss");

So the correct format string for you is MdyyyyHHmmss.

Note that m are minutes and M is month, uppercase H means 24h hours.

See: Custom date and time format strings

CodePudding user response：

string outPut= DateTime.Now.ToString("MdyyyyHHmmss", CultureInfo.InvariantCulture);

The Path .GetFileNameWithoutExtension method gives you the filename you pass as an argument without the extension, as should be obvious from the name.

CodePudding user response：

You can use as below:

From.ToString().Replace("/","").Replace(":","").Replace(" ","")

CodePudding user response：

You can use :

.Replace("the character u want to remove" , "new char");
