Yes, debugger displays strings that way. But it doesn't mean there are two backslashes. Did you try to print the string to console? It will be correct.

C# donot allow to put single \ when i take output its is single \ but when i assign value on server side it reamains "dd\\/mm\\/yyyy" i just want to convert this into -> dd\/mm\/yyyy i dnnt have to print i just have to assign value on server side and then post not have to print.

Last replace in your question does notmake sense as you remplace one backslash by one backslash!

As mentionned by other, the debugger shows \\ for backslash but you can open the text visualizer which write the text as it. It is then easier to figure out the final string if there is a lot of backslashes.

By the way, it is hard to understand your question as we cannot make sense of it as the text should be what you say it would.

Solution 1

Date has no special Format - it isn't a string.
If you want a string, which Displays your Date in a special way you could use the toString-Command of Date. Here you could build up your Output-String as you want.

C#

myString = myDate.toString("MMMM mm.yyyy") ;

... or what you want.
Refer the decription of the toString-Placeholders ...

Solution 2

What are you trying to do with the resulting string? The following code should work:

C#

string date = dy + "\\/" + mn + "\\/" + yy;

Alternatively if your values are already in a DateTime object you could just use:

C#

string date = sDate.ToString("dd\\\\/MM\\\\/yy");

// or

string date = sDate.ToString(@"dd\\/MM\\/yy");

Hi Richard Thanks for yours reply i tried all this but c# donot allow \ this because it is a escape character so while when i try to format in yours manner its shows error.

Richard MacCutchan 21-May-15 4:49am

Sorry, bad formatting above, now fixed. You need to use a double backslash in each position.

Naveen Singh 21-May-15 5:15am

HI Richard thanks for yours response but still iam getting 19\\//5\\//1990 this format value.my code is
DateTime datevalue = Convert.ToDateTime(sDate.ToString());

String dy = datevalue.Day.ToString();
String mn = datevalue.Month.ToString();
String yy = datevalue.Year.ToString();
string date = dy + "\\" + "//" + mn + "\\" + "//" + yy;

Richard MacCutchan 21-May-15 5:32am

Yes, my apologies I should remember that the ToString method interprets the backslashes so you need either the '@' prefix, or four backslashes. Use the second or third version as above; there is no point in extracting the day, month and year and converting them to strings when ToString does it all for you.

doesnt work for me :(

Richard MacCutchan 21-May-15 7:53am

Please edit your original question and show us the exact code that you are using, and explain what doesn't work. We cannot guess what you are doing.

Richard MacCutchan 21-May-15 5:40am

Your code seems unnecessarily complicated. Why convert a date to a string, just so you can parse it back into a date, just so you can extract each component and convert them to strings, so you can then concatenate them into a new string?

Naveen Singh 21-May-15 6:01am

but i cannot cocatinate \ as its not allowed in c#

Richard MacCutchan 21-May-15 7:50am

Yes it is, I just tried it. But why will you not use the easy solutions that I posted for you?
