whats the format for a string of forward slash / in c#

Question

Hi, I'm using a htmlhelper where i give table data id's based on day and month values which are retrieved. The problem is the id is not recognized in the format it is. / seems to not be picked up yet when i replace '/' with '-' it works.

daysRow.AppendFormat("<td id='{0}/{1}'>{0}</td>", day, d1.Month.ToString());

can anyone tell me how to format this please. '/' forward slash in c#.

Answer 1

Use // iirc

alternativley i think putting @ in front of your string will make it be tret as a literal.

eg

string s = @"\w\e\r\ty";

or

string s = "d\\d";

what you need to use is the string literal

'& # 4 7 ;' without the spaces

instead of the forward slash

Answer 2

The problem is not with C#, but rather, with your using a '/' character in HTML. From the section of the HTML 4.0 spec on the id attribute:

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").

The '/' violates that rule, which is why you are seeing issues when using that, but not the '-' character.

Answer 3

I think you are using an invalid character, certainly according to this SO question it appears that you cant use forward slashes.

Answer 4

You cannot use / for ids in html. See here.
