c# - How can I add a blank line to my StringBuilder? -

it known "issue" doing this:

sb.appendline(); 

...will not add blank line, 1 expect (as discussed here, instance).

however, commonly believed work:

sb.appendline(environment.newline); 

...but it's not working me. i've got code:

for (int = 0; < listoflistitems.count; i++) {     sb.appendline(environment.newline);     lc = listoflistitems[i];     sb.appendline(string.format(@"<p>request date {0}; payee name {1}; remit address or mail stop {2}; last 4 of ssn or itin {3}; 204 submitted or on file {4}; requester name {5}; dept or div name {6}; phone {7}; email {8}</p>",         lc.li_requestdate, lc.li_payeename, lc.li_remitaddressormailstop, lc.li_last4ssndigitsoritin, lc.li_204submittedoronfile, lc.li_requestername, lc.li_deptdivname, lc.li_phone, lc.li_email)); } 

all data being added stringbuilder, , form gets generated, there no spaces between list items - "sb.appendline(environment.newline)" appending nothing.

what must force line between individual list item outputs?

the stringbuilder.appendline add \r\n end of string. not need explicitly add statement stringbuilder.appendline(system.environment.newline). can cross check converting string returned stringbuilder array of chars, can see newlines.

in example, looks trying display output in html (looking @ p tag in string) , newline not visible in html. in order achieve this, may want add br string.

sb.appendline("<br/>"); 

a carriage return (\r\n) has no meaning within html tags.
