字符串==问题

Question

在c#中，
http://www.jxedi.com/bbs/dispbbs.asp?boardid=6&replyid=35567&id=2090&page=1&skin=0&Star=2
http://www.jxedi.com/bbs/dispbbs.asp?boardid=6&replyid=35567&id=2090&page=1&skin=0&Star=2
这两个字符串，明明是相同的，为什么if（“http://www.jxedi.com/bbs/dispbbs.asp?boardid=6&replyid=35567&id=2090&page=1&skin=0&Star=2
”＝＝“http://www.jxedi.com/bbs/dispbbs.asp?boardid=6&replyid=35567&id=2090&page=1&skin=0&Star=2
”）不成立啊

Answer 1

bool same = "http://www.jxedi.com/bbs/dispbbs.asp?boardid=6&replyid=35567&id=2090&page=1&skin=0&Star=2"=="http://www.jxedi.com/bbs/dispbbs.asp?boardid=6&replyid=35567&id=2090&page=1&skin=0&Star=2";
这个运行结果为true
LZ是不是把半全角写错了..你上面的有些是全角..

string s = "http://www.jxedi.com/bbs/dispbbs.asp?boardid=6&replyid=35567&id=2090&page=1&skin=0&Star=2";
            string s1 = "http://www.jxedi.com/bbs/dispbbs.asp?boardid=6&replyid=35567&id=2090&page=1&skin=0&Star=2";

string s = @"http://www.jxedi.com/bbs/dispbbs.asp?boardid=6&replyid=35567&id=2090&page=1&skin=0&Star=2";
string s1 = @"http://www.jxedi.com/bbs/dispbbs.asp?boardid=6&replyid=35567&id=2090&page=1&skin=0&Star=2";
