Answer 1

  backsms = backsms.Replace("\n","");

                              backsms = backsms.Replace("\n\r", "");
                              backsms = backsms.Replace("\r\n", "");//or
backsms = backsms.Remove(0, s.IndexOf('<')-1);

Answer 2

backsms = backsms.Remove(0, sbacksms .IndexOf('<')-1);
还是不灵呀，不是与字符串是utf8 编码的有关？

Answer 3

backsms.Replace("\n","");
backsms.Replace("\r", "");
backsms.Replace("\n\r", "");
backsms.Replace("\r\n", "");都没有赋值backsms = backsms.Replace("\n","");
backsms = backsms.Replace("\r", "");
backsms = backsms.Replace("\n\r", "");
backsms = backsms.Replace("\r\n", "");

Answer 4

backsms = backsms.Replace("\n","").Replace("\r", "").Replace("\n\r", "").Replace("\r\n", "");

XmlTextReader reader = new XmlTextReader(new StringReader(xmlString));
reader.WhitespaceHandling = WhitespaceHandling.None;

                              backsms = backsms.Replace("\r", "");
                              backsms = backsms.Replace("\n\r", "");
                              backsms = backsms.Replace("\r\n", "");//or

Answer 7

应该进行初始化，可以初始化为backsms = string.Empty;

Answer 8

backsms = System.Text.RegularExpressions.Regex.Replace( backsms, @"^[^<]*", "" );
这样不就搞定了

Answer 9

引用 4 楼 q107770540 的回复:
backsms = backsms.Replace("\n","").Replace("\r", "").Replace("\n\r", "").Replace("\r\n", "");正解
