c#中如何替换换行符
stringstrpageContent=strpageContent.Replace("\r\n","");
这种方式好像无法正确替换

Answer 1

替换固定字符没必要用正则表达式，效率差。stringstr="line1\r\nline2\nline3\r";str=str.Replace(System.Environment.NewLine,"");//OKstr=str.Replace("\r","").Replace("\n","");//也OK

Answer 2

stringpattern=@"\r*\n";Regexrgx=newRegex(pattern);stringoutputStr=rgx.Replace(strpageContent,"");
