regex - How do I escape a single quote using C# string.Replace to use in HighCharts? -

-

in c# application using user input fill elements in highcharts. issue running when user types customer's causes application break unless escaped typing \ before '.

here section in highcharts filling in user input:

subtitle: {     text: '<%=strdescription%>' },

when adding records, instead of telling users type \ before typing ' want them automatically them when pull out of database , assign variable. here have tried:

strdescription = reader1.getstring(0); strdescription.replace("'", "\'");

when remove slash user input causes application break if string not escaped. note following error:

subtitle: {     text: 'this goal set once have bench-marked first quarter's results.' },

how escape single quote properly?

one way invert quotes - '' ""

subtitle: {     text: "<%=strdescription%>" },
