c# - Backslash using for escaping qute regenerate after asigning String -

in tostring methode of entity, try generate informational string includes quotes. use backslash before quote , until try assign return value string variable , after backslash comeback .here tostring function:

public override string tostring()     {         string content = "{";         content += "\"servicetype\":" + servicetype.name + ",";         content += "\"debt\":" + amount;         content += "}";         return content;     } 

after try use stringwriter , htmltextwriter generate html after assign return value string variable there lot of \, \r, \n, \tin variable.here function:

    public string tohtmlstring()     {          stringwriter stringwriter = new stringwriter();         using (htmltextwriter writer = new htmltextwriter(stringwriter))         {             writer.addstyleattribute(htmltextwriterstyle.width, "100%");             writer.addstyleattribute(htmltextwriterstyle.borderstyle, "1px solid black");             writer.addstyleattribute(htmltextwriterstyle.direction, "rtl");             writer.renderbegintag(htmltextwritertag.table);// begin table              writer.renderbegintag(htmltextwritertag.tr);             writer.renderbegintag(htmltextwritertag.td);             writer.write("زیر خدمت");             writer.renderendtag();             writer.renderbegintag(htmltextwritertag.td);             writer.write(servicetype.name);             writer.renderendtag();             writer.renderendtag();              writer.renderbegintag(htmltextwritertag.tr);             writer.renderbegintag(htmltextwritertag.td);             writer.write("مبلغ");             writer.renderendtag();             writer.renderbegintag(htmltextwritertag.td);             writer.write(amount);             writer.renderendtag();             writer.renderendtag();              writer.renderendtag();// end table         }         return stringwriter.tostring();     } 

and after assigning value variable:

<table style=\"width:100%;border-style:1px solid black;direction:rtl;\">\r\n\t<tr>\r\n\t\t<td>زیر خدمت</td><td>درمان</td>\r\n\t</tr><tr>\r\n\t\t<td>مبلغ</td><td>6000</td>\r\n\t</tr>\r\n</table> 

what's happening here?

that result seems ok use in webbrowser control inside c#. if prefer avoid these newlines , tabs (for real browser), can try replacing few lines of code this.

old code:

using (htmltextwriter writer = new htmltextwriter(stringwriter))     { 

new code:

using (htmltextwriter writer = new htmltextwriter(stringwriter, string.empty))     {         writer.newline = string.empty; 

the second parameter in htmltextwriter string used tab. result like:

<table style=\"width:100%;border-style:1px solid black;direction:rtl;\"><tr><td>زیر خدمت</td><td>درمان</td></tr><tr><td>مبلغ</td><td>6000</td></tr></table> 

edit: in order avoid \" use <? php echo or <%=(for asp), or better rework result as:

return stringwriter.tostring().replace("\"", "'");
