Get absolute path of relative path

Question

I am calling a method in C# as follows:

return Chart.RenderChartHTML("../../Charts/MSLine.swf");

The thing is that the path can be different depending on what folder I am calling RenderChartHTML from.

I tried the following so that it finds the absolute path but not working:

string mslinepath = HttpContext.Current.Server.MapPath("~/Charts/MSLine.swf");

return Chart.RenderChartHTML(mslinepath);

Does this help? http://stackoverflow.com/questions/837488/how-can-i-get-the-applications-path-in-net-in-a-console-app — Joe, Nov 07 '12 at 17:46

You don't need the ~/. Just HttpContext.Current.Server.MapPath("Charts/MSLine.swf");

Use ResolveUrl(). It converts a URL into one that is usable on the requesting client.

So Try this instead :

string mslinepath = ResolveUrl("~/Charts/MSLine.swf")

Hope this will help !!

Thanks. Why do I need the ~ for though? – Nate Pet Nov 07 '12 at 18:17

"~" refers get the relative path from "root" directory and "." refers get the relative path from current directory. – Kundan Singh Chouhan Nov 07 '12 at 18:20
