获得相对路径的绝对路径

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);

Answer 1

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 !!

Answer 2

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