I was messing around with my website today, and decided I wanted sub-folder under the root (for restricted access stuff).
I didn't want to copy all of my css and javascript stuff to the sub-folder, (waste of space), so I created a new master page in the sub- folder and then went about trying to figure out how to use the script files that were off the root. In the process of finding out what not to do, I found out there were several ways to resolve a path in ASP.Net. To make it easier to test for the right method, I wrote the following code, and put it in my masterpage.master.cs file.
public partial class Restricted_MasterResticted : System.Web.UI.MasterPage
{
protected enum ResolveType { MapPath, ResolveUrl, ResolveClientUrl };
protected string ResolvePath(string relPath, ResolveType resolveType)
{
string path = relPath;
switch (resolveType)
{
case ResolveType.ResolveClientUrl : path = Page.ResolveClientUrl(path); break;
case ResolveType.ResolveUrl : path = Page.ResolveUrl(path); break;
case ResolveType.MapPath : path = MapPath(path); break;
}
return path;
}
}
I did it this way so that I could have different path resolutions for each file (if needed). I don't know if the situation will ever come up, but - well - you know...
This is what the usage looks like in the HTML:
<link rel="stylesheet" type="text/css" href="<%=ResolvePath("~/pw_styles.css", ResolveType.ResolveClientUrl) %>" />
As you can see, the correct resolve type for my case was
ResolveClientUrl
.
I've been paid as a programmer since 1982 with experience in Pascal, and C++ (both self-taught), and began writing Windows programs in 1991 using Visual C++ and MFC. In the 2nd half of 2007, I started writing C# Windows Forms and ASP.Net applications, and have since done WPF, Silverlight, WCF, web services, and Windows services.
My weakest point is that my moments of clarity are too brief to hold a meaningful conversation that requires more than 30 seconds to complete. Thankfully, grunts of agreement are all that is required to conduct most discussions without committing to any particular belief system.
