Server.MapPath("/") doesnt work

M

MichiMichi

When using Server.MapPath on IIS 5 on my localhost everything works
well. All of the following commands are executed without any error

Response.Write(Server.MapPath("/app_test") & "<br>")
Response.Write(Server.MapPath("app_test") & "<br>")
Response.Write(Server.MapPath("~") & "<br>")

However, running the first statement on via the internal Visual Studio
2005 Server I receive an error for

Server.MapPath("/app_test")

Source File: C:\Documents and Settings\machine.namei\My Documents
\Visual Studio 2005\WebSites\testing\phishingPics\Default2.aspx.vb
Line: 10

Stack Trace:


[InvalidOperationException: Failed to map the path '/app_test'.]
System.Web.Hosting.HostingEnvironment.MapPathActual(VirtualPath
virtualPath, Boolean permitNull) +3521356
System.Web.VirtualPath.MapPathInternal() +41
System

What can I do to make this work on my testing enviroment with the
light weight webserver on Visual Studio 2005
 
?

Do you need to use that exact path? What folder is it that you want to
reach?

I want to reach the root folder of my web application.

Response.Write(Server.MapPath("~") works fine but I thought it also
would work with Response.Write(Server.MapPath("/") but it doesnt?

It works on IIS but not with the intern web server of VS2005

Why not use the method that works? The old method doesn't work because a
path beginning with a forward-slash is a site-root relative path. An ASP.Net
application is not a (web) site root. It is simply a designation of a
virtual directory as housing resources that will be processed in the same
application domain (memory space). The tilde ('~') indicates that the path
is relative to the application root.

I want to reach the root folder of my web application.

Then you should use "~", not "/".

If you use "/" you will get to the root folder of the web site, but if
your application is in a virtual folder, you will get the wrong address.

I am now using the "~" instead of "/".

Microsoft should change its documentation as well.

Thanks for helping.
