Server.MapPath specifies the relative or virtual path to map to a physical directory.
Server.MapPath(".")1 returns the current physical directory of the file (e.g. aspx) being executedServer.MapPath("..")returns the parent directoryServer.MapPath("~")returns the physical path to the root of the applicationServer.MapPath("/")returns the physical path to the root of the domain name (is not necessarily the same as the root of the application)
An example:
Let's say you pointed a web site application (http://www.example.com/) to
C:\Inetpub\wwwroot
and installed your shop application (sub web as virtual directory in IIS, marked as application) in
D:\WebApps\shop
For example, if you call Server.MapPath in following request:
http://www.example.com/shop/products/GetProduct.aspx?id=2342
then:
Server.MapPath(".")1 returnsD:\WebApps\shop\productsServer.MapPath("..")returnsD:\WebApps\shopServer.MapPath("~")returnsD:\WebApps\shopServer.MapPath("/")returnsC:\Inetpub\wwwrootServer.MapPath("/shop")returnsD:\WebApps\shop
If Path starts with either a forward (
/) or backward slash (\), the MapPath method returns a path as if Path were a full, virtual path.
If Path doesn't start with a slash, the MapPath method returns a path relative to the directory of the request being processed.
