Server.MapPath Function

Question

Why we use Server.MapPath function in Asp.Net

Mayur Gujrathi · Answer

When you need to connect to a database or a file from your webpage you'll need to know the exact file path to that particular datasource. If you aren't sure of the exact physical path then you can use Server.Mappath. Server.Mappath takes a path as a parameter and returns the exact physical location of that file on the hard drive. For the examples below, the database "mydatabase.mdb" is located in the c:\inetpub\wwwroot\database directory. The c:\inetpub\wwwroot directory is set as the web root directory. Our script uses the slash character to specify that the path returned should treated as a complete virtual path on the server and mapped from the root folder. This script outputs the following: c:\inetpub\wwwroot\database\mydatabase.mdb Because the path parameters in the following example does not start with a slash character, it is mapped relative to it's current directory, in this case c:\inetpub\wwwroot\database. This script outputs the following: c:\inetpub\wwwroot\database\mydatabase.mdb So in a nutshell the MapPath method maps the specified relative or virtual path to the corresponding physical directory on the server.

The Server.MapPath() method helps to map the given virtual path to absolute path. It can be used to locate absolute file paths for file input output. Eg: Server.MapPath("~/Images") will give c:\inetpub\wwwroot\yourwebapp\images as the folder (provided the application is hosted in the above folder)
