I have done a web project ( using C# + SQL CE + ASP.NET )where it does few manupulation with .sdf file and results are displaye via ASP.net page . While i started working I hardcoded the path of the connection string and worked in my system . Now I want this database to be residing inside my server page.

How do i get the working directory( localhost) so
that i can put that in connection
string ?

I tried using

System.Environment.CommandLine but it throws me a error saying 

"Format of the initialization string does not conform to specification starting at index 98." The outcome of System.Environment.CommandLine is

Data Source= "C:\Program Files\Common Files\Microsoft Shared\DevServer\9.0\WebDev.WebServer.EXE" /port:1438 /path:"C:\Documents and Settings\xxx\Desktop\Project\yyy\Deploy\EMSWEB\Back010\WEB\WEB" /vpath:"/WEB"/tEST.sdf;Persist Security Info=True;

Any idea ???

    I finally made it work using 

    connectionString="data source=|DataDirectory|\test.sdf"

    where as

     Data Source=" + (System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase) + "\\

    Points to some directory like this below.

    C:\Program Files\Common Files\Microsoft Shared\DevServer\9.0\WebDev.WebServer.EXE" /port:1438 /path:"C:\Documents and Settings\xxx\Desktop\Project\yyy\Deploy\EMSWEB\Back010\WEB\WEB" /vpath:"/WEB"/tEST.sdf
