Question

How do I return web.config entry conditionally.
I.E: If the web.config folder is ‘C:\inetpub\www\myTestSite’ then return ‘connectionString’ TestDB
else return ‘ProdDB’

Answer 1

You can try something like this:

string conn;
if (Server.MapPath("~/web.config").StartsWith(@"C:\inetpub\www\myTestSite"))
    conn = ConfigurationManager.ConnectionStrings["TestDB"].ConnectionString;
else
    conn = ConfigurationManager.ConnectionStrings["ProdDB"].ConnectionString;

Although I would recommend a different approach, either by using separate config files for your sites or by using a more sophisticated method of testing where your code is located. What I do is put a key in appSettings in the machine.config file for my development machine, as well as my test, and production web servers so that my application knows what environment it is running on. I use the value of that appSetting to determine which connection string to use.
