.sln file lost, then how to run a project which has a database connection?

asp.net, c#

Solution

Go to file-> New Project in Visual Studio. Then go to "Other Project Types"-> "Visual Studio Solutions". You should see "Blank Solution". Just create a blank solution. Once you have that right click on the solution and go to "Add"->"Existing Project" and select your projects.

Problem

I have created a project of Online Book Shop like Flipkart but now I lost my .sln file of this project, it has a database connection so how can I create a new .sln file and run my project?? I tried to make blank .sln file and want to add all files of my project but failed to do that so anyone has a solution share.....
