Code snippet
The following code snippet reads an environment variable named DefaultConnection.
public class Program
{
public static void Main()
{
var dbConnString = Environment.GetEnvironmentVariable("DefaultConnection");

}
The value of the variable can be stored in your system level environment variables or in development environment, it can be stored in local.settings.json file.

"AzureWebJobsStorage": "UseDevelopmentStorage=true",
"FUNCTIONS_WORKER_RUNTIME": "dotnet-isolated"
}
}
