Question

I saw the following namespace implementation in an article and i really can’t get the point why they did so?

using sysConfig =System.Configuration ;

string connectionString = sysConfig.ConfigurationManager.
                         ConnectionStrings["connectionString"].ConnectionString;

I know It can be easily implemented like this,

string connectionString = System.Configuration.ConfigurationManager.
                         ConnectionStrings["connectionString"].ConnectionString;

Any suggestion when to use the first type…

Two reasons for using namespace aliases:

1. To resolve conflicts between namespaces
2. To make code more readable (shorter namespace names)

In the example you provided, I don’t see the benefit though. It just confuses the person reading the code.
