catch (System.Exception ex)
The ex name is optional. The error just now is because the E is already defined as E.

The error starts at index 42 and the format of the initialization string does not conform to the specification

What's the problem? The code above ..

lisongfox

string strConnectionString = "Data Source = .; initial catalog = database; uid = sa; pwd = xxx";
Write it like this
string strConnectionString = "server = .; uid = sa; pwd =; database = Database"
