Hello all,

My application is in VB.net and I am having one clsdatabase class.
In that i am having source code like below for connection string.

con = New SqlConnection(System.Configuration.ConfigurationManager.AppSettings("strConString1"));

but the same thing i want to implement in C#...

I just converted that in to

con = new SqlConnection(System.Configuration.ConfigurationManager.AppSettings("strConString1"))

but it will blow error while execution.

Non-Invocable member.

System.Configuration.ConfigurationManager.AppSettings cannot be used like a method...

So how can i tackle that?

Change the brackets!

con = new SqlConnection(System.Configuration.ConfigurationManager.AppSettings("strConString1"))

Becomes

con = new SqlConnection(System.Configuration.ConfigurationManager.AppSettings["strConString1"])

Hello.

I think the correct way to write this in C# is:

System.Configuration.ConfigurationManager.AppSettings[keyName]

(Square brackets.)
