Error 3 'System.Data.SqlClient.SqlCommand' does not contain a definition for 'close' and no extension method 'close' accepting a first argument of type 'System.Data.SqlClient.SqlCommand' could be found (are you missing a using directive or an assembly reference?)

I am failling to understand what this means

Solution 1

The error message is telling you exactly what the problem is

C#

con.Close()

should be

C#

con.Close();

And use parameterized queries to prevent SQL injection attacks.

To answer your completely new and unrelated question, C# is a case sensitive language. Close() and close() are unrelated function calls. A SqlCommand object does not have a Close method which is what the error is telling you. You should be wrapping objects that implement IDisposable in using statements anyway.
