C# using statement catch error

Question

I am just looking at the using statement, I have always known what it does but until now not tried using it, I have come up with the below code:

 using (SqlComma         


        

Answer 1

Elaborating on what Chris Ballance said, the C# specification (ECMA-334 version 4) section 15.13 states "A using statement is translated into three parts: acquisition, usage, and disposal. Usage of the resource is implicitly enclosed in a try statement that includes a finally clause. This finally clause disposes of the resource. If a null resource is acquired, then no call to Dispose is made, and no exception is thrown."

The description is close to 2 pages - worth a read.

In my experience, SqlConnection/SqlCommand can generate errors in so many ways that you almost need to handle the exceptions thrown more than handle the expected behaviour. I'm not sure I'd want the using clause here, as I'd want to be able to handle the null resource case myself.
