How can I get around scope problems in a try/catch?

Question:How can I get around scope problems in a try/catch??

Answer: </P><P align=justify>If you try to instantiate the class inside the try, it&#39;ll be out of scope when you try to access it from the catch block. A way to get around this is to do the following: </P><P align=justify>Connection conn = null; </P><P align=justify>try </P><P align=justify>{</P><P align=justify>conn = new Connection();</P><P align=justify>conn.Open();</P><P align=justify>}</P><P align=justify>finally</P><P align=justify>{ </P><P align=justify>if (conn != null) conn.Close(); </P><P align=justify>}</P><P align=justify></P><P align=justify>By setting it to null before the try block, you avoid getting the CS0165 error (Use of possibly unassigned local variable &#39;conn&#39;).
