How Can I Get Around Scope Problems In A Try/catch?

Answer»

If you try to INSTANTIATE the class inside the try, it'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:
Connection conn = null;
try
{
conn = new Connection();
conn.Open();
}
FINALLY
{
if (conn != null) conn.Close();
}
By setting it to null before the try block, you avoid getting the CS0165 error (Use of possibly unassigned local VARIABLE 'conn').
