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

If your code looks like this:

using (SqlCommand cmd = new SqlCommand(...))
{
  try
  {
    /* call stored procedure */
  }
  catch (SqlException ex)
  {
    /* handles the exception. does not rethrow the exception */
  }
}

Then I would refactor it to use try.. catch.. finally instead.

SqlCommand cmd = new SqlCommand(...)
try
{
  /* call stored procedure */
}
catch (SqlException ex)
{
  /* handles the exception and does not ignore it */
}
finally
{
   if (cmd!=null) cmd.Dispose();
}

In this scenario, I would be handling the exception so I have no choice but to add in that try..catch, I might as well put in the finally clause and save myself another nesting level. Note that I must be doing something in the catch block and not just ignoring the exception.
