Which is more efficient

[andegre]

I am reading some settings from a config file that would be setup by different developers. They can choose to add different settings and leave out other ones. In by abstract classes constructor, I want to read those settings, but I don't want to fail if they don't exist. So my question is, which is more efficient: using a try with an empty catch block, or using a try with an empty finally block? Again, I don't want to do anything if there's an exception.

Example:

            try
            {
                writeDebugLog = ConfigSectionHandler.ReadSetting(AppSection, SettingKeyWriteDebugLog, false);
            }
            catch { }

Or

            try
            {
                writeDebugLog = ConfigSectionHandler.ReadSetting(AppSection, SettingKeyWriteDebugLog, false);
            }
            finally { }
