catching and ignoring an exception

if you want to catch an exception and ignore it, do this to avoid the compiler warning:

catch
{
//do nothing
}

instead of:

catch (Exception ex)
{
//do nothing
}

you can similarly catch exceptions of a certain type without assigning a variable to them, for example:

catch (ArgumentException)
{
//do nothing
}

instead of:

catch (ArgumentException ex)
{
//do nothing
}
