Setting iEditMode = 0 inside the curly braces is not a good example. Better to do something else inside the braces such as output something or disable buttons or whatever is needed.

But when TryParse returns, the out parameter is zero if the conversion failed. So if you want iEditMode = 0 when the conversion fails you may just write Int32.TryParse(strEditMode, out iEditMode) with no check on the return value. The example is confusing, because it may let us believe that the out-parameter is unchanged when conversion fails.

But when TryParse returns, the out parameter is zero if the conversion failed.

So if you want iEditMode = 0 when the conversion fails you may just write
Int32.TryParse(strEditMode, out iEditMode)
with no check on the return value.
