How to Handle int.Parse Exceptions with Empty or Invalid Input Strings?

int.Parse Exception: Navigating Empty Input Strings

When attempting to parse an empty string using int.Parse(Textbox1.text), you may encounter the error "Input string was not in a correct format" due to the absence of valid numeric content within the string. To address this issue, consider the following approaches:

Defaulting to 0 on Empty Input with Exception on Invalid Format:

If you wish to assign the default value of 0 to an empty textbox while raising an exception for incorrectly formatted input, use the following code:

int i = string.IsNullOrEmpty(Textbox1.Text) ? 0 : int.Parse(Textbox1.Text);

Defaulting to 0 with Any Invalid Input:

Alternatively, if you prefer to default to 0 regardless of poorly formatted input, employ the following:

int i;
if (!int.TryParse(Textbox1.Text, out i)) i = 0;
