How tryParse method works in C#?

Question

By-default all the methods & variables in class are private.

In C#.net Main() method is private then how compiler access this Main() Method out side the class because compiler is not part of our program then how compiler access this Main() method?

Here we loose our data abstraction property ? Can anyone put some light on it?

Answer 1

The int.TryParse method converts strings into ints. It never throws an exception—even on invalid input and null. It is called in a different way than int.Parse. It is overall preferable to int.Parse in most program contexts.
TryParse
Note:Use int.TryParse to parse integers in most situations. This is often faster and results in simpler logic.
Note 2:This method is ideal for input that is not always correct. When errors occur, performance is better.

int quantity;
try
{
    quantity = int.Parse(txtQuantity.Text);
}
catch (FormatException)
{
    quantity = 0;
}
catch (OverflowException)
{
    quantity = 0;
}
