Overflow during operation C# with Example
Overflow also happens during the operation. In the following example, x is an int, 1 is an int by default. Therefore addition is an int addition. And the result will be an int. And it will overflow. int x = int.MaxValue; //MaxValue is 2147483647 //It will be overflown long y = x + 1; Console.WriteLine(y); //Will print -2147483648 //Same as Min value Console.WriteLine(int.MinValue); You can prevent that by using 1L. Now 1 will be a long and addition will be a long addition int x = int.MaxValue; //MaxValue is 2147483647 long y = x + 1L; //It will be OK Console.WriteLine(y); //Will print 2147483648
