Format exception when I am converting to Int32

Question

While i am trying to convert a value to Int32, I get an error format exception, meaning the value is not in the proper format. I think I am converting a value in right forma

Answer 1

You will get FormatException in cases such next:

Convert.ToInt32("foo");
Convert.ToInt32(5.5);

because

FormatException

value does not consist of an optional sign followed by a sequence of digits (0 through 9).
