Return Value
Type: System.Int32value, rounded to the nearest 32-bit signed integer. If value is halfway between two whole numbers, the even number is returned; that is, 4.5 is converted to 4, and 5.5 is converted to 6.
| Exception | Condition |

| OverflowException | value is greater than Int32.MaxValue or less than Int32.MinValue. |
The following example attempts to convert each element in an array of Decimal values to an integer.
decimal[] values= { Decimal.MinValue, -1034.23m, -12m, 0m, 147m, 199.55m, 9214.16m, Decimal.MaxValue }; int result; foreach (decimal value in values) { try { result = Convert.ToInt32(value); Console.WriteLine("Converted the {0} value '{1}' to the {2} value {3}.", value.GetType().Name, value, result.GetType().Name, result); } catch (OverflowException) { Console.WriteLine("{0} is outside the range of the Int32 type.", value); } } // The example displays the following output: // -79228162514264337593543950335 is outside the range of the Int32 type. // Converted the Decimal value '-1034.23' to the Int32 value -1034. // Converted the Decimal value '-12' to the Int32 value -12. // Converted the Decimal value '0' to the Int32 value 0. // Converted the Decimal value '147' to the Int32 value 147. // Converted the Decimal value '199.55' to the Int32 value 200. // Converted the Decimal value '9214.16' to the Int32 value 9214. // 79228162514264337593543950335 is outside the range of the Int32 type.
