Decimal.ToInt32 Method (Decimal)
.NET Framework (current version)
Converts the value of the specified Decimal to the equivalent 32-bit signed integer.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- d
-
Type:
System.Decimal
The decimal number to convert.
| Exception | Condition |
|---|---|
| OverflowException | d is less than Int32.MinValue or greater than Int32.MaxValue. |
The return value is the integral part of the decimal value; fractional digits are truncated.
You can also convert a Decimal value to a 32-bit integer by using the Explicit(Decimal to Int32) assignment operator. Because the operator performs a narrowing conversion, you must use a casting operator in C# or a conversion function in Visual Basic.
The following example uses the ToInt32 method to convert decimal numbers to Int32 values.
using System; class Example { public static void Main( ) { decimal[] values = { 123m, new decimal(123000, 0, 0, false, 3), 123.999m, 4294967295.999m, 4294967296m, 4294967296m, 2147483647.999m, 2147483648m, -0.999m, -1m, -2147483648.999m, -2147483649m }; foreach (var value in values) { try { int number = Decimal.ToInt32(value); Console.WriteLine("{0} --> {1}", value, number); } catch (OverflowException e) { Console.WriteLine("{0}: {1}", e.GetType().Name, value); } } } } // The example displays the following output: // 123 --> 123 // 123.000 --> 123 // 123.999 --> 123 // OverflowException: 4294967295.999 // OverflowException: 4294967296 // OverflowException: 4294967296 // 2147483647.999 --> 2147483647 // OverflowException: 2147483648 // -0.999 --> 0 // -1 --> -1 // -2147483648.999 --> -2147483648 // OverflowException: -2147483649
