Decimal.ToInt32 Method
.NET Framework 4
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 following code example converts Decimal numbers to Int32 values using the ToInt32 method.
