Decimal Explicit Conversion (Decimal to Int32)
Defines an explicit conversion of a Decimal to a 32-bit signed integer.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
- Type: System.Decimal
The value to convert.
| Exception | Condition |
|---|---|
| OverflowException | value is less than Int32.MinValue or greater than Int32.MaxValue. |
This operator supports the explicit conversion of a Decimal to a Int32. The syntax for such explicit conversions is language-dependent, and individual language compilers can provide different implementations and return different results. The example illustrates the different return values when you explicitly convert a Decimal value to an Int32 value by using C# and Visual Basic. To perform a conversion that is independent of language, you can call the ToInt32 or the Convert.ToInt32(Decimal) method.
The following example converts Decimal numbers to Int32 values by using the explicit Decimal to Int32 conversion.
// Example of the explicit conversions from decimal to int and // decimal to uint. using System; class DecimalToU_Int32Demo { const string formatter = "{0,17}{1,19}{2,19}"; // Get the exception type name; remove the namespace prefix. public static string GetExceptionType( Exception ex ) { string exceptionType = ex.GetType( ).ToString( ); return exceptionType.Substring( exceptionType.LastIndexOf( '.' ) + 1 ); } // Convert the decimal argument; catch exceptions that are thrown. public static void DecimalToU_Int32( decimal argument ) { object Int32Value; object UInt32Value; // Convert the argument to an int value. try { Int32Value = (int)argument; } catch( Exception ex ) { Int32Value = GetExceptionType( ex ); } // Convert the argument to a uint value. try { UInt32Value = (uint)argument; } catch( Exception ex ) { UInt32Value = GetExceptionType( ex ); } Console.WriteLine( formatter, argument, Int32Value, UInt32Value ); } public static void Main( ) { Console.WriteLine( "This example of the explicit conversions from decimal " + "to int \nand decimal to uint generates the following " + "output.
