Field Value

Examples

The following example uses the MaxValue property to prevent an OverflowException when converting to an Int32 value.

using System;

public class Class1
{
 public static void Main()
 {
 long[] numbersToConvert = { 162345, 32183, -54000, Int64.MaxValue/2 };
 int newNumber;
 foreach (long number in numbersToConvert)
 {
 if (number >= Int32.MinValue && number <= Int32.MaxValue)
 {
 newNumber = Convert.ToInt32(number);
 Console.WriteLine($"Successfully converted {newNumber} to an Int32.");
 }
 else
 {
 Console.WriteLine($"Unable to convert {number} to an Int32.");
 }
 }
 }
}
// The example displays the following output to the console:
// Successfully converted 162345 to an Int32.
// Successfully converted 32183 to an Int32.
// Successfully converted -54000 to an Int32.
// Unable to convert 4611686018427387903 to an Int32.

open System

let numbersToConvert = [ 162345L; 32183L; -54000L; Int64.MaxValue / 2L ]
for number in numbersToConvert do
 if number >= Int32.MinValue && number <= Int32.MaxValue then
 let newNumber = Convert.ToInt32 number
 printfn $"Successfully converted {newNumber} to an Int32."
 else
 printfn $"Unable to convert {number} to an Int32."
 

// The example displays the following output to the console:
// Successfully converted 162345 to an Int32.
// Successfully converted 32183 to an Int32.
// Successfully converted -54000 to an Int32.
