Exemplos

O exemplo seguinte usa a MaxValue propriedade para impedir que um OverflowException ao converter para um Int32 valor.

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.");
