Int32.MinValue Field

Represents the smallest possible value of Int32. This field is constant.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public const int MinValue

The value of this constant is -2,147,483,648; that is, hexadecimal 0x80000000.

The following example uses the MinValue 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 {0} to an Int32.", 
                              newNumber);
         }
         else
         {
            Console.WriteLine("Unable to convert {0} to an Int32.", number);
         }
      }
   }
}
// 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.
