Represents the largest possible value of an Int32. This field is constant.

Namespace:  System

'Declaration
Public Const MaxValue As Integer

The value of this constant is 2,147,483,647; that is, hexadecimal 0x7FFFFFFF.

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

Module modMain
   Public Sub Main()
      Dim numbersToConvert() As Long = { 162345, 32183, -54000, Int64.MaxValue\2 }
      Dim newNumber As Integer 
      For Each number As Long In NumbersToConvert
         If number >= Int32.MinValue And number <= Int32.MaxValue Then
            newNumber = Convert.ToInt32(number)
            Console.WriteLine("Successfully converted {0} to an Int32.", _
                              newNumber)
         Else
            Console.WriteLine("Unable to convert {0} to an Int32.", number)
         End If                      
      Next 
   End Sub 
End Module
