Int32.MaxValue Field

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

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

'Declaration
Public Const MaxValue As Integer
'Usage
Dim value As Integer 

value = Integer.MaxValue

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

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

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 
' 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.
