Namespace:   System
Assembly:  mscorlib (in mscorlib.dll)
Syntax
Public Const MaxValue As [%$TOPIC/92chhbf3_en-us_VS_110_2_0_0_0_0%]
public const [%$TOPIC/92chhbf3_en-us_VS_110_2_0_1_0_0%] MaxValue
public:
literal [%$TOPIC/92chhbf3_en-us_VS_110_2_0_2_0_0%] MaxValue
static val mutable MaxValue: [%$TOPIC/92chhbf3_en-us_VS_110_2_0_3_0_0%]
Remarks

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

Examples

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
