Converts the value of the specified 64-bit signed integer to an equivalent 32-bit signed integer.

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

Public Shared Function ToInt32 (
	value As Long
) As Integer

Parameters

value
Type: System.Int64

The 64-bit signed integer to convert.

Return Value

Type: System.Int32

A 32-bit signed integer that is equivalent to value.

Exception Condition
OverflowException

value is greater than Int32.MaxValue or less than Int32.MinValue.

The following example attempts to convert each element in an array of long integers to an integer.

Dim numbers() As Long = { Int64.MinValue, -1, 0, 121, 340, Int64.MaxValue }
Dim result As Integer
For Each number As Long In numbers
   Try
      result = Convert.ToInt32(number)
      Console.WriteLine("Converted the {0} value {1} to the {2} value {3}.", _
                        number.GetType().Name, number, _
                        result.GetType().Name, result)
   Catch e As OverflowException
      Console.WriteLine("The {0} value {1} is outside the range of the Int32 type.", _
                        number.GetType().Name, number)
   End Try
Next
' The example displays the following output:
'    The Int64 value -9223372036854775808 is outside the range of the Int32 type.
'    Converted the Int64 value -1 to the Int32 value -1.
'    Converted the Int64 value 0 to the Int32 value 0.
'    Converted the Int64 value 121 to the Int32 value 121.
'    Converted the Int64 value 340 to the Int32 value 340.
'    The Int64 value 9223372036854775807 is outside the range of the Int32 type.
