Public Shared Function ToInt64 (
	value As UInteger
) As Long


Type: System.UInt32

The 32-bit unsigned integer to convert.

Return Value

Type: System.Int64

A 64-bit signed integer that is equivalent to value.

The following example converts each element in an array of unsigned integers to a long integer.

Dim numbers() As UInteger = { UInt32.MinValue, 121, 340, UInt32.MaxValue }
Dim result As Long
For Each number As UInteger In numbers
   result = Convert.ToInt64(number)
   Console.WriteLine("Converted the {0} value {1:N0} to the {2} value {3:N0}.", _
                     number.GetType().Name, number, _
                     result.GetType().Name, result)
' The example displays the following output:
'    Converted the UInt32 value 0 to the Int64 value 0.
'    Converted the UInt32 value 121 to the Int64 value 121.
'    Converted the UInt32 value 340 to the Int64 value 340.
'    Converted the UInt32 value 4,294,967,295 to the Int64 value 4,294,967,295.
