Public Shared Function ToUInt64 (
	value As Byte
) As ULong

Parameters

value
Type: System.Byte

The 8-bit unsigned integer to convert.

Return Value

Type: System.UInt64

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

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

Dim bytes() As Byte = { Byte.MinValue, 14, 122, Byte.MaxValue}
Dim result As ULong

For Each byteValue As Byte In bytes
   result = Convert.ToUInt64(byteValue)
   Console.WriteLine("Converted the {0} value {1} to the {2} value {3}.", _
                     byteValue.GetType().Name, byteValue, _
                     result.GetType().Name, result)
Next
' The example displays the following output:
'    Converted the Byte value 0 to the UInt64 value 0.
'    Converted the Byte value 14 to the UInt64 value 14.
'    Converted the Byte value 122 to the UInt64 value 122.
'    Converted the Byte value 255 to the UInt64 value 255.
