I converted your code to VB (yes, VB) and it does work. Considering speed, do you think your method is faster:

 

 


    Public Shared Function Build64(ByVal value As Object) As UInt64
        Dim High As Int32 = value.high
        Dim Low As Int32 = value.low
        Dim lowLow As Int32 = value.low And &HFFFF
        Dim lowHigh As Int32 = (value.low >> 16) And &HFFFF
        Dim high64 As UInt64 = Convert.ToUInt64(High)
        Dim lowLow64 As UInt64 = Convert.ToUInt64(lowLow)
        Dim lowHigh64 As UInt64 = Convert.ToUInt64(lowHigh)
        Dim final As UInt64 = (high64 << 32) Or (lowHigh64 << 16) Or lowLow64
        Return myfinal
    End Function
