How do I specify the equivalent of volatile in VB.net?

by

There’s no equivalent of C#’s volatile keyword in VB.NET. Instead what’s often recommended is the use of MemoryBarrier. Helper methods could also be written:

Function VolatileRead(Of T)(ByRef Address As T) As T
    VolatileRead = Address
    Threading.Thread.MemoryBarrier()
End Function

Sub VolatileWrite(Of T)(ByRef Address As T, ByVal Value As T)
    Threading.Thread.MemoryBarrier()
    Address = Value
End Sub

Also there’s a useful blog post on this subject.
