请教一个VB.NET常量的有关问题

请问一个VB.NET常量的问题？
阅读VB.NET的代码，有下面几条语句，我想把转换成C#，但不知道&HCF、&HCD、&H14F是什么整数，哪位能告诉我，谢谢！
  Private   Const   EM_SETREADONLY   As   Int32   =   &HCF
  Private   Const   EM_EMPTYUNDOBUFFER   As   Int32   =   &HCD
  Private   Const   CB_SHOWDROPDOWN   As   Int32   =   &H14F

------解决方案--------------------
private const Int32 EM_SETREADONLY = 0xHCF
private const Int32 EM_EMPTYUNDOBUFFER = 0xHCD
private const Int32 CB_SHOWDROPDOWN = 0xH14F
------解决方案--------------------
那是16进制数,可以用计算器来转为十进制;
也可以,
Private Const EM_SETREADONLY As Int32 = &HCF
Private Const EM_EMPTYUNDOBUFFER As Int32 = &HCD
Private Const CB_SHOWDROPDOWN As Int32 = &H14F
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Console.WriteLine(EM_SETREADONLY) '207
Console.WriteLine(EM_EMPTYUNDOBUFFER) '205
Console.WriteLine(CB_SHOWDROPDOWN) '335
End Sub
