c++的位域该如何转换到C#中?

用enum+FlagsAttribute来做[Flags]
public enum ComStatFlags {
    fCtsHold = 0x1, fDsrHold = 0x2, fRlsdHold = 0x4,
    fXoffHold = 0x8, fXoffSent = 0x10, fEof = 0x20,
    fTxim = 0x40
} public strut COMSTAT {
    public ComStatFlags flags;
    public uint cbInQue;
    public uint cbOutQue;
    ...
}
