如下代码在C#中用到了指针:

unsafe   public   static   PhoneAddress   GetPhoneNumber()
                {
                        PhoneAddress   phoneaddr   =   new   PhoneAddress();

                        Byte[]   buffer   =   new   Byte[516];
                        fixed   (byte*   pAddr   =   buffer)                         {
                                IntPtr   res   =   SmsGetPhoneNumber((IntPtr)pAddr);
                                if   (res   !=   IntPtr.Zero)
                                        throw   new   Exception("Could   not   get   phone   number   from   SIM");

                                byte*   pCurrent   =   pAddr;
                                phoneaddr.AddressType   =   (AddressType)Marshal.ReadInt32((IntPtr)pCurrent);
                                pCurrent   +=   Marshal.SizeOf(phoneaddr.AddressType);
                                phoneaddr.Address   =   Marshal.PtrToStringUni((IntPtr)pCurrent);
                        }

                        return   phoneaddr;
                }

在工具-选项中设置允许unsafe代码
