Question

C#读取缓冲区数据

怎么读取？

Answer 1

private void MyRealDataCallBack(int lRealHandle, uint
dwDataType, [MarshalAs(UnmanagedType.LPArray)] byte[] pBuffer, uint
dwBufSize, uint dwUser)

这个方法中的参数[MarshalAs(UnmanagedType.LPArray)] byte[] pBuffer,返回的是缓冲区的指针.

追问

具体怎么用啊 有例子最好

Answer 2

object blackCache = HttpContext.Current.Cache.Get("BlackCache");
List<string> blackList = null;
if (blackCache == null)
{
DisableIPTable dit = new DisableIPTable();
blackList = dit.GetBlackIp();
ServiceCache.Set("BlackCache", blackList);
}
else
{
blackList = (List<string>)blackCache;
}

return blackList;
