从第13个字节开始就是分红数据，股票代码为8个字节，其后8个字节留空，后面是历次的分红日期及分红方式，最后以"FF FF FF FF"结束，如该股票没有分红记录则其记录长度为最小的20字节。一条分红记录占20个字节，依次是
日期 4Byte，32位整数，距1970-01-01的秒数
送股+转增股 4Byte，Single，每股送股数加每股转增股数，具体的方式此文件中没有记录
配股 4Byte，Single，每股配股数
配股价 4Byte，Single，每股配股价
分红 4Byte，Single，每股分红
以下是提取数据的原代码：
BinaryReader sReader = new BinaryReader(File.Open(@"D:\Program Files\dzh2\Download\PWR\full.PWR", FileMode.Open));
sReader.BaseStream.Position = 12;
int k;
while(sReader.BaseStream.Length>sReader.BaseStream.Position)
{
Console.WriteLine(System.Text.Encoding.Default.GetString(sReader.ReadBytes(8)));
sReader.BaseStream.Position += 8;
k = sReader.ReadInt32();
while (k > 0)
{
Console.WriteLine(DateTime.Parse("1970-01-01").AddSeconds(k));
Console.WriteLine(sReader.ReadSingle());
Console.WriteLine(sReader.ReadSingle());
Console.WriteLine(sReader.ReadSingle());
Console.WriteLine(sReader.ReadSingle());
if (sReader.BaseStream.Length > sReader.BaseStream.Position)
k = sReader.ReadInt32();
else
break;
}
}
sReader.Close();
