C# Code:

static void Main(string[] args)
{
   
   string xml = @"E:\XQ-ERP\测试数据\nwind.xml";
   FileStream fs = File.OpenRead(xml);
   long a = fs.Length;//原始数据大小
   fs.Close();
   
   DataSet ds = new DataSet();
   ds.ReadXml(xml);
   byte[] bs = ZipTools.CompressionDataSet(ds);//压缩DataSet-->byte[]
   long b = bs.Length;//压缩后大小
   
   Console.WriteLine("未压缩数据的字节数：" a.ToString());
   Console.WriteLine("压缩后数据字节数：" b.ToString());
   Console.WriteLine("压缩后比原数据要少：" (a - b).ToString());
   
   double rate = ((a - b) / (a * 1.00)) * 100;
   rate = Math.Round(rate, 2);
   Console.WriteLine("压缩比例: " rate.ToString() "%");
   
   //测试压缩后的数据能不能还原
   string xml1 = @"E:\XQ-ERP\测试数据\nwind_1.xml";
   DataSet ds1 = ZipTools.DecompressionDataSet(bs);//还原数据
   ds1.WriteXml(xml1, XmlWriteMode.WriteSchema);//一定要写入DataSet表结构元数据
   
   FileStream fs1 = File.OpenRead(xml1);
   long aa = fs1.Length;//原始数据大小
   fs1.Close();
   
   Console.WriteLine("还原后的数据字节数：" aa.ToString());
   Console.ReadLine();
}
