vs2005 c#.net 2.0:我可以将数据表结果存储在哪里

Question

这仅用于调试目的.我们有一个滥用的存储过程,需要永远返回结果集. 目前优化过程是不可能的.我是否有可能将加载的数据集结果存储在某些地方,所以我不必一遍又一遍地调用存储过程.我可以继续测试我的.net代码.我不想将其缓存在内存中,而是将其存储在本地文件中.

DataSet ds = db.ExecuteDataSet(cmdobject);
//Store this result some where
//so next time I dont have to call the above method. Just pick up the stored result //from some where and continue with my testing. 

任何代码示例都会有帮助.

Answer 1

DataSet.WriteXml()？

Answer 2

Well DataSet实现了ISerializable接口,因此您可以将其序列化为文件.

例:

  DataSet ds = new DataSet();
  if (File.Exists("SavedDataSet.dat"))
  {
     // If the serialized object exists, read it from the file
     // and deserialize it
     DataSet ds;
     Stream stream = File.Open("SavedDataSet.dat", FileMode.Open);
     BinaryFormatter bFormatter = new BinaryFormatter();
     ds = (DataSet)bFormatter.Deserialize(stream);
     stream.Close();
  }
  else
  {
     // If the serialized object doesn't exist, run the stored 
     // procedure and then serialize the result    
     ds = db.ExecuteDataSet(cmdobject);
     Stream stream = File.Open("SavedDataSet.dat", FileMode.Create);
     BinaryFormatter bFormatter = new BinaryFormatter();
     bFormatter.Serialize(stream, ds);
     stream.Close();
  }
