Analysis of datatable serialization and deserialization instances in C

This article illustrates datatable serialization and deserialization in C# and shares it with you for your reference. The specific methods are as follows:

1. datatable serialization

public string getSendDetailQuery(DateTime timeS, DateTime timeE, string sccount)
{
  try
  {
 SmsOperate so = new SmsOperate();

    // get dt
 DataTable dtt = so.getSendDetailQuery(timeS, timeE, sccount);
 JavaScriptSerializer serializer = new JavaScriptSerializer();    
 string aaa = Serialize(dtt, false);//datatable Cannot be serialized directly. This is a serialization method 
 return "0:" + aaa;
 
  }
  catch (Exception e)
  {
 return "-1" + e.Message;
  }
}

/// <summary> Serialization method 
///  You don't need pagination 
/// </summary>
/// <param name="dt"></param>
/// <param name="flag">false</param>
/// <returns></returns>
public string Serialize(DataTable dt, bool flag)
{
  JavaScriptSerializer serializer = new JavaScriptSerializer();
  List<Dictionary<string, object>> list = new List<Dictionary<string, object>>();
  foreach (DataRow dr in dt.Rows)
  {
 Dictionary<string, object> result = new Dictionary<string, object>();
 foreach (DataColumn dc in dt.Columns)
 {
   result.Add(dc.ColumnName, dr[dc].ToString());
 }
 list.Add(result);
  }
  return serializer.Serialize(list); ;
}

datatable deserialization

public DataTable getSendDetailTest()
{
  DataTable dtb = new DataTable();

  // Get the serialization result aaa
  string aaa = getSendDetailQuery(Convert.ToDateTime("2012-01-01 00:00:00"), Convert.ToDateTime("2012-05-01 23:59:59"), "wangsub1");

  if (aaa.Substring(0, 1) == "0")
  {
 try
 {
   JavaScriptSerializer serializer = new JavaScriptSerializer();
  // var obj = serializer.DeserializeObject(aaa);// deserialization 

 aaa=aaa.substring(2,aaa.length-2);

   ArrayList dic = serializer.Deserialize<ArrayList>(aaa);// deserialization ArrayList type 
  
   if (dic.Count > 0)
   {
 foreach (Dictionary<string, object> drow in dic)
 {
   if (dtb.Columns.Count == 0)
   {
  foreach (string key in drow.Keys)
  {
    dtb.Columns.Add(key, drow[key].GetType());// add dt The column 
  }
   }
   DataRow row = dtb.NewRow();
   foreach (string key in drow.Keys)
   {

  row[key] = drow[key];// Add the column value 
   }
   dtb.Rows.Add(row);// add 1 line 
 }
   }
 }
 catch (Exception e)
 {
   //
 }
  }
  else
  {
 //
  }
  
  return dtb;
}
