How to create a transaction in asp.net

1. Create a List to store multiple statements

/// 

/// 保存表单
/// 
/// 
protected void save()
{
 List list = new List();
 list.Add(string.Format("insert into picsone(model,idser,idflg,lmuser,lmdate,lmtime) values('{0}','{1}','{2}','{3}',{4},{5})", "T1002", "Y", "N", "U001", 20161103, 140025));
 list.Add(string.Format("insert into picstwo(model,idser,idflg,lmuser,lmdate,lmtime) values('{0}','{1}','{2}','{3}',{4},{5})", "T1002", "Y", "N", "U001", 20161103, 140025));
 bool bol = ExecuteTransaction(list);
 if (bol)
 {
  MessageBox.Show("保存成功！");
 }
 else
 {
  MessageBox.Show("保存失败！");
 }
}

2. Call the ExecuteTransaction method and return the return value true for success, false for failure, and the statement will be rolled back

/// 

/// 执行语句
/// 
/// 
/// 
private bool ExecuteTransaction(List list)
{
 using (SqlConnection connection = new SqlConnection(ConfigurationManager.AppSettings["LocalConnectionString"].ToString()))
 {
  SqlCommand command = new SqlCommand();
  SqlTransaction transaction = null;
  try
  {
   connection.Open();
   transaction = connection.BeginTransaction();
   command.Connection = connection;
   command.Transaction = transaction;
  
   for (int i = 0; i < list.Count; i++)
   {
    command.CommandText = list[i];
    command.ExecuteNonQuery();
   }
  
   transaction.Commit();
   connection.Close();
   return true;
  }
  catch
  {
   transaction.Rollback();
   connection.Close();
   return false;
  }
 }
}
