c# 求逐行解释，附有详尽代码
/// <summary>  
  /// 查询

  /// <param name="p_Sql">sql命令</param>
  /// <param name="p_ParaList">参数集</param>

  public static DataTable GetTable(String p_Sql, SqlParameter[] p_ParaList, CommandType p_Type)
  {
  SqlCommand command = CreateCommand(p_Sql, p_ParaList, p_Type);//创建Command对象
  Debug.Assert(null != command);
  SqlConnection conn = new SqlConnection(strConn);
  command.Connection = conn;
  SqlDataAdapter adapter = new SqlDataAdapter(command);//创建数据适配器对象
  DataTable table = new DataTable();//数据容器
  adapter.Fill(table);
  return table;
  }
求逐行解释，望高手解答！

[解决办法]

C# code

        public static DataTable GetTable(String p_Sql, SqlParameter[] p_ParaList, CommandType p_Type)        {            SqlCommand command = CreateCommand(p_Sql, p_ParaList, p_Type);//创建Command对象            Debug.Assert(null != command);            //只要语句不是空值            SqlConnection conn = new SqlConnection(strConn);//创建连接            command.Connection = conn;//设置连接            SqlDataAdapter adapter = new SqlDataAdapter(command);//这里面是SQL语句            DataTable table = new DataTable();//创建表            adapter.Fill(table);//将查询结果赋给表            return table;//返回        }
