自动生成数据库字典(sql2008) 转自飘渺の云海

每次做项目的时候都要做数据字典，这种重复的工作实在很是痛苦，于是广找资料，终于完成了自动生成数据库字典的工作，废话少说，上代码.

当然这些通过PRING出来的代码使用传统的方式是调用不到的，通过查找资料，终于在国外一个XXX网站找到了解决方案。

private static string message = "";
        public static string ExecuteNonQuery(string connextionString, CommandType commandType, string commandText, bool outputMsg)
        {
            if (connextionString == null || connextionString.Length == 0) throw new ArgumentNullException("connectionString");

            // Create & open a SqlConnection, and dispose of it after we are done
            using (SqlConnection connection = new SqlConnection(connextionString))
            {
                message = "";
                connection.Open();
                connection.InfoMessage += delegate(object sender, SqlInfoMessageEventArgs e)
                {
                    message += "\n" + e.Message;
                };

                // Call the overload that takes a connection in place of the connection string
                if (connection == null) throw new ArgumentNullException("connection");

                // Create a command and prepare it for execution
                SqlCommand cmd = new SqlCommand(commandText, connection); ;
                cmd.CommandType = commandType;
                // Finally, execute the command
                int retval = cmd.ExecuteNonQuery();

                // Detach the SqlParameters from the command object, so they can be used again
                cmd.Parameters.Clear();
                connection.Close();
                return message;
            }
        }

调用就不用写了嘛。一切就这么简单，生成的是一份标准的htm代码，可直接放到HTML里面，当然也可以直接从数据库读取出来显示。

//以前都是用工具自动生成,但样式不够完美,有了这个可以自定义样式 ;TODO 自己需要修改一下,能够直接生成一个Excel ,这样方便可以修改某一列,某个题头的样式;
