自动生成数据库字典(sql2008)
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。
