?????}
?
该类封装了一维表数据，其每个列表项具有name、value、type三个属性。该类型的对象数据可以与DataTable的一行进行相互转换，在Web Service中作为复杂数据类型的参数传出。

TSvrException类

?????????/**////?<summary>

?????????/**////?<summary>

?????????public?void?setEData(DataTable?dt)...{}
?
?????????/**////?<summary>
?????????///?异常信息
?????????///?</summary>
?????????public?string?rmsg?...{get;}
?
?????????/**////?<summary>
?????????///?出现异常后可以返回数据
?????????///?</summary>
?????????public?DataTable?rdata?...{get;}
?????}
?
该类继承自System.Exception类，用于封装自定义的异常信息。构造对象时可以传入异常代码和异常信息，也可以使用Des格式的异常信息。Des格式信息格式为“异常编码|异常信息”，例如“20|未找到数据”。
参数标准
接口参数对于int、bool、string等基本数据类型采用直接传入，而对于数据表及列表等数据则需要封装成统一的格式，本标准使用了TStrList的XML格式作为复杂数据参数的传输格式，其说明如下：
§???????? 该字符串使用标准XML格式
§???????? 该字符串是服务端TStrList的XML形式
§???????? 可表示一条记录
示例为：
详细说明如下：
<?
xml?version="1.0"?encoding="UTF-8"
?>
<
row?
title
=""
>
????
<
column?
name
="Column1"
?type
="number"
>
数据1
</
column
>
????
<
column?
name
="Column2"
?type
="string"
>
数据2
</
column
>
</
row
>
?
§???????? <row>为根节点，表示此行，<row>的子节点<column>表示本行的一列，包括name和type两个属性，分别表示列名和类型
