信息管理实验5-ASP.NET操作XML

1:实验目的,实验要求(自己写) 2:实验步骤: 一:Xml是实现病历共享的另外一种较好的方式。C#通过System.Xml空间下的一系列类来处理XML文档,如何使用这些类呢? 在应用程序的头部添加: using System.Xml 二:新建patient.xml文档

<?xml version="1.0" encoding="gb2312"?>
<patientsmaterial>
</patientsmaterial>

三:创建ASP.NET应用程序,并在窗体上添加两个BUTTON按钮,5个TextBox,如图:

给出代码:
Default.aspx

 <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="输出所有节点(Button1)" />
<asp:Button ID="Button2" runat="server" OnClick="Button2_Click" Text="添加一个节点(Button2)" /></div>
</form>
