简单的信息采集程序示例(小偷程序)

最近正准备做一个信息采集的程序，下面是一个简单的采集程序，提供给初学者入门参考。

aspx页面代码

<asp:TextBox ID="Txt_Url" runat="server" Width="441px"></asp:TextBox><br />
<asp:Button id="Btn_GetUrlSource" runat="server" Text="取得网页代码" OnClick="Btn_GetUrlSource_Click"></asp:Button>
<br />
<asp:TextBox id="Txt_UrlSource" runat="server" Width="100%" Height="195px" TextMode="MultiLine"></asp:TextBox><br />
<br />
采集开始代码
<asp:TextBox ID="Txt_First" runat="server" Height="90px" TextMode="MultiLine" Width="280px"></asp:TextBox><br />
<asp:Button ID="Btn_ListCheck" runat="server" OnClick="Btn_ListCheck_Click" Text="测试唯一性" /><br />
采集结束代码
<asp:TextBox ID="Txt_Last" runat="server" Height="90px" TextMode="MultiLine"
Width="280px"></asp:TextBox><br />
<br />
<asp:Button ID="Btn_Result" runat="server" Text="取得采集结果" OnClick="Btn_Result_Click" /><br />
<asp:TextBox ID="Txt_Result" runat="server" Height="134px" TextMode="MultiLine" Width="579px"></asp:TextBox>
