asp.net 2.0 学习点滴推荐(001)

例如：
<%@ Page Language="C#" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
const int _itemcount = 10;
string GetDisplayItem(int n)
{
return "Item #" + n.ToString();
}
</script>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Simple page</title>
</head>
<body>
<h1>Test Asp.NET 2.0 Page</h1>
<ul>
<% for (int i = 0; i < _itemcount; i++)
{ %>
<li>
<%=GetDisplayItem(i)%>
</li>
<%} %>
</ul>
<% Response.Write("<h2>Total number of items = " + _itemcount.ToString() + "</h2>"); %>
</body>
</html>
该页面生成的类代码为
public class simplepage_aspx : Page, IRequiresSessionState, IHttpHandler
{
// Fields
private static object __fileDependencies;
private static bool __initialized;
private const int _itemcount = 10;
// Methods
[DebuggerNonUserCode]
public simplepage_aspx()
{
base.AppRelativeVirtualPath = "~/SimplePage.aspx";
if (!__initialized)
{
string[] virtualFileDependencies = new string[] { "~/SimplePage.aspx" };
__fileDependencies = base.GetWrappedFileDependencies(virtualFileDependencies);
__initialized = true;
}
}
[DebuggerNonUserCode]
private HtmlHead __BuildControl__control2()
{
HtmlHead head = new HtmlHead("head");
HtmlTitle title = this.__BuildControl__control3();
IParserAccessor accessor = head;
accessor.AddParsedSubObject(title);
return head;
}
[DebuggerNonUserCode]
private HtmlTitle __BuildControl__control3()
{
HtmlTitle title = new HtmlTitle();
IParserAccessor accessor = title;
accessor.AddParsedSubObject(new LiteralControl("Simple page"));
return title;
}
[DebuggerNonUserCode]
private void __BuildControlTree(simplepage_aspx __ctrl)
{
this.InitializeCulture();
HtmlHead head = this.__BuildControl__control2();
IParserAccessor accessor = __ctrl;
accessor.AddParsedSubObject(head);
__ctrl.SetRenderMethodDelegate(new RenderMethod(this.__Render__control1));
}
private void __Render__control1(HtmlTextWriter __w, Control parameterContainer)
{
__w.Write("\r\n\r\n<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd/%22%3E/r/n/r/n");
__w.Write("\r\n\r\n<html xmlns=\"http://www.w3.org/1999/xhtml/%22%3E/r/n");
parameterContainer.Controls[0].RenderControl(__w);
__w.Write("\r\n<body>\r\n <h1>Test Asp.NET 2.0 Page</h1>\r\n <ul>\r\n ");
for (int i = 0; i < 10; i++)
{
__w.Write("\r\n <li>\r\n ");
__w.Write(this.GetDisplayItem(i));
__w.Write("\r\n </li>\r\n ");
}
__w.Write(" \r\n </ul>\r\n ");
int num2 = 10;
base.Response.Write("<h2>Total number of items = " + num2.ToString() + "</h2>");
__w.Write(base.GetType().Assembly.Location);
__w.Write("\r\n</body>\r\n</html>\r\n");
}

在页面任何位置增加 <% =GetType().Assembly.Location %> 来查看生成的代码文件位置以及名称
