默认情况下，自定义控件的标记之间的任何内容都被添加为子控件。这可以在AddParsedSubObject()覆盖中截获，用于过滤或额外的解析(例如，LiteralControls中的文本内容):

    protected override void AddParsedSubObject(object obj)
     { var literal = obj as LiteralControl;
       if (literal != null) Controls.Add(parseControl(literal.Text));
       else base.AddParsedSubObject(obj);
     }

...

   <uc:MyControl runat='server'>
     ...this text is parsed as a LiteralControl...
  </uc:MyControl>

默认情况下，任何web表单页面都继承自System.Web.UI.Page类。如果您希望您的页面继承自自定义基类，继承自System.Web.UI.Page怎么办?

有一种方法可以约束任何页面从您自己的基类继承。只需在web.config中添加一行:

<system.web>
    <pages pageBaseType="MyBasePageClass" />
</system.web>

注意:只有当你的类是一个独立的类时，这才有效。我的意思是一个没有隐藏代码的类，它看起来像<%@ Page Language=" c# " AutoEventWireup="true" %>

零售模式在机器。配置水平:

<configuration>
  <system.web>
    <deployment retail="true"/>
  </system.web>
</configuration>

覆盖网络。配置设置以强制调试为false，打开自定义错误并禁用跟踪。不再忘记在发布之前更改属性—只需将它们全部配置为开发或测试环境，并更新生产零售设置。

你知道可以用ASP。IIS或Visual Studio之外的网络?

整个运行时都打包好了，可以在任何想要尝试的进程中托管。使用ApplicationHost, HttpRuntime和HttpApplication类，你也可以打磨这些.aspx页面，并从中得到漂亮的HTML输出。

HostingClass host = ApplicationHost.CreateApplicationHost(typeof(HostingClass), 
                                            "/virtualpath", "physicalPath");
host.ProcessPage(urlToAspxFile); 

你的主持课程:

public class HostingClass : MarshalByRefObject
{
    public void ProcessPage(string url)
    {
        using (StreamWriter sw = new StreamWriter("C:\temp.html"))
        {
            SimpleWorkerRequest worker = new SimpleWorkerRequest(url, null, sw);
            HttpRuntime.ProcessRequest(worker);
        }
                    // Ta-dah!  C:\temp.html has some html for you.
    }
}

HttpContext.Current will always give you access to the current context's Request/Response/etc., even when you don't have access to the Page's properties (e.g., from a loosely-coupled helper class). You can continue executing code on the same page after redirecting the user to another one by calling Response.Redirect(url, false ) You don't need .ASPX files if all you want is a compiled Page (or any IHttpHandler). Just set the path and HTTP methods to point to the class in the <httpHandlers> element in the web.config file. A Page object can be retrieved from an .ASPX file programmatically by calling PageParser.GetCompiledPageInstance(virtualPath,aspxFileName,Context)

代码表达式构建器

样本的标记:

Text = '<%$ Code: GetText() %>'
Text = '<%$ Code: MyStaticClass.MyStaticProperty %>'
Text = '<%$ Code: DateTime.Now.ToShortDateString() %>'
MaxLenth = '<%$ Code: 30 + 40 %>'

代码表达式构建器的真正美妙之处在于，您可以像在非数据绑定情况下使用表达式一样使用数据绑定。您还可以创建执行其他功能的其他表达式生成器。

. config:

<system.web>    
    <compilation debug="true">
        <expressionBuilders>
            <add expressionPrefix="Code" type="CodeExpressionBuilder" />

实现这一切的cs类:

[ExpressionPrefix("Code")]
public class CodeExpressionBuilder : ExpressionBuilder
{
    public override CodeExpression GetCodeExpression(
        BoundPropertyEntry entry,
        object parsedData,
        ExpressionBuilderContext context)
    {            
        return new CodeSnippetExpression(entry.Expression);
    }
}
