HttpRuntime应用程序运行时

System.Web.HttpRuntime类是整个Asp.net服务器处理的入口。

这个类提供了一系列的静态属性，反映web应用程序域的设置信息，而且每个web应用程序域中存在一个System.Web.Runtime类。

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 using System.Web;
 6 using System.Web.UI;
 7 using System.Web.UI.WebControls;
 8
 9 namespace HttpRuntimeDemo
10 {
11     public partial class _default : System.Web.UI.Page
12     {
13         protected void Page_Load(object sender, EventArgs e)
14         {
15             StringBuilder sb = new StringBuilder();
16             //应用程序域id
17             sb.AppendFormat("AppDomainAppId:{0}<br/>", HttpRuntime.AppDomainAppId);
18             //web应用程序所在文件目录
19             sb.AppendFormat("AppDomainAppPath:{0}<br/>", HttpRuntime.AppDomainAppPath);
20             //web应用程序的虚拟目录
21             sb.AppendFormat("AppDomainAppVirtualPath:{0}<br/>", HttpRuntime.AppDomainAppVirtualPath);
22             //客户端脚本在服务器上的文件目录
23             sb.AppendFormat("AspClientScriptPhysicalPath:{0}<br/>", HttpRuntime.AspClientScriptPhysicalPath);
24             //客户端脚本在服务器上的虚拟目录
25             sb.AppendFormat("AspClientScriptPhysicalPath:{0}<br/>", HttpRuntime.AspClientScriptVirtualPath);
26             //asp.net安装目录
27             sb.AppendFormat("AspInstallDirectory:{0}<br/>", HttpRuntime.AspInstallDirectory);
28             //bin目录
29             sb.AppendFormat("BinDirectory:{0}<br/>", HttpRuntime.BinDirectory);
30             //clr安装目录
31             sb.AppendFormat("ClrInstallDirectory:{0}<br/>", HttpRuntime.ClrInstallDirectory);
32             //生成代码的目录
33             sb.AppendFormat("CodegenDir:{0}<br/>", HttpRuntime.CodegenDir);
34             //iss版本
35             sb.AppendFormat("IISVersion:{0}<br/>", HttpRuntime.IISVersion.MajorRevision.ToString());
36             //本机配置文件所在的目录
37             sb.AppendFormat("MachineConfigurationDirectory:{0}<br/>", HttpRuntime.MachineConfigurationDirectory);
38             //是否使用iis7集成模式
39             sb.AppendFormat("UsingIntegratedPipeline:{0}<br/>", HttpRuntime.UsingIntegratedPipeline.ToString());
40             // Summary:
41             //     Gets a value that indicates whether the application is mapped to a universal
42             //     naming convention (UNC) share.
43             sb.AppendFormat("IsOnUNCShare:{0}<br/>", HttpRuntime.IsOnUNCShare.ToString());
44             Response.Write(sb.ToString());
45
46         }
47     }
48 }

上面列出了HttpRuntime主要的几个静态属性，输出结果为：

而HttpRuntime的静态方法ProcessRequest将帮助我们处理Http请求。

 1 //
 2         // Summary:
 3         //     Drives all ASP.NET Web processing execution.
 4         //
 5         // Parameters:
 6         //   wr:
 7         //     An System.Web.HttpWorkerRequest for the current application.
 8         //
 9         // Exceptions:
10         //   System.ArgumentNullException:
11         //     The wr parameter is null.
12         //
13         //   System.PlatformNotSupportedException:
14         //     The Web application is running under IIS 7 in Integrated mode.
15         public static void ProcessRequest(HttpWorkerRequest wr);
