如果您为 ASPNET 运行时构建主机，则可以在没有 IIS、没有 HTTP 消息的情况下运行 ASPX 页面。
例子：
public class MyAspNetHost : System.MarshalByRefObject
{
public void ProcessRequest(string page)
{
var request = new System.Web.Hosting.SimpleWorkerRequest
(page, // the page being requested
null, // query - none in this case
System.Console.Out // output - any TextWriter will do
);
// this will emit the page output to Console.Out
System.Web.HttpRuntime.ProcessRequest(request);
}
public AppDomain GetAppDomain()
{
return System.Threading.Thread.GetDomain();
}
}
public class Example
{
public void Run(IEnumerable<String> pages)
{
// ASPNET looks for assemblies - including the assembbly
// that contains any custom ASPNET host - in the bin\
// subdirectory of the physical directory that backs the
// ASPNET Host. Because we are going to use the current
// working directory as the physical backing directory for
// the ASPNET host, we need to ensure there's a bin
// subdirectory present.
bool cleanBin = false;
if (!Directory.Exists("bin"))
{
cleanBin = true;
Directory.CreateDirectory("bin");
}
// Now, ensure that the assembly containing the custom host is
// present in that bin directory. The assembly containing the
// custom host is actually *this* assembly.
var a = System.Reflection.Assembly.GetExecutingAssembly();
string destfile= Path.Combine("bin", Path.GetFileName(a.Location));
File.Copy(a.Location, destfile, true);
host =
(MyAspNetHost) System.Web.Hosting.ApplicationHost.CreateApplicationHost
( typeof(MyAspNetHost),
"/foo", // virtual dir - can be anything
System.IO.Directory.GetCurrentDirectory() // physical dir
);
// process each page
foreach (string page in pages)
host.ProcessRequest(page);
}
}
如果你想清理那个 bin 目录，你必须先让 AppDomain 卸载。你可以这样做，像这样：
private ManualResetEvent aspNetHostIsUnloaded;
private void HostedDomainHasBeenUnloaded(object source, System.EventArgs e)
{
// cannot clean bin dir here. The AppDomain is not yet gone.
aspNetHostIsUnloaded.Set();
}
private Run(IEnumerable<String> pages)
{
try
{
....code from above ....
}
finally
{
if (host!= null)
{
aspNetHostIsUnloaded = new ManualResetEvent(false);
host.GetAppDomain().DomainUnload += this.HostedDomainHasBeenUnloaded;
AppDomain.Unload(host.GetAppDomain());
// wait for it to unload
aspNetHostIsUnloaded.WaitOne();
// optionally remove the bin directory
if (cleanBin)
{
Directory.Delete("bin", true);
}
aspNetHostIsUnloaded.Close();
}
}
}
这对于测试 ASPX 页面以及诸如此类的事情是有意义的。但是对于您的情况，我不确定这是否正确。有更直接的方法来生成文本文件。但是，它可能适合你。如果您真的喜欢模板引擎的想法，那么托管 ASPNET 可能正是您的理想之选。
在您的情况下，您可能希望修改自定义主机，以便每个页面的输出转到 StringWriter 而不是 Console.Out，然后您可以执行 Grep（或者更可能使用 Regex 进行搜索) 在该输出上。您可能还想修改它以接受所有输入数据作为查询字符串。您需要格式化页面请求才能做到这一点。
编辑：有a good article on MSDN Magazine on this technique of hosting the ASPNET runtime。从 2004 年 12 月开始。
EDIT2：有一种更简单的方法来管理 bin 目录。只需创建一个名为 bin 的符号链接，指向“.”。然后，您可以在调用 AppDomain.Unload() 后删除符号链接，而无需等待。看起来像这样：
public void Run(string[] pages)
{
bool cleanBin = false;
MyAspNetHost host = null;
try
{
// This creates a symlink.
// ASPNET always looks for a bin\ directory for the privateBinPath of the AppDomain.
// This will create the bin dir, pointing to the current dir.
if (!Directory.Exists("bin"))
{
cleanBin = true;
CreateSymbolicLink("bin", ".", 1);
}
host =
(MyAspNetHost) System.Web.Hosting.ApplicationHost.CreateApplicationHost
( typeof(MyAspNetHost),
"/foo", // virtual dir - can be anything
System.IO.Directory.GetCurrentDirectory() // physical dir
);
foreach (string page in pages)
host.ProcessRequest(page);
}
finally
{
// tell the host to unload
if (host!= null)
{
AppDomain.Unload(host.GetAppDomain());
if (cleanBin)
{
// remove symlink - can do without waiting for AppDomain unload
Directory.Delete("bin");
}
}
}
}
这消除了 ManualResetEvent、复制文件、同步等的需要。它假定自定义 ASPNet 主机的程序集以及您运行的 ASPX 页面所需的所有程序集都包含在当前工作目录中。
