是否可以将动态程序集保存到磁盘？ [英] Is it possible to save a dynamic assembly to disk?

问题描述

我最近买了Ayende的书籍在Boo建立DSLs （购买，阅读它，真棒）但是我反对实现问题，我想看看生成的代码是什么样的。我通常会使用反射器来查看代码，但在这种情况下，程序集是动态的，只在内存中。有没有办法将动态程序集保存到磁盘，以便我可以反映出来？

编辑/我的答案：

$ b哇，花一点时间回到这个。不幸的是，我从原来的问题中留下了重要的一点。

重要位：我正在使用 Ayende的RhinoDSL库，正如他在书中所推荐的那样。我可以访问我的DslEngine子类中的boo编译器，如下所示：

  public class JobEngine：DslEngine 
 {
 protected override void CustomizeCompiler（Boo.Lang.Compiler.BooCompiler compiler，Boo.Lang.Compiler.CompilerPipeline pipeline，string [] urls）
 {
 pipeline.Insert（1，new ImplicitBaseClassCompilerStep （typeof（JobBase），Prepare，JobLanguage，log4net，Quartz））; 
} 
} 
  

要改变最少，得到我想要的东西添加一行...

  public class JobEngine：DslEngine 
 {
 protected override void CustomizeCompiler Boo.Lang.Compiler.BooCompiler编译器，Boo.Lang.Compiler.CompilerPipeline管道，string [] urls）
 {
 compiler.Parameters.GenerateInMemory = false; //< --- This one。 
 pipeline.Insert（1，new ImplicitBaseClassCompilerStep（typeof（JobBase），Prepare，JobLanguage，log4net，Quartz））; 
} 
} 
  

这导致编译器将程序集输出到〜 \LocalSettings\Temp目录，然后我可以反映它。重要的是要注意，这种改变会导致程序的其余部分中断（RhinoDSL可能不再在内存中找到程序集，因为我将它们输出到磁盘），所以这只能用作调试工具。

解决方案

查找BooCompiler实例化的位置，从 CompileToMemory 到 CompileToFile

I recently bought Ayende's book Building DSLs in Boo (buy it, read it, it's awesome) but I'm coming up against an implementation problem and I want to see what the generated code looks like. I would normally use reflector to look at the code but in this case the assemblies are dynamic and only in memory. Is there a way to save dynamic assemblies to disk so that I can reflect them?

EDIT / My Answer:

Wow, it took awhile to come back to this one. Unfortunately I left an important bit out from the original question.

Important Bit: I'm using Ayende's RhinoDSL library as he recommends in the book. I have access to the boo compiler in my subclass of DslEngine which looks like this:

public class JobEngine : DslEngine
{
    protected override void CustomizeCompiler(Boo.Lang.Compiler.BooCompiler compiler, Boo.Lang.Compiler.CompilerPipeline pipeline, string[] urls)
    {
        pipeline.Insert(1, new ImplicitBaseClassCompilerStep(typeof (JobBase), "Prepare", "JobLanguage", "log4net", "Quartz"));
    }
}

To change the least and get what I wanted I needed to add one line...

public class JobEngine : DslEngine
{
    protected override void CustomizeCompiler(Boo.Lang.Compiler.BooCompiler compiler, Boo.Lang.Compiler.CompilerPipeline pipeline, string[] urls)
    {
        compiler.Parameters.GenerateInMemory = false; // <--- This one.
        pipeline.Insert(1, new ImplicitBaseClassCompilerStep(typeof (JobBase), "Prepare", "JobLanguage", "log4net", "Quartz"));
    }
}

This caused the compiler to output the assembly to my ~\LocalSettings\Temp directory and then I could then reflect it. It's important to note that making that change caused the rest of the program to break (RhinoDSL could no longer find the assemblies in memory because I output them to disk), so this is only useful as a debugging tool.

解决方案

Look up where BooCompiler is instantiated, change the pipeline from CompileToMemory to CompileToFile
