c# – AssemblyResolve没有为依赖关系触发

我有一个bootstrapper类与静态方法(我将删除我们拥有的线程安全代码,只是为了清楚起见：

public static voID Initialize(){    AppDomain.CurrentDomain.AssemblyResolve += Customresolve;}private static Assembly Customresolve(object sender,ResolveEventArgs args){    // There is a lot code here but basicall what it does.    // Is determining which architecture the computer is running on and    // extract the correct embedded dll (x86 or x64). The code was based    // on milang on GitHub (https://github.com/milang/P4.net). And it's the same    // purpose we want to be able to load the x86 or x64 version of the perforce dll    // but this time with the officially Perforce supported p4API.net.    // Once the dll is extracted we assign it to the boostrapper    bootstrapper._p4dnAssembly = Assembly.Loadfile(targetfilename);    // Make sure we can satisfy the requested reference with the embedded assembly (Now extracted).    Assemblyname reference = new Assemblyname(args.name);    if (Assemblyname.ReferenceMatchesDeFinition(reference,bootstrapper._p4dnAssembly.Getname()))    {        return bootstrapper._p4dnAssembly;    }}

我能够使代码工作,如果我有一个简单的类与一个主要的方法和静态构造函数.静态构造函数只是调用Boostrapper.Initialize()方法.
之后,我可以使用我的图书馆,它按预期工作：

public static class Test{    static test()    {        bootstrapper.Initialize();    }    public static voID Main()    {         // Using the library here is working fine. The AssemblyResolve event was         // fired (confirmed by a breakpoint in Visual Studio)    }}

我遇到的问题是如果至少有一层依赖关系.基本上代码保持不变,但这次我的库的代码在另一个库中：

public static class Test{    static test()    {        bootstrapper.Initialize();    }    public static voID Main()    {        Class1 myClass = new Class1();        // The following line is using the code of the extracted library,but        // The AssemblyResolve event is not fired (or fired before I register the          // callback) and therefore the library is not found : result          // BadImageFormatException() error Could not load libary because one        myClass.Connect();    }}

听起来像我之前说过的链接的第2条说明了我所看到的东西,但它不起作用. AssemblyResove回调中的Visual Studio断点永远不会被击中.

任何想法发生了什么？

解决方法 我知道已经有一段时间了,因为这个问题被提出和回答,但是我想补充一下我的想法(因为我只是浪费了几个小时,也许感谢这个别人不必)

问题基本上是这样一个事实：应用程序正在尝试解决在该方法开始时执行方法所需的所有程序集：

static voID main(string[] args){    // <-- here the app trIEs to resolve MyAssembly    // and as MyAssembly.Class1 is not found,the app crashes    // this next line is never called:    AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(ResolveAssembly);    // class contained in an assemnly that we need to resolve    MyAssembly.Class1 myClass = new MyAssembly.Class1();}

这就是为什么上面会崩溃的：ResolveAssembly事件处理程序永远不会被调用,因为它从来没有被挂接.

这也是为什么下面的解决方案工作(由OP发布)：

static voID main(string[] args){    Initialize();    RealMain();}static voID Initialize(){    AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(ResolveAssembly);}static voID RealMain(){   // <-- here the app trIEs to resolve MyAssembly   // class contained in an assemnly that we need to resolve         MyAssembly.Class1 myClass = new MyAssembly.Class1();   // and everything is OK}
