我一直在苦苦钻研AssenblyResolve事件。我已经搜索了stackoverflow和做了其他谷歌搜索,尝试了我认为相关的所有内容。以下链接是我认为与我的问题最接近(仅为我个人意见):
我有一个Bootstrapper类,其中有两个静态方法(出于清晰起见,我将删除我们拥有的线程安全代码):
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;
}
}
如果我有一个带有主方法和静态构造函数的简单类,那么我就能够使代码工作。静态构造函数只是调用了Boostrapper.Initialize()方法。之后,我就可以使用我的库,它能够按照预期工作:
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)
}
}
我的问题在于如果存在至少一个依赖层。基本上代码保持不变,但这次我的库的代码位于另一个库内:
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();
}
}
听起来我之前提到的链接中的第二个解释了我的问题,但它并没有起作用。在AssemblyResove回调上,Visual Studio断点从未被触发。
有任何想法吗?
