C# 4.0 Can'；t hook ICorJitCompiler：从托管代码中使用EasyHook进行编译的方法

我一直在尝试使用EasyHook LocalHook.Create从v4.0中的托管代码中钩住

ICorJitCompiler:compileMethod

。我从如下结构的解组中获得了函数指针：

public static class NativeJitInterop
{
    [DllImport("clrjit.dll", CharSet=CharSet.None, SetLastError = true)]
    private static extern IntPtr getJit();

public static ClrJitCompilerHook GetManagedJitCompiler()
{
    ClrJitCompilerHook clrJitCompiler = null;

    IntPtr _clrJitPtr = getJit();

    ICorJitCompiler _corJitCompiler = (ICorJitCompiler)  Marshal.PtrToStructure(_clrJitPtr, typeof(ICorJitCompiler));
    clrJitCompiler = new ClrJitCompilerHook(_clrJitPtr, _corJitCompiler.compileMethod);

    return clrJitCompiler;
}    


[StructLayout(LayoutKind.Sequential)]
internal struct ICorJitCompiler
{
    [MarshalAs(UnmanagedType.FunctionPtr)]
    public CompileMethodSig compileMethod;

}

[UnmanagedFunctionPointer(CallingConvention.StdCall, SetLastError = true)]
internal delegate Int32 CompileMethodSig(IntPtr thisPtr, IntPtr corJitInfo, IntPtr methodInfo, UInt32 flags, [Out] IntPtr ILCode, [Out] UInt64 ILCodeSize);

public void HookClrJitCompiler()
{
    IntPtr _compileMethodPtr = Marshal.GetFunctionPointerForDelegate(_compileMethodDelegate);

    _localJitHook = LocalHook.Create(_compileMethodPtr, new CompileMethodSig(ClrJitCompilerCalled), this);

    _localJitHook.ThreadACL.SetExclusiveACL(new Int32[] { 0 });
}

一切正常，结构似乎没有问题，并且包含的委托的_methodPtr和_methodPtrAux字段填充了一些指针值

当我尝试像这样设置钩子时，问题出现了：

public static class NativeJitInterop
{
    [DllImport("clrjit.dll", CharSet=CharSet.None, SetLastError = true)]
    private static extern IntPtr getJit();

public static ClrJitCompilerHook GetManagedJitCompiler()
{
    ClrJitCompilerHook clrJitCompiler = null;

    IntPtr _clrJitPtr = getJit();

    ICorJitCompiler _corJitCompiler = (ICorJitCompiler)  Marshal.PtrToStructure(_clrJitPtr, typeof(ICorJitCompiler));
    clrJitCompiler = new ClrJitCompilerHook(_clrJitPtr, _corJitCompiler.compileMethod);

    return clrJitCompiler;
}    


[StructLayout(LayoutKind.Sequential)]
internal struct ICorJitCompiler
{
    [MarshalAs(UnmanagedType.FunctionPtr)]
    public CompileMethodSig compileMethod;

}

[UnmanagedFunctionPointer(CallingConvention.StdCall, SetLastError = true)]
internal delegate Int32 CompileMethodSig(IntPtr thisPtr, IntPtr corJitInfo, IntPtr methodInfo, UInt32 flags, [Out] IntPtr ILCode, [Out] UInt64 ILCodeSize);

public void HookClrJitCompiler()
{
    IntPtr _compileMethodPtr = Marshal.GetFunctionPointerForDelegate(_compileMethodDelegate);

    _localJitHook = LocalHook.Create(_compileMethodPtr, new CompileMethodSig(ClrJitCompilerCalled), this);

    _localJitHook.ThreadACL.SetExclusiveACL(new Int32[] { 0 });
}

我获取并访问ViolationException

我解决了这个问题，并将

\u compileMethodPtr

变量设置为委托的

\u methodPtr

。我在上钩时没有例外，但钩子也不起作用

我做错了什么
