使用 mono_assemble_load_from 加载程序集时如何获取程序集？

Question

我使用 Mono 方法将程序集加载到应用程序中。问题是，当我加载程序集时，我只得到

IntPtr

，但我需要

System.Reflection.Assembly

。如何使用

IntPtr

获得它？

我导入和使用的方法：

public static class MonoCalls {
    [DllImport("__Internal", EntryPoint = "mono_image_open_from_data")]
    public static extern IntPtr MonoImageOpenFromData(IntPtr dataHandle, int dataLenght, bool shouldCopy, IntPtr status);

    [DllImport("__Internal", EntryPoint = "mono_assembly_load_from")]
    public static extern IntPtr MonoAssemblyLoadFrom(IntPtr imageHandle, string name, IntPtr status);
}

用于将程序集加载到内存中的类（输入是字节数组形式的程序集）：

public class Mono {
    IntPtr Image;
    IntPtr Assembly;
    public IntPtr Activate(byte[] Bytes) {
        unsafe {
            fixed (byte* Pointer = Bytes) {
                Image = MonoCalls.MonoImageOpenFromData((IntPtr)Pointer, Bytes.Length, true, IntPtr.Zero);
                Assembly = MonoCalls.MonoAssemblyLoadFrom(Image, string.Empty, IntPtr.Zero);
                return Assembly;
            }
        }
    }
}

主要代码：

...

Mono Mono = new();
byte[] Assembly_Bytes = ...; // Assembly
IntPtr Pointer = Mono.Activate(Assembly_Bytes);
string MyAssemblyName = "MyAssembly";

Assembly FoundAssembly;
foreach (Assembly Assembly in AppDomain.CurrentDomain.GetAssemblies()) {
    if (Assembly.GetName().Name.Equals(MyAssemblyName)) {
        FoundAssembly = Assembly; // Got it (or an assembly with similar name)
        return;
    }
}

Type[] Types = FoundAssembly.GetTypes(); // Main purpose of this part of code
...

有没有像

GetAssemblyByPtr(IntPtr)

这样返回

System.Reflection.Assembly

的方法？

*简单

Assembly.Load()

不适合我的情况。

Answer 1

在加载程序集之前，如果我收到程序集，我会绑定到程序集加载事件。加载后，事件解除绑定。

主要代码：

...
AppDomain.CurrentDomain.AssemblyLoad += CurrentDomain_AssemblyLoad;
...
// Loading assemblies
// It's supposed to load only the assemblies I need at the moment.
...
AppDomain.CurrentDomain.AssemblyLoad -= CurrentDomain_AssemblyLoad;
...

private void CurrentDomain_AssemblyLoad(object Sender, AssemblyLoadEventArgs AssemblyLoadEventArgs) {
    Console.WriteLine("CurrentDomain_AssemblyLoad");
    Assembly MyAssembly = AssemblyLoadEventArgs.LoadedAssembly;
    // Got loaded assembly (or assemblies)
}
