我对在 .Net-Core 中动态附加代码很感兴趣。 注意：这仅用于教育目的。

目前我有一个交换方法的类：

public static void Inject<TTarget, TInject>(string targetFuncName, string injectFuncName)
{
    MethodInfo methodToReplace = typeof(TTarget).GetMethod(targetFuncName, BindingFlags.Instance | BindingFlags.Static | BindingFlags.NonPublic | BindingFlags.Public);
    MethodInfo methodToInject = typeof(TInject).GetMethod(injectFuncName, BindingFlags.Instance | BindingFlags.Static | BindingFlags.NonPublic | BindingFlags.Public);
    RuntimeHelpers.PrepareMethod(methodToReplace.MethodHandle);
    RuntimeHelpers.PrepareMethod(methodToInject.MethodHandle);

    unsafe
    {
        if (IntPtr.Size == 4)
        {
            int* inj = (int*)methodToInject.MethodHandle.Value.ToPointer() + 2;
            int* tar = (int*)methodToReplace.MethodHandle.Value.ToPointer() + 2;
#if DEBUG
            Console.WriteLine("\nVersion x86 Debug\n");

            byte* injInst = (byte*)*inj;
            byte* tarInst = (byte*)*tar;

            int* injSrc = (int*)(injInst + 1);
            int* tarSrc = …
