How to get the direct function pointer of virtual struct method?

This works.

public static IntPtr GetMethodPointer(MethodInfo methodInfo)
{
     var dynamicMethod = new DynamicMethod("GetFunctionPointer", typeof(IntPtr), [], typeof(MdInternal).Module);
     var il = dynamicMethod.GetILGenerator();
     il.Emit(OpCodes.Ldftn, methodInfo);
     il.Emit(OpCodes.Ret);
     return (IntPtr)dynamicMethod.Invoke(null, null)!;
}

public static IntPtr GetMethodPointer(MethodInfo methodInfo)
{
     var dynamicMethod = new DynamicMethod("GetFunctionPointer", typeof(IntPtr), [], typeof(MdInternal).Module);
     var il = dynamicMethod.GetILGenerator();
     il.Emit(OpCodes.Ldftn, methodInfo);
     il.Emit(OpCodes.Ret);
     return (IntPtr)dynamicMethod.Invoke(null, null)!;
}
