I ran the simple boxing test below on Mono 2.10.12 and 3.1.2 and don't
understand why the ToString results on the boxed object do not match the
unboxed value.
I can also pass the MonoObject into mono_runtime_invoke to have a C# method on
the other side call ToString and it shows the correct value.
Is there a known issue with mono_object_to_string or am I doing something
incorrectly?
Thanks!
// Int Marshalling
int32_t v = 10;
printf("original value = %d\n", v);
MonoObject *obj = mono_value_box(mono_domain_get(), mono_get_int32_class(), &v);
MonoString *obj_string = mono_object_to_string(obj, NULL);
char *obj_string_utf8 = mono_string_to_utf8(obj_string);
printf("boxed value = %s\n", obj_string_utf8);
g_free(obj_string_utf8);
v = *(int32_t*)mono_object_unbox(obj);
printf("unboxed value = %d\n", v);
// Output
// original value = 10
// boxed value = 85441552 <-- Huh?
// unboxed value = 10
// Bool Marshalling
int8_t b = 0;
printf("original value = %d\n", b);
obj = mono_value_box(mono_domain_get(), mono_get_boolean_class(), &b);
obj_string = mono_object_to_string(obj, NULL);
obj_string_utf8 = mono_string_to_utf8(obj_string);
printf("boxed value = %s\n", obj_string_utf8);
g_free(obj_string_utf8);
b = *(int8_t*)mono_object_unbox(obj);
printf("unboxed value = %d\n", b);
// Output
// original value = 0
// boxed value = True <-- 0 == True ?
// unboxed value = 0_______________________________________________
