I embedded Mono runtime 3.12 in my QT c++ app on Os x 10.8.5 and try to get
generic class in my c++ app.
Case 1:
c#
namespace TestDictionary
{
public class Class1
{
public Dictionary<string,object> DictionaryField;
public static void Dump (Dictionary <string, object> dictionary)
{
Console.WriteLine("Dump called\n");
}
public static void Main()
{
Console.WriteLine("Class1 Main called!\n");
}
}
}
c++
MonoClass* classDictionary = NULL;
classDictionary = mono_class_from_name(image, "TestDictionary",
"Class1");
I compiled TestDictionary.exe and classDictionary is non-NULL.
Case 2:
c#
namespace TestDictionary
{
public class Class1
{
public Dictionary<string,object> DictionaryField;
public static void Dump (Dictionary <string, object> dictionary)
{
Console.WriteLine("Dump called\n");
}
}
}
namespace Playstkop.Toolbox
{
public class ToolboxFacade
{
public static void Main()
{
Class1 testClass1 = new Class1();
Console.WriteLine("ToolboxFacade Main called!!\n");
}
}
}
c++
MonoClass* classDictionary = NULL;
classDictionary = mono_class_from_name(image, "TestDictionary",
"Class1");
I compiled TestDictionary.dll and Playstkop.Toolbox.exe. classDictionary
returns NULL. I digged into mono_class_from_name and found that the value of
'name' is 0x0 instead of "Class1".
Locals

This is the Locals when 'mono_class_from_name' returns:
Locals

buf " ݯ\013\001\000\000\000@ú\..." char [1024]

nspace_table 0x0 GHashTable *
pos @0xffffffffffffffff int
res @0xffffffffffffffff gboolean
t 0x0 MonoTableInfo *
token 0 guint32
I go back to Case 1 and trace the method 'mono_class_from_name'. The value
of 'name' is also 0x0 (Surprised!).
Locals
assembly_idx @0xffffffffffffffff guint32
buf " ý§\013\001\000\000@..." char [1024]
class 0x0 MonoClass *
class@1 0x0 MonoClass *

nspace_table 0x0 GHashTable *

However, when 'mono_class_from_name' returns, Class1 is returned.

Here I did something wrong or understood wrong? Any advice helps. Thanks!
