Missing methods in WinRT

I want to port a game to WinRT and i have the problem that a few methods are missing. For example System.Type does not contain the methods GetFields and GetMethods. What is the alternative for this on WinRT?

 

Thanks. Is there an way to automatically use TypeInfo instead of Type, when i export to WinRT? So that i just have to change one thing instead of replacing it everywhere?

Edit: Shouldn't it be theoretically possible to do something like this:

Code (CSharp):

1. #if NETFX_CORE
2. using Type = System.Reflection.TypeInfo;
3. #endif

 

I trying to do it now with extension methods, but unfortunately C# does not support extension properties to fix the problem with Type.BaseType

 

Could you maybe give some advice how to do it? I'm not sure how to do it. Everything i tried caused a lot of new trouble

 

What exactly are you trying to do? The easiest thing would be to use implicit typing (var) and use TypeInfo if you're in Windows Store or Windows Phone. You can accomplish this by adding precompiler directives to just execute the code you want. Also, TypeInfo already has a BaseType property:

I first tried to add missing methods on WinRT in Type with extension methods, but then i still had the problems with properties like BaseType, because C# has not extension properties. The problem with explicit typing is that it can be only used in methods. I also don't want to add hundred times precompiler directives into the code to decide what should be executed on which platform.
Unfortunately Type and TypeInfo are not identical so this also does not work:

Code (CSharp):

1. #if NETFX_CORE
2. using Type = System.Reflection.TypeInfo;
3. #endif

My hope is that i can write a class which makes that possible. So i just have to add these three lines to my scripts.

 

How many places in your code are you really using reflection and getting the object types? Maybe there's a better way...

 

I get 99 errors when building for WinRT Most of them are reflection errors. Currently i don't know a better solution

 

That doesn't really explain much. What are you using reflection so much for? What is it that you're doing that requires so much reflection and type resolution?

 

It's not really my code. I'm trying to port UFPS to WinRT

 

I have one more question about porting to WinRT. It's not possible to use delegate.Method on WinRT. How can i replace that?

Edit: It can be replaced with GetMethodInfo()

 

Code (CSharp):

1. namespace System.Reflection
2. {
3.     public static class TypeExtendedMethods
4.     {
5. #if NETFX_CORE
6.         public static FieldInfo GetField(this Type type, string fieldName)
7.         {
8.             if (type == null || string.IsNullOrEmpty(fieldName)) return null;
9.  
10.             var currentType = type;
11.             do
12.             {
13.                 var typeInfo = currentType.GetTypeInfo();
14.                 var declaredField = typeInfo.GetDeclaredField(fieldName);
15.                 if (declaredField != null) return declaredField;
16.                 currentType = typeInfo.BaseType;
17.             } while (currentType != null);
18.             return null;
19.         }
20. #endif
21.     }
22. }

"WinRTLegacy.TypeExtensions has methods GetConstructor(), GetMethod(), GetProperty() for System.Type"

Unity\Editor\Data\PlaybackEngines\metrosupport\Managed\WinRTLegacy.dll (Unity3D v.4.5.5, v.4.6.9)
public methods:
- GetConstructor
- GetGenericArguments
- GetInterfaces
- GetOpImplicitMethodsFromTypeHierarchy
- GetPublicInstanceProperties
- IsSubClassOf
- ReferenceNotEquals
- IsValueType
- EnumToBoolean
- GetTypeCode

Unity3D v.5.2 have implementation for GetField, GetMethod and GetProperty.

 

Yep, this completely bit me with my asset as I started getting ambiguous reference issues, especially when trying to build / use with Windows 10 Universal.
