问题 C#, VS 2010. Somebody, please explain why I can't use var in my code below! var props = TypeDescriptor.GetProperties(adapter); // error CS1061: 'object' does not contain a definition for 'DisplayName' foreach (var prop in props) { string name = prop.DisplayName; } // No error foreach (PropertyDescriptor prop in props) { string name = prop.DisplayName; } TypeDescriptor.GetProperties returns a PropertyDescriptorCollection with instances of PropertyDescriptor . Why can't the compiler see this?

I have a little problem with default methods in Interface and BeanInfo Introspector. In this example, there is interface: Interface public static interface Interface { default public String getLetter() { return "A"; } } and two classes ClassA and ClassB: public static class ClassA implements Interface { } public static class ClassB implements Interface { public String getLetter() { return "B"; } } In main method app prints PropertyDescriptors from BeanInfo: public static String formatData(PropertyDescriptor[] pds) { return Arrays.asList(pds).stream() .map((pd) -> pd.getName()).collect

I am trying to use a third party jar file within an Android application. I have been able to use some of the classes in the jar file just fine. However, one of the classes references some Java classes that don't appear to be supported by the dalvik vm. These are some of the errors I am seeing in LogCat: Unable to find class referenced in signature java/beans/PropertyDescriptor. Unable to resolve virtual method java/beans/PropertyDescriptor.getName(). Unable to resolve virtual method java/beans/PropertyDescriptor.getReadMethod(). Unable to resolve static method java/beans/Introspector
