Is there a way in C# where I can use reflection to set an object property? Ex: MyObject obj = new MyObject(); obj.Name = "Value"; I want to set obj.Name with reflection. Something like: Reflection.
Reflection is the specific name for how .NET implements introspection. Other languages may call it something different (C++ calls its limited introspection RTTI, for run-time type information).
There are two kinds of reflection swimming around. Inspection by iterating over members of a type, enumerating its methods and so on. This is not possible with C++. Inspection by checking whether a class-type (class, struct, union) has a method or nested type, is derived from another particular type. This kind of thing is possible with C++ using template-tricks. Use boost::type_traits for many ...

Reflection performance will depend on the implementation (repetitive calls should be cached eg: entity.GetType().GetProperty("PropName")). Since most of the reflection I see on a day to day basis is used to populate entities from data readers or other repository type structures I decided to benchmark performance specifically on reflection when it is used to get or set an objects properties. I ...
Within "Common", I have a class for common reflection tasks, like creating an instance. If I call GetExecutingAssembly, it gets all the "Common" Types, however when I use GetEntryAssembly I get the "Program" types.
