The classes in the System. Reflection namespace, together with System.Type, enable to obtain information about loaded assemblies and the types defined within them, such as classes, interfaces, and value types. We can also use reflection to create type instances at run time, and to invoke and access them. For topics about specific aspects of reflection. Assemblies contain modules, modules contain… Read more →

Boxing is used to store value types in the garbage-collected heap. Boxing is an implicit conversion of a value type to the type object or to any interface type implemented by this value type. Boxing a value type allocates an object instance on the heap and copies the value into the new object Boxing Conversion explicit boxing is never required:… Read more →

The as operator is more efficient because it actually returns the cast value if the cast can be made successfully. The is operator returns only a Boolean value. It can therefore be used when we just want to determine an object’s type but do not have to actually cast it. Use the is operator to verify the type before performing a… Read more →
