list

Hello,

why does

List<Object> objectList; = some objects

List<Object> getList() 
{
  return objectList; //or return new List<Object>(objectList);
}

return a list with all items referenced to the original list's items?

Thanks.

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
