dependency-injection

I have been looking at the terms constructor injection and dependency injection while going through articles on (Service locator) design patterns.

When I googled about constructor injection, I got unclear results, which prompted me to check in here.

What is constructor injection? Is this a specific type of dependency injection? A canonical example would be a great help!

Edit

Revisiting this questions after a gap of a week, I can see how lost I was... Just in case anyone else pops in here, I will update the question body with a little learning of mine. Please do feel free to comment/correct. Constructor injection and property injection are two types of Dependency Injection.

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
