Properties are one of the nicest mechanisms within C# and the CLR that enable you to enforce encapsulation better. In short, we use properties for strict control of access to the internal state of an object.

There are a few reasons to use properties, instead of public fields/methods. (i) Properties can be virtual. (ii) You can make the setters for a property private. (iii) Properties have a 'special' meaning to things that inspect classes at runtime. See this link http://www.itorian.com/2012/07/properties-in-c-howwhy-we-use-this.html
