Friend Get and Set is used to Define Property for the class . Property is Used to Modify Private Variables in class .Private variables are normally modifiable only by the functions inside the class .so for modifying it from out side of class we need to define property . in your given example firstName is Private Member so it can only be modified by any class method but what if we want to modify this private variable of class from method out side of class ? . so without Defining the Property you can not modify private Variable of the class from out side method . in property Get Will return the Current value of private variable ans Set Will assing new value to the Private variable friend if my answer helped you to understand the concept simply then check Do you like this answer check box please :)

It is correct what both of the guys said earlier. Nonetheless this is the syntax for implementing properties in C#.

Friend Please be clear about C# concept.It is object oriented. In C# we dontgive direct exposure for private fields again as the best practice fields are made private. We wrap it in a property and expose it to the other classes be declaring it public. It is a art of encapsulation and abstraction. Please let me know if it is not clear still :) Please mark if this helps..... Thanks Paru
