What is the difference between a field and a property in C#
Should I use public properties and private fields or public fields for data?

What is the difference between:

public string varA;

and

public string varA { get; set; }

Answer 1

The public property accessor gives you more flexibility in the future.

If you want to add validation to setting the value, you simply write a non-default setter. None of your other code would have to be modified.

There could also be reasons you’d want to replace the default getter with code. That can be a real pain with a public variable.
