What’s the difference between encapsulating a private member as a property and defining a property without a private member?

In C#, usually when I define a property I declare and implement a single line or more for get and set. e.g.

public bool IsThere
{
   get { return _isThere; }
   set { _isThere = value;}
}

now what does this mean?

public bool IsThere
{
   get;
   set;
}

Answer 1

Those are auto-properties. They work the same way as your first example, but allow you to omit the unnecessary source code.

They're best used when there is no longer to your getter/setter methods.

They also allow you to add logic to your getter/setter methods later without breaking any calling code (even though you'll also have to implement the private backing property yourself).

Answer 2

It's an Auto-Implemented Property (automatic property).

The C# compiler will automatically create a private field member for the get/set methods to read/write from.

Note that there are limitations to automatic properties (for now). For example, you cannot use modifiers such as readonly, though you can still mark it as private set it isn't quite the same.
