In the first version, the backing store is auto-generated by the compiler. Basically saves you some typing and gives you cleaner leaner code.

More info here: Auto-Implemented Properties (C# Programming Guide)[^]

[Edit]
----------

Adding info based on the comments: The private field is generated at compile time, so your code cannot access it. If you need to access it then you need to implement a regular property with a manually implemented backing field.

but to which private member this Property is initializing is not clear ?Actually no private member is involved here. Then ,in this way i may also take public variables too.What makes the special if we use Property in this way ?As far as i know Public Properties are used to get and set values of private members of a class.

The private field is generated by the compiler.

can we get that private field in that class's context ?

Nish Nishant 28-Oct-10 21:07pm

Not sure what you mean. The field is a private member of that class. It's generated at compile time, so you cannot access it in code if that's what you mean.
