What's the purpose to use Property with set and get to change a field?
-
Let me give you the strong need of property in C#. Suppose there's one field
CustomerIDand you have assignedCustomerIDPropertyto get and set values forCustomerID. Now After a years requirements being changed and They say they need some validation onCustomerIDnow you can not change or not advisable to put a check ofCustomerIDeverywhere in the code, At that time you can simply put check at set method of CustomerIDProperty to be rescued. Property is introduced because of the changing requirement in software field. "Walking on water and devloping a software both are the easy things,Provided both FROZEN".Regards, Hiren.

Property was introduced just as a convenience, not because of any need. The change requirement could easily be implemented with normal methods as in C++. It's a quicker way to code for the developer, it's a quicker way to call for the consumer (no parentheses required), offers an auto-generation option, and signifies intent of the developer with fewer comments (a property is used when there is little calculation and no side effects). None of these are necessary though.

Also that Interfaces can specify properties, but not fields.

It also gives hints at what to look for when reflecting through an object. IE Some asp.net data grids will auto bind columns to all properties of an object.

That's true and good point, but that's a .NET issue that wasn't applicable to C++.

The point is to answer in context of the OP's questions, and if you had taken the time you spent on your clever sarcasm and spent it on reading all the OP's posts instead, you'd know he was coming from an OO background from C++. So I think you need to decide if you want to help someone with a question in context, or if you want to show off your mad skilz :) The OP said "I am wondering if that is a Microsoft's "invention" or a general OOP thinking. I never met it in C++." By way of my response to you, I was telling him that data grid data binding with properties is a Microsoft-specific invention for C#/.NET, and not general OOP thinking. I replied to your post to help him and the lurkers, not educate you. But as a token of goodwill, I'm still willing to educate you. You misused "IE" in your previous post. :) You might want to look that one up.

There was no sarcasm intended, I just saw your reply in my email and truly thought I had made a reply in the wrong forum. There was no intent of sarcasm or showing of my "mad skilz". I will choose to take your token of goodwill as that and not passive aggression; in the future will use eg. instead of ie. in those cases. Thanks.
