Question

I think it was in .net 2.0, microsoft introduced an accessor that was abbreviated to something like

public string Name { get; set; }

But is there any real difference between the above code, and simply:

public string Name;

Answer 1

The main difference is that if you later need to add logic into your getter or setter, and other DLLs have already been compiled against yours, you can easily change

public string Name { get; set; }

into

public string Name { get{/*special code*/} set{/*special code*/} }

and it won’t be a breaking change to publish your new DLL and have other DLLs not be recompiled.

Whereas if you changed

public string Name;

into

public string Name { get{/*special code*/} set{/*special code*/} } 

then you’ll need to make sure any DLLs that use yours are recompiled, since they change from accessing a field into accessing a property.

This is obviously a bigger problem when you’re shipping DLLs to other programmers (as an open source project or as a component vendor for example) than if you’re just building an app for your own self / employer
