Is there any C# naming convention for a variable used in a property?

Question

Let\'s say, we have a variable, which we want named Fubar

Let\'s say that Fubar is a String!

That means, we would define F

Answer 1

Unluckily there are no common convention, you have to choose what suits most your case, I've seen all the following approaches in different codebases.

Approach 1

private string _fubar;   //_camelCase
public string Fubar { ... }

Approach 2

private string fubar;    //camelCase
public string Fubar{ ... }

Approach 3

private string _Fubar;    //_PascalCase
public string Fubar{ ... }

Also there are frameworks that takes much creativity like using a property and document it as a member variable and thus using member's styling instead of the properties' styling ( yeah Unity! I'm pointing the finger at you and your MonoBehaviour.transform 's property/member)

To disambiguate in our code base we use our homemade rule:

• Try to use more proper naming, usually a member used inside a public property has a slightly different purpose than its public counterpart, so it is very possible most times to find a different and proper name, and if not possible its purpose is just holding state for the public property, so why not naming it nameValue?
• use autoproperties if possible

With our approach most times we avoid the doubt about the underscore "_" while at same time having a much more readable code.

private string fubarValue; //different name. Make sense 99% of times
public string Fubar { ... } 

Answer 2

Another way to declare with a default value

    private string _fubar = "Default Value";
    public string Fubar
    {
        get { return _fubar; }
        set { _fubar = value; }
    }

Answer 3

I thing, one name is better:

public string Fubar { get; private set; }

Answer 4

While most developers follow Microsoft's guideline, as game developers, we follow Unity's style as (one of the script source code here):

static protected Material s_DefaultText = null;
protected bool m_DisableFontTextureRebuiltCallback = false;
public TextGenerator cachedTextGenerator { ... }

Answer 5

I see a ton of outdated answers (and non-standard ways representing C#6), so this one's for 2020:

// "fubar" works, too, but "_" prevents CaSe typo mistakes
private string _fubar;
public string Fubar
{
    get => _fubar;
    set => _fubar = value;
}

// Read-only can just use lambda to skip all those shenannigans
public string ReadOnlyFoo => "This is read-only!";

Answer 6

If there's no logic in the getter/setter, use an auto-property:

public string Fubar {get; set;}
