How should I use Properties in C#?

Question

Im not sure because in Java getter/setter are looking a little bit different but whats the "c# way" to code this stuff?

Option a.)

    private string name;

    public string Name
    {
        get { return name; }
        set { name = value; }
    }

    private int time;

    public int Time
    {
        get { return time; }
        set { time = value; }
    }

b.)

    private string _name;
    private int _time;

    public string name
    {
        get { return _name; }
        set { _name = value; }
    }

    public int time
    {
        get { return _time; }
        set { _time = value; }
    }

c.)

   public string name {get; set;}
   public int time {get; set;}

Ok there are some examples. What would look better? Should I write all the private variable declarations first then the properties or should I group my variable and property declaration next to each other.

Answer 1

How about d, following .NET naming conventions:

public string Name { get; set; }
public int Time { get; set; } // Odd type for time, admittedly...

Don't bother writing the property manually yourself unless you do something non-trivial in it.

If you do write the property implementation manually, it's up to you how you name the private variable. Personally I'd use:

private string name;
public string Name
{
    get { /* whatever */ }
    set { /* whatever */ }
}

... but if you want to use underscores, that's your prerogative.

As for ordering of members - that's even more your own choice. Assuming you're working with a team, talk with the team and see what the local convention is.
