c# - 根据 Switch 语句获取值

Question

在 C# 中是否可以根据 switch 语句获取值？

public int NumCandyBars (string candyBar)
{
    get {

        switch (candyBar)
        {
            case "twix":
                    { return _numTwix; }
            case "snickers":
                    return _numSnickers;
            case "kitkat":
                return _numKitKat;

            default: return 0;
        }                
    }
}

所以上面的代码应该返回一个基于它的字符串类型的值。

    public int NumCandyBars (string candyBar)
    {
        int retval = 0;
        switch (candyBar)
        {
            case "twix":
                retval = _numTwix;
                break;
            case "snickers":
                retval =_numSnickers;
                break;
            case "kitkat":
                retval = _numKitKat;
                break;
        }
        return retval;
    }
