如何在C＃中以字符串格式替换double？

Question

如何用double替换字符串来计算C＃中下面代码中的“距离”（而不是时间）？距离最初为0.00。试图通过Windows Phone中的Sqlite发布值。

private string time = string.Empty;
        public string Time
        {
            get { return time; }
            set { if (SetProperty(ref time, value)) IsDirty = true; }
        }

//需要将值放在下面的行中。

internal CustomerViewModel(int id, double pace, string time, double distance )
        {
            this.id = id;
            this.pace = pace;
            this.time = time;
            this.distance = distance;                      
            this.isDirty = false;
        }

Answer 1

我不知道我是否理解你的问题，但这就是你的意思：

private double time = 0.00;
    public double Time
    {
        get { return time; }
        set { if (SetProperty(ref time, value)) IsDirty = true; }
    }

修改

private double distance = 0.0;
    public double Distance
    {
        get { return this.distance; }
        set { 
            this.distance = value;
            IsDirty = true; }
    }
