为什么我得到一个＆QUOT;不包含一个构造函数的参数0＆QUOT;错误？ C＃

在我的形式加载，我有这样的code：

On my form load, I have this code:

    private void Form1_Load(object sender, EventArgs e)
    {
        CharityCyclists cyclist1 = new CharityCyclists();
        CharityCyclists cyclist2 = new CharityCyclists("a", 1, "Finished", 0, 0, 0, "One Wheel", 1, 500);

        cyclist1.Type = "Novelty Charity Cyclist";
        cyclist1.Number = 1;
        cyclist1.Finished = "Not Finished";
        cyclist1.Hours = 0;
        cyclist1.Mins = 0;
        cyclist1.Secs = 0;
        cyclist1.Bicycle = "Tricycle";
        cyclist1.Wheels = 3;
        cyclist1.FundsRaised = 300;
    }

不过，我得到一个错误说'CycleEvent.CharityCyclists'不包含一个构造函数的参数0，它说的错误与code的这部分做的：

However, I'm getting a error saying "'CycleEvent.CharityCyclists' does not contain a constructor that takes 0 arguments", it says the error is to do with this part of the code:

CharityCyclists cyclist1 = new CharityCyclists();

下面是我的CharityCyclists类：

Here is my CharityCyclists class:

class CharityCyclists : Cyclists
{
    private string bicycle;
    private int wheels;
    private double fundsRaised;

    public string Bicycle
    {
        get { return bicycle; }
        set { bicycle = value; }
    }

    public int Wheels
    {
        get { return wheels; }
        set { wheels = value; }
    }

    public double FundsRaised
    {
        get { return fundsRaised; }
        set { fundsRaised = value; }
    }

    public CharityCyclists(String type, int number, String finished, int hours, int mins, int secs, string bicycle, int wheels, double fundsRaised) : base(type, number, finished, hours, mins, secs, fundsRaised)
    {
        this.bicycle = bicycle;
        this.wheels = wheels;
        this.FundsRaised = fundsRaised;
    }

    public override string ToString()
    {
        return base.ToString() + " riding a " + bicycle + " with " + wheels + " wheels" ;
    }
}

谢谢！
