问题描述

错误在于：

The error is with:

highscores[0] = new Percentage("098", "2014/02/01", "78");
highscores[1] = new Percentage("078", "2014/05/15", "68");
highscores[2] = new Percentage("045", "2014/09/16", "71");

代码：

Code:

public class Percentage
{
    public string id { get; set; }
    public string DateTime { get; set; }
    public string Percent { get; set; }
}
protected void btn2(object sender, EventArgs e)
{
    Percentage[] highscores = new Percentage[3];
    highscores[0] = new Percentage("098", "2014/02/01", "78");
    highscores[1] = new Percentage("078", "2014/05/15", "68");
    highscores[2] = new Percentage("045", "2014/09/16", "71");
    highscores = highscores.OrderByDescending(s => s.Percent).ToArray();

    GridView1.DataSource = highscores;
    GridView1.DataBind();
}

错误代码：

Error code:

'theScore._Default.Percentage' does not contain a constructor that takes 3 arguments	C:\Users\user\path\Default.aspx.cs

推荐答案

protected void btn2(object sender, EventArgs e)
       {
           List<percentage> objPercentage = new List<percentage>();
           objPercentage.Add(new Percentage{ id="098", DateTime="2014/02/0", Percent="78"});
           objPercentage.Add(new Percentage{ id="099", DateTime="2014/02/0", Percent="68"});
           objPercentage.Add(new Percentage{ id="099", DateTime="2014/02/0", Percent="68"});

           GridView1.DataSource = objPercentage;
           GridView1.DataBind();
       }
