Question

我有我的gridview设置，用户可以“选择”他们想要的行，而这些行又应该通过数据库并重定向它们。但是，当我点击任何给定行结果的“select”时，我在此行收到错误“输入字符串格式不正确”：myEvent.EventID = Convert.ToInt32（row.Cells [0] .Text）;我把这篇文章拿出去了，我得到了错误，因为转换中包含了它。所以我知道它写得不正确，但我不确定如何写它。任何帮助都会很棒！

抱歉，我是新手！

我的girdview代码：

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
    {
        Event myEvent = new Event();
        GridViewRow row = GridView1.SelectedRow;
        myEvent.EventID = Convert.ToInt32(row.Cells[0].Text);
        myEvent.Sport = row.Cells[1].Text;
        myEvent.EventName = row.Cells[2].Text;
        myEvent.Section = Convert.ToInt32(row.Cells[3].Text);
        myEvent.TicketsAvailable = Convert.ToInt32(row.Cells[4].Text);
        myEvent.EventDate = Convert.ToDateTime(row.Cells[5].Text);
        Session["myEvent"] = myEvent;

        Response.Redirect("Complete.aspx");
    }

我需要的事件代码：

public class Event
{
    public int EventID { get; set; }
    public string EventName { get; set; }
    public string Sport { get; set; }
    public int Section { get; set; }
    public int TicketsAvailable { get; set; }
    public DateTime EventDate { get; set; }
}

只需检查天气，您要转换的值不为空。尝试调试代码并检查从该特定行获得的值是什么。

另一件事是，如果您在gridview中创建了生成的选择按钮，则该选择按钮的位置位于gridview的0格。所以你可以尝试这样的代码。

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
    {
        Event myEvent = new Event();
        GridViewRow row = GridView1.SelectedRow;
        myEvent.EventID = Convert.ToInt32(row.Cells[1].Text);
        myEvent.Sport = row.Cells[2].Text;
        myEvent.EventName = row.Cells[3].Text;
        myEvent.Section = Convert.ToInt32(row.Cells[4].Text);
        myEvent.TicketsAvailable = Convert.ToInt32(row.Cells[5].Text);
        myEvent.EventDate = Convert.ToDateTime(row.Cells[6].Text);
        Session["myEvent"] = myEvent;

        Response.Redirect("Complete.aspx");
    }

选择gridview行/单元格错误“输入字符串格式不正确”
