我在前几天发现了一个堆栈溢出的帖子的答案。虽然我没有保存该链接。但下面的解决方案解决了我的问题
foreach (Tripclass Trip in TripsByTripIds )
{
ImageButton imageButton = new ImageButton();
imageButton.ImageUrl = "~/" + Trip.CorridorName + "/" + Trip.Time + "/" + Trip.ImgFileName;
imageButton.Height = Unit.Pixel(100);
imageButton.Style.Add("padding", "5px");
imageButton.Width = Unit.Pixel(100);
imageButton.Click += new ImageClickEventHandler((a, b) => imageButton_Click(a, b,Trip));
AMSPanel1.Controls.Add(imageButton);
AMSPanel1.Height = Unit.Pixel(860);
}
protected void imageButton_Click(object sender, ImageClickEventArgs e, Tripclass Trip)
{
testimage.ImageUrl = ((ImageButton)sender).ImageUrl;
lblTime.Text = Trip.Time;
lblLocation.Text = Trip.Location; //I can access trip object here
}

如果可以将其表示为文字,则可以将您的值添加到CommandArgument属性
