推荐答案

然后在循环内部，将字符串"v"拆分为字符串数组，然后再次循环遍历并隐藏它们逐个.

注意:您应该在ID之间使用一些分隔符.我在这里以逗号(，)作为分隔符.

像...

Then inside the Loop, split the String "v" to make it an array of strings and again Loop through them and hide them one by one.

Note: You should have some separator between the Ids. I am taking comma (,) as a Separator here.

Something like...

string[] imageIds = v.Split(',');

foreach(string id in imageIds)
{
    System.Web.UI.WebControls.Image img = (System.Web.UI.WebControls.Image)FindControl(id);
    img.Visible = false;
}

我没有尝试过此代码.让我知道，如果您遇到任何问题.
