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.
I have not tried this code. Let me know, if you face any issues.
