推荐答案

HI Narasiman



你可以这样做

创建一个隐藏字段在aspx页面中

你可以在逗号分隔的字符串<中存储列表项 / code>到隐藏字段。





HI Narasiman

you can do like this
create a hidden field in the aspx page
and you can store the list items in comma separated string to the hidden field.

for (int i = 0; i < ListBox1.Items.Count; i++)
               {
                   hdnfld.Value += ListBox1.Items[i].Text + ",";
               }
