如何在asp:checkboxlist中获取所选项目

Question

我有一个checkboxlist控件

<asp:CheckBoxList ID="chkselectedItems" Font-Size="12px" runat="server"> 
 </asp:CheckBoxList>

我在动态上创建了一个列表项.如果我从复选框列表中检查了多个项目,我如何使用asp.net获取所选项目数量

谢谢

Answer 1

使用这一行代码:

int selectedCount = chkselectedItems.Items.Cast<ListItem>().Count(li => li.Selected);

Answer 2

编辑

int numSelected = 0;
foreach (ListItem li in chkselectedItems.Items)
{
if (li.Selected)
{
numSelected = numSelected + 1;
}
}
Response.Write("Total Number Of CheckBoxes Selected:");
Response.Write(numSelected);

预

public string[] CheckboxListSelections(System.Web.UI.WebControls.CheckBoxList list)
{
 ArrayList values = new ArrayList();
 for(int counter = 0; counter < list.Items.Count; counter++)
 {
  if(list.Items[counter].Selected)
  {
   values.Add(list.Items[counter].Value);
  }    
 }
 return (String[]) values.ToArray( typeof( string ) );
}
