我是用遍历的方法取得选中的数据,只要这样就可以了
foreach (ListItem Item in checkedListBox.Items)
{
if(!Item.Selected)
{
string ddd += Item.Value.ToString() + ",";
}
}
foreach (ListItem Item in checkedListBox.Items)
{
if(!Item.Selected)
{
string ddd += Item.Value.ToString() + ",";
}
}
private void WhatIsChecked_Click(object sender, System.EventArgs e) {
// Display in a message box all the items that are checked. // First show the index and check state of all selected items.
foreach(int indexChecked in checkedListBox1.CheckedIndices) {
// The indexChecked variable contains the index of the item.
MessageBox.Show("Index#: " + indexChecked.ToString() + ", is checked. Checked state is:" +
checkedListBox1.GetItemCheckState(indexChecked).ToString() + ".");
} // Next show the object title and check state for each item selected.
foreach(object itemChecked in checkedListBox1.CheckedItems) { // Use the IndexOf method to get the index of an item.
MessageBox.Show("Item with title: \"" + itemChecked.ToString() +
"\", is checked. Checked state is: " +
checkedListBox1.GetItemCheckState(checkedListBox1.Items.IndexOf(itemChecked)).ToString() + ".");
}}
"ListItem" 这个类在怎么引用啊?
在C #中提示:
找不到类型或命名空间名称“ListItem”(是否缺少 using 指令或程序集引用?)
