如何根据键值在checkedlistbox中设置选中项？

// 假设CheckedListBox的名称为checkedListBox1

// 设置数据源
List<KeyValuePair<string, bool>> items = new List<KeyValuePair<string, bool>>();
items.Add(new KeyValuePair<string, bool>("键1", false));
items.Add(new KeyValuePair<string, bool>("键2", true));
items.Add(new KeyValuePair<string, bool>("键3", false));
checkedListBox1.DataSource = items;
checkedListBox1.DisplayMember = "Key";
checkedListBox1.ValueMember = "Value";

// 根据键值设置选中项
string keyValue = "键2";
var selectedItem = items.FirstOrDefault(item => item.Key == keyValue);
if (selectedItem.Value)
{
    checkedListBox1.SetItemChecked(items.IndexOf(selectedItem), true);
}
