you can try the following
您可以尝试以下操作
List<X> x2 = chkList.CheckedItems.OfType<X>().ToList();
or cast as object
或投射为对象
List<object> x2 = chkList.CheckedItems.OfType<object>().ToList();

Here is a way that works for me:
这是一种对我有用的方法：
List<X> x2 = new List<X>();
x2 = chkList.CheckedItems.Cast<X>().ToList();

string[] miList = chkList.CheckedItems.OfType<object>().Select(li => li.ToString()).ToArray();

This is another Option
这是另一个选项
List<X> lst = new List<X>(chkList.CheckedItems.Cast<X>());
