如何取消选中checkedListBox1并正确编写字符串？ [英] How to uncheck checkedListBox1 and write the string properly?

问题描述

我有checkedListBox1控件。我想写成一个字符串checked3487，只有选中的复选框文本。 （复选框附近的文字）。

当我按下一个复选框时，检查​​状态直到ItemCheck事件发生后才更新，但是if（e.NewValue == CheckState.Checked） ）正在实时更新检查状态，但仅针对Checked状态。

当我UNCHECK时，它会在2次点击鼠标后更新（在ItemCheck事件发生后）。

如何正确取消选中并写入字符串？



我在google上搜索过，我做了10种不同的编码变种，我绝望了。我想念的是什么？

I have checkedListBox1 control. I want to write into a string "checked3487", ONLY the checked checkboxes text. (the text near the checkbox).
When I press one checkbox, "The check state is not updated until after the ItemCheck event occurs", but the "if (e.NewValue == CheckState.Checked)" is updating in realtime the check state, but only for the Checked state.
When I UNCHECK, it is updating after 2 click of the mouse, (after the ItemCheck event occurs).
How to uncheck and write the string properly?

Ive searched on google, I done 10 different variants of coding, and im desperate. What I miss?

string checked3487 = ""; List<string> checkedList = new List<string>();
private void checkedListBox1_ItemCheck(object sender, ItemCheckEventArgs e)
      {
          listBox1.Items.Clear(); checked3487 = ""; checkedList.Clear();

          foreach (var item in checkedListBox1.CheckedItems)
              checkedList.Add(item.ToString());

          if (e.NewValue == CheckState.Checked)
          {
              checkedList.Add(checkedListBox1.Items[e.Index].ToString());
          }
          if (e.NewValue == CheckState.Unchecked)
          {
              //?????????????????????????????????????????????????????????????????????/
          }



          foreach (string item in checkedList)
          {
              checked3487 += item;
          }
       }

现在正在工作！

这是一个字符串毕竟是操纵。该死的。

我得到了启发，我找到了解决方案。

这里是：

Now is working!
it was a string manipulation after all. Damn it.
I got inspired and I find the solution.
here it is:

if (e.NewValue == CheckState.Unchecked)
{
    if (checkedList.Contains(checkedListBox1.Items[e.Index].ToString()))
    {
        int i = checkedList.IndexOf(checkedListBox1.Items[e.Index].ToString());
        checkedList.RemoveAt(i);
    }
}
