CheckedListBox获取所选索引

Question

如何在CheckedListBox中获取所选索引的值。我尝试了通过一个if条件和切换案例，但它并不像预期的那样工作。

private void checkedListBox1_SelectedIndexChanged(object sender, EventArgs e)
{            
   if (checkedListBox1.GetItemCheckState(0)==CheckState.Checked)
   {                               
      richTextBox1.Font = new Font(richTextBox1.Font, FontStyle.Bold);
   }
}

Answer 1

我想你可以用

    checkedListBox1.CheckedIndices

就像这样

    foreach(int index in checkedListBox1.CheckedIndices)
    {
    if(index == 1)
    {
          //do something
     }
  }

Answer 2

试试这个：

if(checkedListBox1.CheckedItems.Count != 0)  
{  
   // If so, loop through all checked items and print results.  
   string s = "";  
   for(int x = 0; x <= checkedListBox1.CheckedItems.Count - 1 ; x++)  
   {  
      s = s + "Checked Item " + (x+1).ToString() + " = " + checkedListBox1.CheckedItems[x].ToString() + "\n";  
   }  
MessageBox.Show (s);  
}
