推荐答案

您循环浏览所有复选框，并使其变为"CHECK ALL"(全部检查)

You loop through all checkboxes and make them "CHECK ALL"

if(boolAllChecked)
 {
     foreach (ListItem listItem in checkListbox1.Items)
     {
          listItem.Selected = false;
     }
 }
 else 
 {
     foreach (ListItem listItem in checkListbox1.Items)
     {
          listItem .Selected = true;
     }
 }
