推荐答案

尝试： chklstSalary.Items.Count -1

，你使用i代替chklstSalary并且不能与m混合（当您设置所选时）。试试这个：

Try: chklstSalary.Items.Count -1
also, you use i for chklstSalary and cannot mix it with m (when you set the selected). Try this:

if (chklstSalary.Items[i].Value == k[m])
{
   chklstSalary.Items[i].Selected = true;
   break; // no need to loop any further because we already found the matching checkbox
}

祝你好运！

Good luck!

或者你只需​​指定checkboxlist的数据源proprty作为包含值的数组

alternatively u can just specify the datasource proprty of checkboxlist as the array containing values

看起来太复杂了。

我先尝试这样的事情：

Looks too complicated for what it's supposed to do.
I would try something like this first:

char[] delimiter = { ',' };
string[] k = objP.Salary.Split(delimiter, StringSplitOptions.RemoveEmptyEntries);
            foreach (string m in k)
            {
                foreach(item i in chklstSalary)
                {
                   if (i.Value == m)
                    {
                        chklstSalary.i.Selected = true;
                    }
                }
            }
