推荐答案

那里不需要ToCharArray ...

如果您这样声明列表:

There is no need of ToCharArray there...

If you declared your lists like this:

List<string> list1; 
List<string> list2;

那么这个测试就足够了:

Then this test will be enough:

if (list1[0][0] == list2[0][0])
{
    //first chars of first elements are equal
}

否则，请提供有关列表的更多详细信息.

Otherwise, please give more details about your lists.

if(list1[0].ToString().ToCharArray()[0] == list2[0].ToString().ToCharArray()[0]))
{
   //chars are equal 
}
else
{
   //are not
}

怎么样?

How about this???

您可以找到第一个字符ListItem1.SelectedItem.Text.ToCharArray()[0]将为您提供Selected项的第一个字符.

You can find the first char ListItem1.SelectedItem.Text.ToCharArray()[0] will give you the first charecter of the Selected item.
