将标签中的文本与列表框中的一行相关联 [英] associating text in a label to a line in a listbox
问题描述
如何将标签中显示的数字与列表框中的一行相关联?
How do I associate the number displayed in a label with a line in a listbox?
例如:如果lblShowNumber.Text = 1,则列表框中的第一行= 1.
for example: if lblShowNumber.Text=1 then the first line in a listbox = 1.
我知道第一行从0开始.
I know that the first line started at 0.
推荐答案
例如:如果lblShowNumber.Text = 1,则列表框中的第一行= 1.
for example: if lblShowNumber.Text=1 then the first line in a listbox = 1.
不清楚列表框中的第一行= 1"是什么意思.如果要滚动列表框的内容,以使第1行位于显示的顶部,请使用TopIndex属性. 参阅:

It's not clear what you mean by "the first line in a listbox = 1". If you mean to scroll the list box contents so that line 1 is at the top of the display, use the TopIndex property. See:

如果您还有其他意思,请提供您正在尝试做的事情的详细说明.
If you mean something else, provide more description of what you are trying to do.
请注意,您不应使用标签文本来设置列表框的第一行.标签文本是通过某个变量设置的-该变量应用于列表框管理,而不是标签文本.
Please note that you should not use the label text to set the listbox first line. That label text was set from some variable - that variable should be used for the listbox management instead of the label text.
