您可以创建一个自定义选取框标签，该标签使用计时器并重绘自身并从左到右或从上到下为文本设置动画，如下所示

I'm making a desktop application in C# which contains a moving News Bar labels. I'm using a timer to move these labels but the problem is that when i make the interval of this timer low (1-10 for example) the application takes very high percentage of CPU Usage, And when i make it higher(200 -500 ) the movement of the labels becomes intermittent or not smooth movement even that the user may not be able to read the news in Comfortable way.

((More Information)) it is Windows form application. the way i move the labels is as follows : the news items from RSS feeds are represented in a group of linklabels. All these linklabels are added to a flowlayout container. The timer moves the whole flowlayout container. I found this way according to my knowledge the best way to making the news bar. If you have better idea or solution please help.

解决方案

You can create a custom marquee label which uses a timer and redraw itself and animates the text from left to right or top to down, like this horizontal marquee label or this vertical marquee label.

But since you have asked about something without a timer, a good option is using a WebBrowser control showing a marquee tag, easy and flexible.

You can set any content for that, setup behavior, direction, speed, appearance, width, height and fully customize it.

Example

this.webBrowser1.DocumentText = @"
    <marquee>
    <span style='color:#f00;'>Breaking news: </span>
    Lorem ipsum dolor sit amet, consectetur adipiscing elit.
    </marquee>";
