achieve

Create a Form, form background color set to black, and then drag a LIstBox for accessing the contents to be scrolled, and then drag a Timer component

 

 

 

Right-click the Timer component to set its properties

 

 

 

Enabled property set to true, it indicates available, Interval represents the time interval of 0.2 seconds.

Then there is a Timer Tick event, the specific representation to be performed, i.e., every 0.2 seconds to perform the operation.

 

 

Then set the ListBox properties and content to be scrolled

            this.listBox1.BackColor = System.Drawing.SystemColors.WindowText;
            this.listBox1.BorderStyle = System.Windows.Forms.BorderStyle.None;
            this.listBox1.ForeColor = System.Drawing.SystemColors.InactiveCaption;
            this.listBox1.FormattingEnabled = true;
            this.listBox1.ItemHeight = 12;
            this.listBox1.Items.AddRange(new object[] {
            "逆战",
            "演唱：张杰",
            "在这个风起云涌的战场上",
            "暴风少年登场",
            "在战胜烈火重重的咆哮声",
            "喧闹整个世界",
            "硝烟狂飞的讯号",
            "机甲时代正来到",
            "热血逆流而上",
            "战车在发烫",
            "勇士也势不可挡",
            "come on逆战 逆战来也",
            "王牌要狂野",
            "闯荡宇宙摆平世界",
            "Oh 逆战 逆战狂野",
            "在这个风起云涌的战场上",
            "暴风少年登场",
            "在战胜烈火重重的咆哮声",
            "喧闹整个世界",
            "硝烟狂飞的讯号",
            "机甲时代正来到",
            "热血逆流而上",
            "战车在发烫",
            "勇士也势不可挡",
            "come on逆战 逆战来也",
            "王牌要狂野",
            "闯荡宇宙摆平世界",
            "Oh 逆战 逆战狂野"
           });
            this.listBox1.Location = new System.Drawing.Point(56, 377);
            this.listBox1.Name = "listBox1";
            this.listBox1.Size = new System.Drawing.Size(400, 480);
            this.listBox1.TabIndex = 0;

 

然后在窗体的Load事件中，将ListBox置于窗体最底部，即设置其距离顶部的距离为窗体的高度。

然后再上面设置的每隔0.2秒执行的方法中进行判断，如果ListBox距离顶部的位置小于负的自己的高度，即一次轮播到顶，再重新设置其距离顶部的距离为窗体高度，否则就会将ListBox举例顶部的距离减去5。

关键代码

       private void Form1_Load(object sender, EventArgs e)
        {
            listBox1.Top = this.Height;
            this.Focus();
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            if (listBox1.Top < -listBox1.Height)
            {
                listBox1.Top = this.Height;
            }
            listBox1.Top = listBox1.Top - 5;
            this.Focus();
        }
