## 实现 ##

新建一个Form，设置窗体的背景颜色为黑色，然后再拖拽一个LIstBox用来存取要滚动的内容，再拖拽一个Timer组件

右击Timer组件设置其属性

将Enabled属性设置为true，表示可用，Interval表示执行的时间间隔0.2秒。

然后Timer还有一个Tick事件，表示具体要执行的方法，即每隔0.2秒要执行的操作。

然后设置ListBox的属性和要滚动的内容

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();
            }
