最新在做一个播放投屏的功能。
主要是播放投屏TXT内容,进行滚动播放。
下面先看下效果:

完成后效果图
过程1. 首先界面创建一个panel 一个rickbox
        private System.Windows.Forms.RichTextBox richTextBox1;
        private System.Windows.Forms.Panel panel1;
    
设置panel1 的dock 为fill 设置panel在主窗体里。停靠在主窗体里。
this.panel1.Dock = System.Windows.Forms.DockStyle.Fill;
设置richtexbox anchor 上、 左、右 注意这里不要设置dock 为fill
this.richTextBox1.Anchor = ((System.Windows.Forms.AnchorStyles)(((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Left) 
            | System.Windows.Forms.AnchorStyles.Right)));
    
设置richtextbox的背景色和文字颜色:
   this.richTextBox1.BackColor = System.Drawing.SystemColors.InfoText;
            this.richTextBox1.ForeColor = System.Drawing.Color.YellowGreen;
    
设置的ContentsResized 事件
 private void richTextBox1_ContentsResized(object sender  ContentsResizedEventArgs e)
        {
            //根据不同情况也可以:
            if (!this.IsHandleCreated)
            {
                return;
            }
            this.richTextBox1.BeginInvoke(new Action(() =>
            {
                richTextBox1.Height = e.NewRectangle.Height   10;
                richTextBox1.Width = this.panel1.Width;//设置richTextBox1与外层panel1宽度一直
            }));
         
        }
    

下面放一下全部代码:
