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：

form窗体：

namespace Z_Test{    partial class Form8    {        /// <summary>        /// Required designer variable.        /// </summary>        private System.ComponentModel.IContainer components = null;        /// <summary>        /// Clean up any resources being used.        /// </summary>        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>        protected override void Dispose(bool disposing)        {            if (disposing && (components != null))            {                components.Dispose();            }            base.Dispose(disposing);        }        #region Windows Form Designer generated code        /// <summary>        /// Required method for Designer support - do not modify        /// the contents of this method with the code editor.        /// </summary>        private void InitializeComponent()        {            System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(Form8));            this.richTextBox1 = new System.Windows.Forms.RichTextBox();            this.panel1 = new System.Windows.Forms.Panel();            this.panel1.SuspendLayout();            this.SuspendLayout();            //             // richTextBox1            //             this.richTextBox1.Anchor = ((System.Windows.Forms.AnchorStyles)(((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Left)             | System.Windows.Forms.AnchorStyles.Right)));            this.richTextBox1.BackColor = System.Drawing.SystemColors.InfoText;            this.richTextBox1.ForeColor = System.Drawing.Color.YellowGreen;            this.richTextBox1.Location = new System.Drawing.Point(3, 0);            this.richTextBox1.Name = "richTextBox1";            this.richTextBox1.ScrollBars = System.Windows.Forms.RichTextBoxScrollBars.None;            this.richTextBox1.Size = new System.Drawing.Size(1047, 188);            this.richTextBox1.TabIndex = 2;            this.richTextBox1.Text = resources.GetString("richTextBox1.Text");            this.richTextBox1.ContentsResized += new System.Windows.Forms.ContentsResizedEventHandler(this.richTextBox1_ContentsResized);            //             // panel1            //             this.panel1.BackColor = System.Drawing.SystemColors.InactiveCaption;            this.panel1.Controls.Add(this.richTextBox1);            this.panel1.Dock = System.Windows.Forms.DockStyle.Fill;            this.panel1.Location = new System.Drawing.Point(0, 0);            this.panel1.Name = "panel1";            this.panel1.Size = new System.Drawing.Size(1053, 532);            this.panel1.TabIndex = 4;            //             // Form8            //             this.AutoScaleDimensions = new System.Drawing.SizeF(8F, 15F);            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;            this.ClientSize = new System.Drawing.Size(1053, 532);            this.Controls.Add(this.panel1);            this.Name = "Form8";            this.Text = "Form8";            this.Load += new System.EventHandler(this.Form8_Load);            this.Resize += new System.EventHandler(this.Form8_Resize);            this.panel1.ResumeLayout(false);            this.ResumeLayout(false);        }        #endregion        private System.Windows.Forms.RichTextBox richTextBox1;        private System.Windows.Forms.Panel panel1;    }}

功能代码：

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.IO;using System.Linq;using System.Text;using System.Threading;using System.Threading.Tasks;using System.Windows.Forms;namespace Z_Test{    public partial class Form8 : Form    {        public Form8()        {            InitializeComponent();            initData();            richTextBox1.Location = this.panel1.Location;//设置richTextBox1与外层panel1起始位置一致           // richTextBox1.Width = this.panel1.Width;//设置richTextBox1与外层panel1宽度一直            //richTextBox1.Height = 1500;            //设置richTextBox1的高度，此处需要估算出完全展示完滚动内容的richTextBox1高度            System.Windows.Forms.Timer myTimer = new System.Windows.Forms.Timer();//创建定时器            myTimer.Interval = 50;//间隔时间是以毫秒为单位的            myTimer.Tag = richTextBox1;//该属性用于传递要移动的对象（此处可以不要）            myTimer.Start();//启动定时器                      myTimer.Tick += myTimerTest_Tick;        }        private void myTimerTest_Tick(object sender, EventArgs e)        {            richTextBox1.Top = richTextBox1.Top - 2;//向上移动2            if (richTextBox1.Bottom < 0)            {                richTextBox1.Top = this.Height;                //当richTextBox1底部移动出panel1的上边沿时，保证richTextBox1从panel1下边沿出现            }        }        private void Form8_Load(object sender, EventArgs e)        {                    }        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            }));                 }        private void initData() {            string txtContent = File.ReadAllText(@"D:\Desktop\资本论.txt");            this.richTextBox1.Text = txtContent;        }        private void Form8_Resize(object sender, EventArgs e)        {            //根据不同情况也可以：            if (!this.IsHandleCreated)            {                return;            }            this.richTextBox1.BeginInvoke(new Action(()=>            {                richTextBox1.Width = this.panel1.Width;//设置richTextBox1与外层panel1宽度一直                richTextBox1.Refresh();            }));        }    }}

这里测试使用的Txt大小为4M。
