学生时代做的一个非常低级的卡拉OK播放器

学生时代做的一个非常低级的C#卡拉OK播放器。
实现了桌面卡拉OK[单行，双行]，繁简转换，歌曲搜索，3种播放模式[单首，循环，随机]，全屏歌词，全局快捷键，XML配置，指定歌词文件夹，等等一些简单的功能。

无意中翻出来了，看看，听听歌，有别有一番乐趣，想当初做这个的时候才接触编程1年。里面用了太多的集合，歌词判断也非常不准备。呵呵。算是用一种非常笨的方法实现的吧。里面没什么高深的技术。主要就是用到了双缓冲[一种防止歌词刷新时屏幕闪烁的技术]、注册全局快捷键等。
已经好久没有接触C#了，虽然这是曾经非常感兴趣的东西，却为了学习编程思想选择了JAVA。如果现在再让我做，我一定会把里面的代码简化简化再简化吧。看着那些乱七八糟的代码，想想自己当年的何其的菜鸟水平的作品。也是一种人生的乐趣。

桌面卡拉OK显示[支持单行，双行]：
配置：
歌词配置[当时我还没有学XML，实现来源于网上]：
<configuration><appSettings><add key="lrcDir" value="E:\music\AIRPLAY.DAT\Lyrics" /><add key="playState" value="2" /><add key="sound" value="28" /><add key="DeskIsDoubleline" value="true" /><add key="DeskFontFamily" value="英章楷书" /><add key="DeskFontSize" value="27.75" /><add key="DeskFontStyle" value="bold" /><add key="DeskNormalColor" value="-65536" /><add key="DeskLightColor" value="-16711936" /><add key="FontSize" value="15" /><add key="NormalColor" value="-4144960" /><add key="LightColor" value="-16711872" /><add key="BackColor" value="-16777216" /><add key="FontStyle" value="bold" /><add key="FontFamily" value="英章楷书" /><add key="DeskBackColor" value="-16777216" /></appSettings>
</configuration>读取配置文件的核心处理类：
using System;
using System.Collections.Generic;
using System.Text;
using System.Xml;namespace LrcCollection
{internal class Config{public static string GetValue(string AppKey){try{XmlDocument document = new XmlDocument();document.Load(System.AppDomain.CurrentDomain.BaseDirectory + "LrcSet.xml");XmlElement element = (XmlElement)document.SelectSingleNode("//appSettings").SelectSingleNode("//add[@key='" + AppKey + "']");if (element != null){return element.GetAttribute("value");}return null;}catch{return null;}}public static void SetValue(string AppKey, string AppValue){try{XmlDocument document = new XmlDocument();document.Load(System.AppDomain.CurrentDomain.BaseDirectory + "LrcSet.xml");XmlNode node = document.SelectSingleNode("//appSettings");XmlElement element = (XmlElement)node.SelectSingleNode("//add[@key='" + AppKey + "']");if (element != null){element.SetAttribute("value", AppValue);}else{XmlElement newChild = document.CreateElement("add");newChild.SetAttribute("key", AppKey);newChild.SetAttribute("value", AppValue);node.AppendChild(newChild);}document.Save(System.AppDomain.CurrentDomain.BaseDirectory + "LrcSet.xml");}catch{SetValue(AppKey, AppValue, true);}}public static void SetValue(string AppKey, string AppValue, bool tt){XmlDocument document = new XmlDocument();XmlNode node = document.CreateNode(XmlNodeType.Element, "configuration", "");document.AppendChild(node);XmlNode node2 = document.CreateNode(XmlNodeType.Element, "appSettings", "");node.AppendChild(node2);XmlElement newChild = document.CreateElement("add");newChild.SetAttribute("key", AppKey);newChild.SetAttribute("value", AppValue);node2.AppendChild(newChild);document.Save(System.AppDomain.CurrentDomain.BaseDirectory + "LrcSet.xml");}}
}
下面是画歌词的处理类[现在自己都看不懂当初是如何实现的了，贴在这里吧。]:
说一说主要的思想：
画歌词的面板一定要继承UserControl类，然后重写其protected override void OnPaint(PaintEventArgs pe)方法，实现双缓冲，在这里面画歌词。
画卡拉OK歌词的原理是：先画背景[底层]，再画你要显示的所有歌词[中间层]，每行歌词都是顺序向下的，中间有间距，然后再你画好的歌词上面，画卡拉OK歌词，也就是高亮显示的那一行歌词[最上层]，这一行歌词会覆盖之前画的中间层歌词的那一行，当然这样它还不是卡拉OK显示的，卡拉OK显示就要取出当前这句歌词和下一句歌词之间的时间，然后从左至右，匀速的画上高亮显示的这一行，看起来就是卡拉OK显示出来了。像酷狗这种歌词是经过精准处理的。
桌面歌词就很简单了，主要是一个无标题的窗体，做上鼠标移动事件即可拖动，单行，双行歌词也只不过是多了一层判断。双行就是每次唱完一句就取出下一句画在面板上。单行就是唱一句画一句。

如何读取：
如果你眼睛好，你会发现这里面还有2个方法
1个是用记事本打开歌词的，1个是定位文件[给一个路经它，它会自动在电脑上帮你定位这个文件]的。前者可能简单，但后者却更实用。
实现方法分别为：
System.Diagnostics.Process.Start("NOTEPAD.EXE", 文本的路径);
System.Diagnostics.Process.Start("explorer.exe", "/select," + 文本的路径);
