本文实例讲述了C#实现读取注册表监控当前操作系统已安装软件变化的方法。分享给大家供大家参考。具体实现方法如下：

private static HybridDictionary GetSoftName(){ string strSoftName = string.Empty; HybridDictionary hdSoftName = new HybridDictionary(); using (RegistryKey key = Registry.LocalMachine.OpenSubKey(@"Software\Microsoft\Windows\CurrentVersion\Uninstall", false)) { if (key != null) { foreach (string keyName in key.GetSubKeyNames()) { using (RegistryKey key2 = key.OpenSubKey(keyName, false)) { if (key2 != null) { string softwareName = Convert.ToString(key2.GetValue("DisplayName"));//获取DisplayName,如存在值，则系统中安装有该软件 //string installLocation = key2.GetValue("InstallLocation", "").ToString();//软件安装路径 if (!string.IsNullOrEmpty(softwareName)) { if (!hdSoftName.Contains(softwareName)) { hdSoftName.Add(softwareName, string.Empty);//将软件名作为集合的key } } } } } } } return hdSoftName;}

希望本文所述对大家的C#程序设计有所帮助。
