c#獲取安裝的軟件和路徑（注冊表）

獲取安裝軟件和路徑，通過注冊表得到。實例代碼：

 using (RegistryKey key = Registry.LocalMachine.OpenSubKey(@"SoftwareMicrosoftWindowsCurrentVersionUninstall", false))
            {
                if (key != null)//判斷對象存在
                {
                    foreach (string keyName in key.GetSubKeyNames())//遍歷子項名稱的字符串數組
                    {
                        using (RegistryKey key2 = key.OpenSubKey(keyName, false))//遍歷子項節點
                        {
                            if (key2 != null)
                            {
                                string softwareName = key2.GetValue("DisplayName", "").ToString();//獲取軟件名
                                string installLocation = key2.GetValue("InstallLocation", "").ToString();//獲取安裝路徑
                                if (!string.IsNullOrEmpty(installLocation))
                                {
                                    //將信息添加到ListView控件中
                                    ListViewItem item = new ListViewItem(softwareName);
                                    item.SubItems.Add(installLocation);
                                    listView1.Items.Add(item);
                                }
                            }
                        }
                    }
                }
            }

        }
