.net利用本地播放器播放视频文件代码

前台点击按钮，执行js事件，跳转到后台代码：

function funShowVideo(index) {
            var iTop = (window.screen.availHeight - 30 - 500) / 2; //获得窗口的垂直位置;
            var iLeft = (window.screen.availWidth - 10 - 660) / 2; //获得窗口的水平位置;
            window.open("ShowVideo.aspx?ShowType=" + index, "newwindow1", "width=660px,height=500px,top=" + iTop + ",left=" + iLeft + ",toolbar=no,menubar=no,scrollbars=yes,resizable=yes,location=no,status=no");
        }

后台接收前台传过来的参数，并执行相应代码：

if (Request.QueryString["ShowType"] != null)
                    {
                        string strType = Request.QueryString["ShowType"].ToString();
                        string strVideoPath = AppDomain.CurrentDomain.BaseDirectory + "Videos\\";//视频路径

\\ AppDomain.CurrentDomain.BaseDirectory：获取当前路径
                        string strVideoName = "";   //视频名称
                        string strNodeName = "";
                        if (strType == "1")
                        {
                            strNodeName = "CleanVideo";
                        }
                        else if (strType == "2")
                        {
                            strNodeName = "AjustVideo";
                        }
                        else if (strType == "3")
                        {
                            strNodeName = "ChangeVideo";
                        }
                        if (System.Configuration.ConfigurationManager.AppSettings[strNodeName] != null)
                        {
                            strVideoName = System.Configuration.ConfigurationManager.AppSettings[strNodeName].ToString();
                            strVideoPath += strVideoName;
                            if (File.Exists(strVideoPath))
                            {
                                Label2.Text = PlayMedia(strVideoPath);
                            }
                        }
                    }

//播放视频文件的代码
