进度条小总结

进度更新F2用来控制显示两位小数

 　　　　void UpdateProgress(object sender, ProgressChangedEventArgs e)
        {
            int progress = e.ProgressPercentage;

            lbProgressBar.Content = string.Format("{0:F2}%", ((float)progress/(float)maxValue)*100);

            progressBar1.Value = progress;
        }

将要处理的工作放入另外一个线程

void DoWork(object sender, DoWorkEventArgs e)
        {
            BackgroundWorker bw = sender as BackgroundWorker;
            MainWindow win = e.Argument as MainWindow;

         using (StreamReader sr = new StreamReader(fs, Encoding.Default))
            {
                sr.ReadLine();
                while (!sr.EndOfStream)
                {
                    string line = sr.ReadLine();
                    byte[] byteArray = System.Text.Encoding.Default.GetBytes(line);//还是不准确
                    value += byteArray.Length;
                    string[] data = line.Split('\t');
                    startTelNum = data[0];
                    telType = data[1];
                    telArea = data[2];
                    telType = telType.Replace("\"", "");//去掉字符串里的“”双引号
                    telArea = telArea.Replace("\"", "");
                    SqlHelper.ExecuteNonQuery("insert into T_TelNum(StartTelNum,TelType,TelArea) values(@startTelNum,@telType,@telArea)",
                        new SqlParameter("@startTelNum", startTelNum), new SqlParameter("@telType", telType), new SqlParameter("@telArea", telArea));
                    bw.ReportProgress(value);
                }
            }

可能因为每行最后有很多空格的关系。
