目前我有一个按钮，调用一个函数，有一个10-20秒的处理时间。有没有可能有一些文字像“请等。。。”而不是挂起应用程序。

下面是我调用函数的按钮:

private void btnExec_Click(object sender, EventArgs e)
        {
            LongProcess();
        }

而这就是执行时间过长的函数:

 public void LongProcess()
        {
            DataTable table = new DataTable();

            table.Columns.Add("DateTime", typeof(string));
            table.Columns.Add("Mass1", typeof(string));
            table.Columns.Add("Mass2", typeof(string));
            table.Columns.Add("Mass3", typeof(string));               

            Console.WriteLine(startDate.Value);
            Console.WriteLine(endDate.Value);

            decimal v = decimal.Parse("1.6345e-008", NumberStyles.Float);
            var pattern = @"^""\d+/\d+/\d+ \d+:\d+:\d+ (AM|PM)""\s+-?\d+\s+\d+.?\d+e-\d+";
            var regex = new Regex(pattern, RegexOptions.Compiled);

            string[] filePaths = Directory.GetFiles(@"C:\\test\\", "*.txt");

            var results = new List<string>();

            foreach (var file in filePaths)
            {
                var lines = File.ReadLines(file).Where(x => regex.IsMatch(x));
                results.AddRange(lines);
            }

            foreach (var result in results)
            {
                string[] words = (result.ToString()).Split(' ');
                string date = words[0].Substring(1) + " " + words[1];

                DateTime oDate = DateTime.Parse(date);

                if (oDate >= startDate.Value && oDate <= endDate.Value)
                {
                    string[] words2 = (words[2].ToString()).Split('\t');
                    string m1 = words2[2];
                    string m2 = words2[3];
                    string m3 = words2[4];                           
                    table.Rows.Add(new object[] { oDate.ToString(), m1, m2, m3});

            File.WriteAllText(@"C:\\test.csv", sb.ToString());
            Console.WriteLine("Done Parsing");
        }

任何支持/评论。
