try
{
string[] input_lines = File.ReadAllLines("C:\\maq\\" + main1.text + "\\" + main1.text + ".txt");
              List<string>  input_lines_list  = input_lines.ToList();
                input_lines_list.RemoveAt(0);
                input_lines_list = input_lines_list.OrderBy((s) => s.Split(',')[0]).ThenByDescending((s) => DateTime.ParseExact(s.Split(',')[1], "yyyyMMdd", null)).ToList();
                int j = 0;
                while (j < input_lines_list.Count - 1)
                {
                    string[] line_detail = input_lines_list[j].Split(',');
                    string[] next_line_detail = input_lines_list[j + 1].Split(',');
                    if (line_detail[2] == line_detail[3] && line_detail[3] == line_detail[4] && line_detail[4] == line_detail[5] && line_detail[5] == input_lines_list[j + 1].Split(',')[5])
                    {
                        input_lines_list.RemoveAt(j);
                        continue;
                    }
                    else if (line_detail[0] == next_line_detail[0] && line_detail[2] == next_line_detail[2] && line_detail[3] == next_line_detail[3] && line_detail[4] == next_line_detail[4] && line_detail[5] == next_line_detail[5])
                    {
                        input_lines_list.RemoveAt(j + 1);
                        continue;
                    }
                    else if (line_detail[0] == next_line_detail[0] && line_detail[1] == next_line_detail[1])
                    {
                        input_lines_list.RemoveAt(j + 1);
                        continue;
                    }
                    j += 1;
                }
          }
          catch(Exception ex)
          {
                  MessageBox.Show(ex.Message);
          }

                input_lines_list.Insert(0, iplut_lines[0])

            File.WriteAllText("C:\\maq\\" + main1.text + "\\" + main1.text + ".txt", "\n");
            System.IO.File.WriteAllLines("C:\\maq\\" + main1.text + "\\" + main1.text + ".txt", input_lines_list);
 }

推荐答案

你不能只关闭它。您需要找出问题的根源并进行排序。有关更多详细信息和一些实用建议，请参阅我之前的回答：使用的文件另一个流程异常 [ ^ ]。

You cannot just close it. You need to find out the root of the problem and sort it out. For further detail and some practical recommendations, please see my past answer: File used by another process exception[^].
