在段落中获取特定文本[关闭]

Question

您好，我正在使用这个 c# windows 窗体 我想在（嗯）之前得到这个数字 有时会超过 50 个数据。

示例格式：

19/09/27    9:17:37
SOT404 Sn_Ni LEADSr.rtn
1
Batch no.      1
Date / Shift:  19-09-27A
User Name:     OLIVER
[DATA]

       1 Sn                 10.259(um)  
       2 Sn                 10.965(um)  
       3 Sn                 10.921(um)  
       4 Sn                  9.690(um)  
       5 Sn                  9.774(um)  
       6 Sn                 10.312(um)  

                Mean            Std. dev.       Range
Sn                10.320          0.5433           1.275
                Max.            Min.            Cpk
Sn                10.965           9.690         2.04
                UCL             LCL
Sn                15.000           7.000

预期输出：

 10.259
 10.965
 10.921
 9.690
 9.774
 10.312

我现在只是将它存储在数组中，不知道下一步。

 private void FormatRawData_2(string rawData)
        {
            string[] data = Regex.Split(rawData, "\r\n");
            if (rawData.Contains("[DATA]"))
            {
                int index = Array.IndexOf(data, "[DATA]");
            }
            else {
                MessageBox.Show("Received data is not complete");
            }
        }

更新我的代码： 笔记： Config.DataColumn 的值等于 3

 private void FormatRawData_2(string rawData)
        {

            string[] data = Regex.Split(rawData, "\r\n");
            if (rawData.Contains("[DATA]"))
            {
                int index = Array.IndexOf(data, "[DATA]");
                //int markIndex = Array.IndexOf(data, "");
                for (int ctr = index + 1; ctr < data.Length;ctr++ ) 
                {
                    string[] lineData = Regex.Split(data[ctr], @"[\s+\t\n]");


                  int dataCtr = 1;
                  for (int lineCtr = 0; lineCtr < lineData.Length - 1; lineCtr++)
                  {
                      if (lineData[lineCtr] != string.Empty)
                      {
                          if (dataCtr == Config.DataColumn)
                          {
                              SetTextProcessed(lineData[lineCtr]);
                              break;
                          }
                          dataCtr++;
                      }
                  }

                }


            }
            else {

            }
        }

现在得到结果：

10.259(um)
10.965(um)
10.921(um)
9.690(um)
9.774(um)
10.312(um)
dev.
0.5433
9.690

已经很接近了。

你可以试试这个：

using System.IO;
using System.Collections.Generic;

static void Test()
{
  var lines = File.ReadAllLines(@"c:\\sample.txt");
  var dataUM = new List<string>();
  var dataColumn1 = new List<string>();
  var dataColumn2 = new List<string>();
  var dataColumn3 = new List<string>();
  int indexEndColumn1 = 24;
  int indexEndColumn2 = 40;
  int indexEndColumn3 = 0; /* data provided by OP are not aligned */
  Action<string, int, List<string>> extractData = (str, end, list) =>
  {
    int indexStart = -1;
    for ( int index = end - 1; index >= 0; index-- )
      if ( str[index] == ' ' )
      {
        indexStart = index;
        break;
      }
    if ( indexStart != -1 )
      list.Add(str.Substring(indexStart + 1, end - 1 - indexStart));
  };
  foreach ( string line in lines )
  {
    int indexEnd = line.IndexOf("(um)");
    if ( indexEnd != -1 )
      extractData(line, indexEnd, dataUM);
    else
    if ( line.StartsWith("Sn") )
    {
      extractData(line, indexEndColumn1, dataColumn1);
      extractData(line, indexEndColumn2, dataColumn2);
      extractData(line, indexEndColumn3, dataColumn3);
    }
  }
  Action<string, List<string>> printData = (title, list) =>
  {
    Console.WriteLine(title);
    foreach ( var item in list )
      Console.WriteLine(item);
    Console.WriteLine();
  };
  printData("Data content for (um)", dataUM);
  printData("Data content for Column 1", dataColumn1);
  printData("Data content for Column 2", dataColumn2);
  printData("Data content for Column 3", dataColumn3);
}

它输出：

Data content for (um)
10.259
10.965
10.921
9.690
9.774
10.312

Data content for Column 1
10.320
10.965
15.000

Data content for Column 2
0.5433
9.690
7.000

Data content for Column 3

Answer 2

这是我为获得预期结果所做的工作，请告诉我你在我的回答中看到的复杂情况 Config.DataColumn 等于 3

 private void FormatRawData_2(string rawData)
        {

            string[] data = Regex.Split(rawData, "\r\n");
            if (rawData.Contains(@Config.DataPart))
            {
                int index = Array.IndexOf(data, @Config.DataPart);

                for (int ctr = index + @Config.RowDataStart; ctr < data.Length; ctr++)
                {
                    string[] lineData = Regex.Split(data[ctr], @"[\s+\t\n]");

                    int dataCtr = 1;

                    for (int lineCtr = 0; lineCtr < lineData.Length; lineCtr++)
                    {
                        if (lineData[lineCtr] != string.Empty)
                        {

                            if (dataCtr == Config.DataColumn)
                            {
                                if (lineData[lineCtr].Contains(")"))
                                {
                                    SetTextProcessed(lineData[lineCtr].Remove(lineData[lineCtr].Length - 4));
                                    break;
                                }
                            }
                            dataCtr++;
                        }

                    }

                }

            }
            else
            {
                MessageBox.Show("Received data is not complete");
            }
        }
