从文本文件中搜索文本框中的每个单词并添加到数据表

Question

我需要从文本文件列表中搜索单词，并且每个单词在文本框中用空格或分号分隔。将行添加到数据表并将其显示到数据网格。问题只是表格中显示的最后一个字。提前致谢。

Sub test(ByVal strtofind As String) 
    Dim tmp2Table As DataTable = New DataTable 

    tmp2Table.Columns.Add("SN", GetType(String)) 
    tmp2Table.Columns.Add("Dataset", GetType(String)) 
    tmp2Table.Columns.Add("Param", GetType(String)) 
    tmp2Table.Columns.Add("Value", GetType(String)) 

    Dim strTemp() As String 
    Dim lines() As String 
    Dim strline As String = "" 

    Dim fileList = Directory.GetFiles("C:\Users\sterc\Desktop\Traceview\Complete\", "*.txt", False) 
    Dim sb = New StringBuilder() 
    Dim result As String = String.Empty 
    Dim value As String = String.Empty 
    Dim s As String = txtParamSearch.Text 
    Dim str As String = "" 
    Dim strdataset As String = "" 
    Dim strParam As String = "" 
    Dim strParamResult As String = "" 
    Dim strSN As String = "" 

    For Each fileName In fileList 
     lines = File.ReadAllLines(fileName) 
     Dim intTotalLines As Integer = lines.Length 
     ' Split string based on spaces. 
     For intCounter = 1 To intTotalLines - 1 
      strline = lines(intCounter) 
      If (Regex.IsMatch(strline, "----- Test_") And Regex.IsMatch(strline, ", Started At ")) Then 

       strTemp = strline.Split(" ") 
       strdataset = strTemp(3).TrimEnd(",") 
      End If 
      If Regex.IsMatch(strline, "Reported module serial number:") Then 
       strTemp = Regex.Split(strline, ": ") 
       strSN = strTemp(1) 
      End If 
      Dim strParamtofind As String = "\b" & strtofind & "\b\s+(\w+)" 

      For Each a As Match In Regex.Matches(strline, strParamtofind, RegexOptions.IgnoreCase) 

       tmp2Table.Rows.Add(strSN, strdataset, a.Groups(0).Value, a.Groups(1).Value) 

      Next 

     Next 

    Next 
    DataGridView1.DataSource = tmp2Table 

End Sub

Sub strArr() 

    Dim s As String = txtParamSearch.Text 
    Dim str As String = "" 

    Dim words As String() = s.Split(New [Char]() {";"c}) 

    Dim word As String 
    For Each word In words 
     test(word) 
    Next 

End Sub 

另一件事是显示整个号码或四舍五入。假设像下图。（带小数点）

我需要从一个文本文件中搜索数据/秒，每个文件都包含以下行。然后在它下面是我可能列在文本框中查找的数据。 让我们来看看我需要找到的文本框，

• SOA_MinCurrent_EDATA;
• Isoa_OPSL_initial

每个列出的两个的，将搜索一个文件夹下的每个文本文件。然后逐行显示它们。就像上面的截图一样。问题是只显示字符串搜索和数字四舍五入。

Answer 1

我有点困惑在这里，如果你提供更多信息，我可以帮你。

您有多个文件，其中一些文件用空格拆分每个列的值，并且在文件内没有任何分号，另一些文件用分号拆分每列的值，并且文件中没有空格正确？

如果前面的问题是真实的，文件中的每一行包含的信息，将填补每一行，然后我会用：

Dim r as StreamReader as New StreamReader(FilePath) 
Dim Line as String 

Do While StreamReader.Peek() > -1 //Go through the file until EOF 

Line = r.readline() //Read the line and put it into Line 
If InStr(Line, " ") Then //Search for spaces inside Line 
//This file is separated by spaces, put the code to add to the table. 
Else If InStr(Line, ";") Then //search for semicolons inside line. 
//This file is separated by semicolons, put the code to add to the table. 
End If 

Loop 

我希望这有助于。如果没有，请给我们提供一些细节。
