上下文输出到 CSV 文件

Question

I need to search 10-15 strings into the entire application codes(more than 10000 programs) so I have inserted the strings that i need to search in a text file "strings.text". I also need to know the previous and next line of the matched string line so I am using "Context 1" in the below script. However, the below script is giving output as only Matched String line.

$content = Get-Content strings.txt
ForEach ($Word in $content){
  Get-ChildItem -recurse |
    Select-String -pattern $Word -Context 1 |
    Select-  path,line,linenumber,filename |
    Export-csv -Path "\result_$word.csv"
}

Output:

Path                Line          LineNumber   FileName
desktop\prog1.txt   Server(xyz)   3            prog1.txt
desktop\prog2.txt   Server(xyz)   6            prog2.txt

What I really want is:

Path                Line          LineNumber   FileName
                    Connect       2            prog1.txt
desktop\prog1.txt   Server(xyz)   3            prog1.txt
                    stop          4            prog1.txt

                    Connect       8            prog2.txt
desktop\prog2.txt   Server(xyz)   9            prog2.txt
                    stop          10           prog2.txt

Can anyone please help how can I get this output? Please suggest if there is any other way to get the required output.

If you want to export to a CSV you need to create separate objects for each CSV line. Try something like this:

foreach ($Word in $content){
  Get-ChildItem -Recurse |
    Select-String -Pattern $Word -Context 1 |
    ForEach-Object {
      New-Object -Type PSCustomObject -Property @{
        Path       = ''
        Line       = $_.Context.PreContext[-1]
        LineNumber = $_.LineNumber - 1
        Filename   = $_.FileName
      }
      New-Object -Type PSCustomObject -Property @{
        Path       = $_.Path
        Line       = $_.Line
        LineNumber = $_.LineNumber
        Filename   = $_.FileName
      }
      New-Object -Type PSCustomObject -Property @{
        Path       = ''
        Line       = $_.Context.PostContext[0]
        LineNumber = $_.LineNumber + 1
        Filename   = $_.FileName
      }
    } | Export-Csv -Path "\result_$word.csv" -NoType
}

$_.Context.PreContext[-1] is the last line of the pre-context, $_.Context.PostContext[0] is the first line of the post-context.
