Powershell 脚本导出-Csv 怪异

Question

我创建了一个小脚本来提取文件夹及其子文件夹的指定字符串的所有行。 在我想将这些行导出到 excel (csv) 之前，它的行为与预期一致。 那时它只导出两行（至少每次都是相同的两行）。 实际上，它应该有大约 40 行的 exportet。 工作脚本如下所示：

[string]$pathSource = "D:\Projects\test"
[string]$pathTarget = "D:\Projects\test\searchpattern-sql.csv"

[string[]]$excludeFileTypes = "*.dll","*.pdb","*.gif","*.dat","*.bin","*.msi","*.epi4","*.png","*.tlog","*.gif","*.cache","*.csproj","*.config","*.user","*.txt"

[string]$searchPattern = "sqlCommand"

Get-ChildItem $pathSource -Exclude $excludeFileTypes  -Recurse | Select-String $searchPattern | Sort-Object Path | Select-Object Path, LineNumber, Line

使用导出 cmdlet (| Export-Csv -path $pathTarget) 添加新的 pipe 会以某种方式破坏搜索。 我究竟做错了什么？

Answer 1

只需测试一下：

[string]$pathSource = "D:\Projects\test"
[string]$pathTarget = "D:\Projects\test\searchpattern-sql.csv"

[string[]]$excludeFileTypes = "*.dll","*.pdb","*.gif","*.dat","*.bin","*.msi","*.epi4","*.png","*.tlog","*.gif","*.cache","*.csproj","*.config","*.user","*.txt"

[string]$searchPattern = "sqlCommand"

$a = Get-ChildItem $pathSource -Exclude $excludeFileTypes  -Recurse | Select-String $searchPattern | Sort-Object Path | Select-Object Path, LineNumber, Line
$a | Export-Csv yourfile.csv -NoTypeInformation

$a var 只包含我导出的行数组。

就个人而言，我发现使用Export-CSV存在问题。 我发现工作正常的是 pipe 到ConvrtTo-CSV ，然后到Set-Content或 output 到文件使用重定向。
