遇到一个需求，替换某目录下每个文件中指定的多个字符串，用powershell解决

$fileList = Get-ChildItem  'N:\ps\ClassLibrary\' -recurse *.cs | %{$_.FullName}
Foreach($file in $fileList)
{
    (Get-Content $file) |
	Foreach-Object {
		$_ -replace 'bdOrderinfo_save','Orderinfo_save'-replace bdOrderinfo_sel','Orderinfo_sel'

		}  |
	Out-File $file

}
