问题 When working with a drive mapped to a Linux share, filenames are case sensitive. PowerShell handles this as expected, but I'd like to sort the output in a manner analogous to the sort order used in the "C" locale, which means sorting by character value in ascending order from U+0000 all the way through U+10FFFF (e.g. '0foo' comes before 'Foo' and 'Foo' comes before 'bar' and 'bar' comes before 'foo') To illustrate the problem: PS > gci Z:\foo | sort -casesensitive xyz Xyz XYZ yZ YZ Output

问题 I'm trying to use Powershell to ping a couple of WCF Webservices from the command line. e.g. I have an WCF Operation [OperationContract] string DoWork(string name); And I can call that with Powershell using. $proxy = New-WebServiceProxy -Uri 'http://localhost/TestService/Service.svc' $proxy.DoWork('Hello World') This works fine as long as the input params and return types are strings. However if I introduce integers, the generated method signatures & return types have additional

问题 What is the default order of result set from Get-ChildItem command in powershell? Is there a order at all or is it just random and would give the results in a different order every time. 回答1: First folders in alphanumeric order (first numbers as [char]). Then files in alphanumeric order (first numbers as [char]). 回答2: There is no guaranteed default sort order. The documentation doesn't state one. The implementation in FileSystemProvider ends up calling DirectoryInfo.GetFiles. The

问题 I'm just curious, do I have any possibility to download the file from SharePoint document library? The problem is that I have like 3-4 files in this library and I need to get the file with the latest modification date.
