问题 PowerShell has a pretty good built-in help system that I use a lot and I'm able to see all help options with Get-Help * and query Cmdlets or can look up Topics with Get-Help about_* and then say Get-Help about_compar* to open the Comparison Operators topic which is all very good. However, I was trying to find how to get help on the various string operators, like .replace, .compare, .split, .substring. Does anyone know how to pull these topics up on the PowerShell console (possibly, they might

问题 I've been trying to work with an API that only accepts raw text or base64 encoded values in a JSON object. The content I'm POSTing is data from an XML file. So I used Powershell's Get-Content cmdlet (without -Raw ) to retrieve the data from the .xml and then base64 encode it and sent it to the API. The API then decodes it, but the XML formatting was lost. I found a SO post about using the -Raw switch on Get-Content , but it seems like the documentation for this switch is vague. When I used
