How to add multiple values in the Hashtable using PowerShell?
Example
For example, we have a below-created hashtable.
PS C:\> $servicehash = @{Name='Spooler';State='Stopped';StartType='Automatic'} PS C:\> $servicehash
Output
Name Value ---- ----- Name Spooler StartType Automatic State Stopped
We need to add multiple values to the Name Key. If we directly append the value to the key it will treat it as a string and we will not get the desired output. See the example below.
Example
PS C:\> $servicehash.Name += "Winrm" PS C:\> $servicehash
Output
Name Value ---- ----- Name SpoolerWinrm StartType Automatic State Stopped
So to add the multiple values, we first need to declare a key as an array but by doing so it will clear the previous value so we have to add the previous value as well to the array.
Example
PS C:\> $servicehash.Name = @() PS C:\> $servicehash.Name += "Spooler" PS C:\> $servicehash.Name += "Winrm" PS C:\> $servicehash
Output
Name Value ---- ----- Name {Spooler, Winrm} StartType Automatic State Stopped
PS C:\> $servicehash.Name Spooler Winrm
