Counter for dynamic variable name

Question

Hi,

How can this be achieved. I have string values passed to a parameter of a function, and as you can see the allowable values match the start of the variable counters. So instead of this:

switch( $Result ) {
    "Info"    { $Script:InfoMsgCount++ }
    "Success" { $Script:SuccessMsgCount++ }
    "Warning" { $Script:WarningMsgCount++ }
    "Error"   { $Script:ErrorMsgCount++ }
} 

do this:

if( $Result -ne "Default ) { $ResultMsgCount++ }

Answer 1

Try this.

if( $Result -ne "Default" ) { Invoke-Expression ('$script:' + $Result + "MsgCount++")  }
