Vista Tutorial - Error: "Cannot convert "System.Object[]" to "System.Int32"."

Your for loop syntax is incorrect:

Replace commas with semicolons

for ($i=0; $i -lt $NoOfComputers; $i++) ..

1) I created this script:

[string[]]$Computers = "Server1", "Server2", "Server3", "Server4",
"Server5", "Server6", "Server7", "Server8", "Server9"
[int]$NoOfComputers = $Computers.length
$NoOfComputers.gettype()
[int32]$i = 0
$I.gettype()
if ($args.length -gt 1) {
"I am copying "+$args[0]+" to PC:"
if (Test-Path $args[0]) {
for ($i=0, $i -lt $NoOfComputers, $i++) {
$Computers[$I]
Copy-Item $args[0] "\\$Computers[$I]\$Args[1]"
}
}
}


2) I run it:
PS C:\Aplikace\CCV> .\CopyToAllPc.ps1 WakeOnLAN.bat C$\Aplikace\CCV

3) It shows this error:

IsPublic IsSerial Name BaseType
-------- -------- ---- --------
True True Int32 System.ValueType
True True Int32 System.ValueType
I am copying WakeOnLAN.bat to PC:
The '-lt' operator failed: Could not compare "0" to "System.Object[]".
Error: "Cannot convert "System.Object[]" to "Sys
tem.Int32".".
At C:\Aplikace\CCV\CopyToAllPc.ps1:31 char:22
+ for ($i=0, $i -lt <<<< $NoOfComputers, $i++) {

4) Please, where is problem?

This won't work either:

Copy-Item $args[0] "\\$Computers[$I]\$Args[1]"


You need to put each expression in a subexpression notation if you want it
to be expanded inside a string:

Copy-Item $args[0] "\\$($Computers[$I])\$($Args[1])"
