What's the best way to check if the variable is not equal to null in PowerShell?

I have tried the below script

$site = Get-SPWeb -Site "http://mysite"
if($site -ne null)
{
  #MyCode
}

But I get unexpected token null in expression or statement  error

Best answer

You are missing '$' sign before NULL, try to use $null

If($site - nq $null) { #if site variable not equal Null} 

Hope it helps

Check if a variable is not equal to null in PowerShell

Besides @Imran answer, I would like to share another method to check if a variable is equal or not equal to null in PowerShell

Check if a variable is not equal to null

#Metod 1 
if($variable -ne $null)
{
}

#Method 2
if($variable)
{
}

Check if a variable is equal to null

# Metod 1 
if($variable -eq $null)
{
}

#Method 2
if(!$variable)
{
}
