You need to load the `System.Web` assembly. Use the `Add-Type` cmdlet like so,

```
PS C:\> [System.Web.HttpUtility]::UrlEncode("www.google.com")
Unable to find type [System.Web.HttpUtility].

PS C:\> Add-Type -AssemblyName System.Web
PS C:\> [System.Web.HttpUtility]::UrlEncode("www.google.com")
www.google.com

```
