Recently I’ve been wondering how I can suppress the output in my PowerShell scripts when loading assemblies into them. I used to find them useful; but now I find them annoying and they are no substitute for error handling ( I used to find them handy as a way of telling me that the script had got this far in the script).

There is more than one way to suppress output to the console, but for assembly loading, I prefer to use [void] because it looks neater than the alternatives:


What is happening here is that [void] is casting the output into null so it does not appear on the console. Remove the [void] and you will see the output.


I mentioned that I prefer the neatness of this to the alternatives, so what are the alternatives? This post on StackOverflow not only talks about the alternatives, but also performance tests the alternatives against one another. It makes for interesting reading!
