The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

PowerShell and .NET - Calling Methods

Asked by Chris-Dent in MSH/Monad PowerShell, Windows 2003 Server, Microsoft Programming

Tags:


Busily chipping away at understanding PowerShell, but being a complete non-programmer occasionally makes things really odd...

Anyway, perhaps some one already knows this one and I can stop trying to make up reasons.

I really like having access to the .NET Framework, really quite shiny and can do things that were a pain in the proverbial in VbScript. But...

When using classes and their associated methods in the .NET Framework how do you know how to properly call them (in advance, without my usual Trial and Error approach)?

For example, I can call a method in the DNS class like this:

[System.Net.DNS]::GetHostByAddress("<IP>")

And / Or access the values returned with:

([System.Net.DNS]::GetHostByAddress("<IP>")).HostName

All fine so far, but then I go and pick on another class, we'll take Ping this time, sticking in the networking theme. Because it's somewhat consistent I wanted to do this:

[System.Net.NetworkInformation.Ping]::Send("<IP>")

Send being the method under the Ping class that seemed entirely sound. Doesn't work, of course. Instead I have to create an object:

$Ping = New-Object System.Net.NetworkInformation.Ping
$Ping.Send("<IP>")

So, hmmm, anyone happen to know why? If it's not a horribly long answer involving many concepts that I just don't want to get ;)
