C # - How to get machine information

Question

Using C #, I create a simple application for extracting machine information using the C # code itself.

So far, I have found the following libraries to help get specific information:

• OS, username, machine name ( https://msdn.microsoft.com/en-us/library/system.environment.aspx )
• Network information such as IP address, DNS ( https://msdn.microsoft.com/en-us/library/system.net.dns.aspx )

I still want to figure out how to get the following information:

• CPU temperature
• Laptop / Mobile Battery

Please share with existing .Net libraries or not, and how, please share whether additional hardware, such as software or hardware, is required.

Thank.
