Opening a notepad file

I have created a program in C# that takes a few registry keys (Processor Identifier, Vendor Identifier, Bios Status, Bios Date, and System Identifier) and places the information into a command prompt window. What I want to do is place them into a notepad file. How can I go about having the program open notepad and having the information placed in there?

Use StreamWriter class:
