c# - Writing File to Temp Folder

Question

I want to use StreamWriter to write a file to the temp folder.

It might be a different path on each PC, so I tried using %temp%SaveFile.txt but it didn't work.

How can I save to the temp folder, using environmental variables?

And for example, can I use an environmental variable for storing files in %appdata%?

Answer 1

string result = Path.GetTempPath();
