I often notice that they use search paths in different ways, but how do they differ (that is, work for different operating systems in some different way or what)?

What's the difference between

string environmentVariable = Environment.GetEnvironmentVariable("temp");

or simply

 string environmentVariable = Path.GetTempPath();

Environment.GetEnvironmentVariable("temp") will simply return the value of the environment variable named temp

Path.GetTempPath will return the first existing value from the following list:

  1. The path specified in the TMP environment variable.
  2. The path specified in the TEMP environment variable.
  3. The path specified in the USERPROFILE environment variable.
  4. Windows directory.

... so it is safer and safer than calling GetEnvironmentVariable("temp") .

By the way, this is directly stated in MSDN using the Path.GetTempPath method Path.GetTempPath
