The Environment.GetEnvironmentVariables property returns the list of all the environment variables, as an IDictionary object. If you want to display them sorted by their name, as the SET command does at the prompt, you need the following tricky code:

' Get all the variables, as an IDictionary objectDim vars As IDictionary = Environment.GetEnvironmentVariables' moves all the keys into an arrayDim keys(vars.Count - 1) As Objectvars.Keys.CopyTo(keys, 0)' sort the Keys arrayArray.Sort(keys)' display all environment variables, sorted by keysDim key As StringFor Each key In keys    Console.WriteLine("{0}={1}", key, vars(key))Next
