Process.Start() and PATH environment variable

by

Not quite sure why the problem occurs. Though, I can think of one solution that works on my machine:

var enviromentPath = System.Environment.GetEnvironmentVariable("PATH");

Console.WriteLine(enviromentPath);
var paths = enviromentPath.Split(';');
var exePath = paths.Select(x => Path.Combine(x, "mongo.exe"))
                   .Where(x => File.Exists(x))
                   .FirstOrDefault();

Console.WriteLine(exePath);

if (string.IsNullOrWhiteSpace(exePath) == false)
{
    Process.Start(exePath);
}

I did find one para which gave me the idea for this solution. From the documentation for Process.Start

If you have a path variable declared in your system using quotes, you
must fully qualify that path when starting any process found in that
location. Otherwise, the system will not find the path. For example,
if c:\mypath is not in your path, and you add it using quotation
marks: path = %path%;”c:\mypath”, you must fully qualify any process
in c:\mypath when starting it.

The way I read it, even though the PATH variable contained a valid path that Windows is able to use, Process.Start is unable to use it and needs the fully qualified path .
