Running a process and the environment path variable

[Clive Dixon]

If I do

System.Diagnostics.Process p = new System.Diagnostics.Process;

p.StartInfo.FileName = "<an executable name>";

// ... (set other properties)

p.Start();

How can I force .NET to look for the named executable in the path? It does
not appear to do this by default.

By default it ignores the environment variable Path. You need to pad it while
you pass a file name.

e.g.
myProcess.Start(Environment.GetFolderPath(Environment.SpecialFolder.Personal) + "MyUtility.exe")

Optionally you can set WorkingDirectory on StartInfo (which is an instance
of ProcessStartInfo).

What I am doing with the product we're developing is to define an environment
variable e.g. set MyRoot=C:\MyProduct and then (because all the executables
are in the bin directory I use "%MyRoot%\bin\whatever.exe" and when I set
the Process I pass the name through
System.Environment.ExpandEnvironmentVariables()
