Question

I have three paths that I want to be 3 separate arguments passed into an executable. I do startinfo.arguments, but how do I separate these so the executable knows they are three different arguments?

Answer 1

You can simply pass these to the argument property with spaces separating them as you would at the command prompt, enclosing any containing spaces in double quotes.

Update:-

As an example of enclosing spaces in arguments, to copy ‘foo bar baz.txt’ to ‘this is a test.txt’:-

using (var process = new Process
       {
           StartInfo = new ProcessStartInfo
           { 
               FileName = "cmd.exe",
               Arguments = "/c copy \"foo bar baz.txt\" \"this is a test.txt\""
           } 
       })
{
    process.Start();
    process.WaitForExit();
}

The syntax is clumsy, but has the advantage of being consistent with how you would do it at the command line, as pointed out by @Ed S.
