Process doesn't Start as user when argument are in quotes

process

Process has been behaving oddly and I finally narrowed the symptoms down, but even the documentation has been unhelpful in finding a solution. The class works fine when I don't specify Domain, UserName, and Password -- I can pass Arguments with or without quotes.
But when I specify Domain, UserName, and Password -- it works as long as there are no quoted Arguments, but if any Arguments are quoted the Process doesn't Start (and doesn't seem to fail or throw an Exception or anything).
I have read through the Process and ProcessStartInfo documentation and tried tweaking some properties, but to no avail.

To test and demonstrate the problem I wrote a simple BAT file:

echo %time% > C:\temp\test.out
echo %* >> C:\temp\test.out

And a simple console application to execute it via Process:

namespace Test
{
  public static class Test
  {
    public static void
    Main
    (
      string[] args
    )
    {
      System.IO.File.Delete ( @"C:\temp\test.out" ) ;
    
      System.Diagnostics.Process pr = new System.Diagnostics.Process() ;

      pr.StartInfo.FileName = @"C:\bin\test.bat" ;

      if ( args.Length % 2 == 0 )
      {
        pr.StartInfo.Arguments = @"one two three four" ;
      }
      else
      {
        pr.StartInfo.Arguments = @"one ""two three"" four" ;
      }
      
      System.Console.WriteLine ( pr.StartInfo.Arguments ) ;
      
      pr.StartInfo.UseShellExecute = false ;

      if ( args.Length > 2 )
      {
        pr.StartInfo.Domain = args [ 0 ] ;
        pr.StartInfo.UserName = args [ 1 ] ;         
        
        System.Security.SecureString pwd = new System.Security.SecureString() ;

        foreach ( char c in args [ 2 ] )
        {
          pwd.AppendChar ( c ) ;
        }

        pwd.MakeReadOnly() ;

        pr.StartInfo.Password = pwd ;
      }

      pr.Start() ;
    }
  }
}

So, if you specify Domain, UserName, and Password as parameters it will try to run as that user. If the number of parameters is odd, it will put quotes around a parameter.

After running the app you can examine the contents of the output file (if it exists).

I don't know where else to seek a solution. Has anyone out there run into this and found a solution?


Update: Using CMD.EXE as the Filename and passing /C and the name of the bat file in Arguments seems to work as well, so I'll go with that for now.
