Unity中使用c# Process在Mac上异常Win32Exception:

http://blog.dou.li/Process-Mac-Win32Exception.html

在Unity中调用TexturePacker打包图集，核心代码如下：

    Process p = new Process ();
    p.StartInfo.FileName = "TexturePacker";
    p.StartInfo.CreateNoWindow = true;
    p.StartInfo.UseShellExecute = false;
    p.StartInfo.RedirectStandardError = true;
    p.StartInfo.RedirectStandardOutput = true;
    p.Start();
    p.WaitForExit();

在Windows上运行正常，Mac上报异常：

Win32Exception: ApplicationName='TexturePacker', CommandLine='',
CurrentDirectory='' System.Diagnostics.Process.Start_noshell
(System.Diagnostics.ProcessStartInfo startInfo,
System.Diagnostics.Process process)
System.Diagnostics.Process.Start_common
(System.Diagnostics.ProcessStartInfo startInfo,
System.Diagnostics.Process process) System.Diagnostics.Process.Start
() (wrapper remoting-invoke-with-check)
System.Diagnostics.Process:Start ()

一番查找发现，Mac上应该用open命令调用目标应用，Mac版本的代码修改如下：

    Process p = new Process ();
    p.StartInfo.FileName = "open";
    p.StartInfo.Arguments = "-a TexturePacker -n --args xxx";
    p.StartInfo.CreateNoWindow = true;
    p.StartInfo.UseShellExecute = false;
    p.StartInfo.RedirectStandardError = true;
    p.StartInfo.RedirectStandardOutput = true;
    p.Start();
    p.WaitForExit();

-n 启动新的TexturePacker实例
--args 后面跟TexturePacker需要的参数
