在Unity3d中调用外部程序及批处理文件

如果调用外部普通应用程序, 比如notepad.exe 这样调用

static public bool ExecuteProgram(string exeFilename, string workDir, string args)  
{  
    System.Diagnostics.ProcessStartInfo info = new System.Diagnostics.ProcessStartInfo();  
    info.FileName = exeFilename;  
    info.WorkingDirectory = workDir;  
    info.RedirectStandardOutput = true;  
    info.RedirectStandardError = true;  
    info.Arguments = args;  
    info.UseShellExecute = false;  
    info.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;  
  
    System.Diagnostics.Process task = null;  
  
    bool rt = true;  
  
    try  
    {  
        task = System.Diagnostics.Process.Start(info);  
        if (task != null)  
        {  
            task.WaitForExit(10000);  
        }   
        else  
        {  
            return false;  
        }  
    }   
    catch (Exception e)  
    {  
        Debug.LogError("Error: " + e.ToString());  
        return false;  
    }   
    finally  
    {  
        if (task != null && task.HasExited)  
        {  
            string output = task.StandardError.ReadToEnd();  
            if (output.Length > 0)  
            {  
                Debug.LogError(output);  
            }  
              
            output = task.StandardOutput.ReadToEnd();  
            if (output.Length > 0)  
            {  
                Debug.Log("Error: " + output);  
            }  
              
            rt = (task.ExitCode == 0);  
        }  
    }  
  
    return rt;  
}  

如果需要调用Window的批处理文件BAT, 

或者含有控制台输出的程序, 

或者使用上面的方法卡死, 则使用下面的方法运行

static bool ExecuteProgram(string exeFilename, string workDir, string args)  
{  
    System.Diagnostics.ProcessStartInfo info = new System.Diagnostics.ProcessStartInfo();  
    info.FileName = exeFilename;  
    info.WorkingDirectory = workDir;  
    info.UseShellExecute = true;  
    info.Arguments = args;  
    info.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;  
  
    System.Diagnostics.Process task = null;  
    bool rt = true;  
    try  
    {  
        Debug.Log("ExecuteProgram:" + args);  
          
        task = System.Diagnostics.Process.Start(info);  
        if (task != null)  
        {  
            task.WaitForExit(100000);  
        }  
        else  
        {  
            return false;  
        }  
    }  
    catch (Exception e)  
    {  
        Debug.LogError("ExecuteProgram:" + e.ToString());  
        return false;  
    }   
    finally  
    {  
        if (task != null && task.HasExited)  
        {  
            rt = (task.ExitCode == 0);  
        }  
    }  
  
    return rt;  
}
