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();
         }
         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 > )
             {
                 Debug.LogError(output);
             }  

             output = task.StandardOutput.ReadToEnd();
             if (output.Length > )
             {
                 Debug.Log("Error: " + output);
             }  

             rt = (task.ExitCode == );
         }
     }  

     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();
         }
         else
         {
             return false;
         }
     }
     catch (Exception e)
     {
         Debug.LogError("ExecuteProgram:" + e.ToString());
         return false;
     }
     finally
     {
         if (task != null && task.HasExited)
         {
             rt = (task.ExitCode == );
         }
     }  

     return rt;
 }
