我从未编写过应用程序，因此我将发布整个代码（80 行）。（我来自编写脚本的背景。）

我的目标是加载或创建“已使用”端口列表，选择不在列表中的范围内的数字，如果尝试到达未使用端口的次数达到 129，则运行 Windows 批处理文件.

这也会将所选端口转换为 .cmd

（其中一些是来自 SO 的来源的合并）

            {
                string[] values = sr.ReadToEnd().Split(';');
                for(int i = 0; i < values.Length; i++)
                {
                    int.TryParse(values[i], out usedPorts[i]);
                }
            }
        }
        public static void Write()
        {
            File.AppendAllText(@"C:\Users\Administrator\Desktop\TerrariaServer\filebin\activeports.txt", "set port="+chosenPort+";");
            File.Move(@"C:\Users\Administrator\Desktop\TerrariaServer\filebin\activeports.txt", Path.ChangeExtension(@"C:\Users\Administrator\Desktop\TerrariaServer\filebin\activeports.txt", ".cmd"));
        }
    }
}

我在最终导出方面还有一些工作要做（比如删除“;”）。

该脚本编译，但未按预期运行。肯定有问题，但我不知道。如果是明显的东西，我想那会很方便，否则如果只是格式等，我显然需要做更多的研究。

这次使用visual studio 2008 express编译，并清理干净。如果没有调试器，很难判断哪些是问题，例如缺少括号。

文件写入，编译和崩溃解决了..
