读取全站仪数据(Longquanshan.txt)，将x, y, h 读取到数组中，以x从小到大排序，将排序的结果输出到文本文件中。

请提供D:\Newlongquanshan.txt内容

这个不用管他，路径有问题是正常的！

那个东西不用管！只需要检验语句有错误没，能不能继续优化下？

t 是什么啊？float.Parse(t[0]);

我也搞不懂！

这不是你写的代码啊

我搞不懂才来求教的，你们帮帮忙，看下可不可以用！

略微修改下 应该可以用了 希望对楼主有帮助 好奇 问一下 龙泉山什么地方?

随便弄的一个名字，这没什么讲究的。关键我是新手，可否写下你的思路，我好学习下！谢谢！
