c# everything扫描共享盘示例
背景
由于我们公司不同部门文件都放在共享盘中，我们需要将公盘文件上传阿里云或ftp，做增量查询（上传过的数据不会在上传）
由于扫描公盘需求越来越多，数据量越来越大，之前通过递归扫描磁盘的方式太慢。
所以研究通过everything搜索文件方式替换之前的方式。 研究下来发现该方式扫描磁盘速度非常快。
那么废话不多说，直接上代码。
如果需要扫描共享盘的话:
(如果是本地磁盘可以忽略1)
1.需要安装一下everything，在选项-文件夹-添加一下你的文件目录
2.需要将Everything32.dll copy到你的bin目录下
3.可以copy代码，运行

ArrayList array = new ArrayList(); foreach (var item in list) { array.Add(item); } }
返回的结果就是你要上传的文件列表，如果有需要可以根据自己的需求在次拓展。
