如题
先上懒人下载链接
从unity2017开始发布程序，日志就不在程序同级目录了。这使得发布之后找日志、查bug比较麻烦。当然可以发布时选择dev模式调试，在屏幕上查看，但不方便。
先看一下一般找到打开log日志需要多少步骤：

一般打开streamingAsset文件夹需要的步骤

本帖主要解决的问题：
1.exe同级目录一键打开log日志
2.exe同级目录一键打开streamingAssets配置目录
3.streamingAssets目录一键返回exe根目录
4.自动创建exe快捷方式至电脑桌面

实现原理
命令行……批处理……bat
当然也有直接在C#代码里用Shell命令实现的，我是觉得还得拖进来dll太麻烦，不如直接用计算机自带的bat命令！！！
