Question

Application.StartupPath.Substring(0,Application.StartupPath.Substring())
Application.StartupPath.Substring(0,Application.StartupPath.Substring(0,Application.StartupPath.LastIndexOf("\\")).LastIndexOf("\\"))这句代码神马意思?这是指的哪条路径?

Answer 1

应该是：Application.StartupPath.Substring(0,Application.StartupPath.LastIndexOf("\\"))；Application.StartupPath：表示可启动的可执行文件的路径,就是你运行的这个程序的文件路径；.LastIndexOf("\\"))：表示获取字符串中最后一个"\"所在位置,是一个整数值；.Substring(a,b)：表示从字符串的第a的位置开始,截取长度为b的字符
希望能解决您的问题.
