c# 中的程序路径

获取程序路径的方法
       // 2和3是调用方的路径
            //var path1 = System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName;
            //var path2 = System.Environment.CurrentDirectory;
            //var path3 = System.IO.Directory.GetCurrentDirectory();
            //var path4 = System.AppDomain.CurrentDomain.BaseDirectory;
            //var path5 = System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase;
            //var path6 = System.Windows.Forms.Application.StartupPath;
            //var path7 = System.Windows.Forms.Application.ExecutablePath;

如果是一个程序调用另一个程序，则 2和3是调用方的路径！
