C# 获取工作目录

using System.Windows.Forms; // 添加库

namespace WindowsFormsApp1
{
    class DBHelper
    {
        public static void getDebugpath()
        {
            // 获取Debug的路径
            string debugpath = Application.StartupPath;
            // debugpath: F:\C#_Project\test\test5\WindowsFormsApp1\WindowsFormsApp1\bin\Debug
            string binpath = debugpath.Substring(0, debugpath.LastIndexOf("\\"));
            // binpath: F:\C#_Project\test\test5\WindowsFormsApp1\WindowsFormsApp1\bin
            string dbpath = binpath.Substring(0, binpath.LastIndexOf("\\"));
            // dbpath: F:\C#_Project\test\test5\WindowsFormsApp1\WindowsFormsApp1
            Console.WriteLine("debugpath: " + debugpath);
            Console.WriteLine("binpath: " + binpath);
            Console.WriteLine("dbpath: " + dbpath);
        }
        static void Main(string[] args)
        {
            GetConnection();
        }
    }
 
}

使用System.Windows.Forms中的Application.StartupPath
