在程序中访问Access写相对路径

string dataDir = AppDomain.CurrentDomain.BaseDirectory;

            if (dataDir.EndsWith(@"\bin\Debug\")

                || dataDir.EndsWith(@"\bin\Release\"))

            {

                dataDir = System.IO.Directory.GetParent(dataDir).Parent.Parent.FullName;

                AppDomain.CurrentDomain.SetData("DataDirectory", dataDir);

            }
