如果您指的是应用程序启动的路径，请使用：

If you mean the path where your app got started then use:

Application.StartupPath

由于进一步编辑信息：

EDIT due to further information:

OpenFileDialog ofd = new OpenFileDialog();

//Change this to your needs
ofd.Multiselect = true;

if (ofd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
   //SingleSelect
   //string fullPath = ofd.FileName;

   //MulitSelect
   if (ofd.FileNames.Length > 0)
   {
     string[] fullPaths = ofd.FileNames;
   }
}

Environment.CurrentDirectory来检索当前目录



谢谢，

Environment.CurrentDirectory to retreive the current directory

Thanks,
