System.IO.Path.GetFullPath(openFileDialog1.FileName);                              //绝对路径

System.IO.Path.GetExtension(openFileDialog1.FileName);                           //文件扩展名

System.IO.Path.GetFileNameWithoutExtension(openFileDialog1.FileName); //文件名没有扩展名

System.IO.Path.GetFileName(openFileDialog1.FileName);                           //得到文件

System.IO.Path.GetDirectoryName(openFileDialog1.FileName);                  //得到路径
