你可以用它来获得完整的路径。

 rfilename = openDialog1.InitialDirectory + openDialog1.FileName; 

更改下面的文件名使用

 FileInfo file =  new  FileInfo（  c：\ test.txt）; 
 file.Rename（  test2.txt）; 

 DialogResult result = openDialog1.ShowDialog();
  string fullpath = openDialog1.FileName;
  string extension = Path.GetExtension(fullpath);

  File.Copy(fullpath, @"C:\Users\Acer\Documents\Visual Studio 2010\Projects\sqlprocedure\sqlprocedure\Resources\Document\" + Filename + extension);

解决方案

you can use this to get full path.

rfilename = openDialog1.InitialDirectory + openDialog1.FileName;

FileInfo file = new FileInfo("c:\test.txt");
file.Rename("test2.txt");
