[C#]获取文件夹的名称

C# code

FolderBrowserDialog folderBrowserDialog = new FolderBrowserDialog();                        if(folderBrowserDialog.ShowDialog(this) == DialogResult.OK)            {                fullDirectoryName = folderBrowserDialog.SelectedPath;                directoryName = Path.GetDirectoryName(fullDirectoryName);                this.txt_DireName.Text = fullDirectoryName;            }

我用的是vs2003，GetDirectoryName方法的返回值怎么不是文件夹名称？
应该怎么获取绝对路径的文件夹的名称？
谢谢~~

[解决办法]

C# code

this.txt_DireName.Text = new System.IO.DirectoryInfo(folderBrowserDialog.SelectedPath).Name;

DirectoryInfo 类的操作
