Pass the full path (the one including the file name) to the System.IO.Path.GetDirectoryNamemethod. This will strip out the file name and return the full path to the directory containing that file.
将完整路径（包括文件名的路径）传递给System.IO.Path.GetDirectoryName方法。这将去掉文件名并返回包含该文件的目录的完整路径。
For example:
例如：
Dim filePath As String = "C:\MyDir\MySubDir\myfile.ext"
Dim directoryPath As String = Path.GetDirectoryName(filePath)
Places the following string in the directoryPathvariable:
将以下字符串放入directoryPath变量中：
C:\MyDir\MySubDir
C:\MyDir\MySubDir

Dim dir As String = System.Environment.GetFolderPath(Environment.SpecialFolderOption.None)
The value of dirwill give you the path only.
的值dir只会给你路径。
