vb.net建立文件夹并给予帐号完全控制权限

你可以使用 `Directory.CreateDirectory()` 方法创建文件夹，并使用 `DirectorySecurity` 类为该文件夹设置访问控制。以下是一个示例代码：

Imports System.Security.AccessControl
Imports System.IO

Dim folderPath As String = "C:\TestFolder"
Dim directoryInfo As DirectoryInfo = Directory.CreateDirectory(folderPath)

' Create a new security object
Dim directorySecurity As DirectorySecurity = directoryInfo.GetAccessControl()

' Add a rule giving full control to a specific user
Dim rule As FileSystemAccessRule = New FileSystemAccessRule("USERNAME", FileSystemRights.FullControl, AccessControlType.Allow)
directorySecurity.AddAccessRule(rule)

' Set the new access rule
directoryInfo.SetAccessControl(directorySecurity)

请注意，在以上代码中，你需要将 `USERNAME` 替换为你想要授权的用户的帐户名。
