如何給讀/寫權限的文件夾爲一組

Question

我寫了下面的代碼給讀取權限的組，但我得到anerror：

"The trust relationship between the primary domain and the trusted domain failed."

如果我給一個用戶名，而不是它正在工作。

DirectoryInfo myDirectoryInfo = new DirectoryInfo(path); 
DirectorySecurity myDirectorySecurity = myDirectoryInfo.GetAccessControl(); 
string group = "groupName"; 
myDirectorySecurity.AddAccessRule(new FileSystemAccessRule(group,FileSystemRights.Read, AccessControlType.Deny)); 
myDirectoryInfo.SetAccessControl(myDirectorySecurity); 

Answer 1

每MSDN文檔FileSystemAccessRule：

Initializes a new instance of the FileSystemAccessRule class using the name of a user account, a value that specifies the type of operation associated with the access rule, and a value that describes whether to allow or deny the operation.

編輯：看起來像構造函數只與用戶賬戶中使用（您可能需要爲組SID）。你應該使用帶有IdentityReference的構造函數。以一個示例爲例...
