对单个文件设置安全性？

我试图在单个文件上实现安全性，以防止访问该文件或删除它，这里是代码：

//Create file
FileStream oFileStreamDec = new FileStream(@"C:\Decrypted_AMS.cfg", FileMode.Create, FileAccess.ReadWrite, FileShare.None);
oFileStreamDec.Write(DecryptedXML, 0, DecryptedXML.Length);
//Create access rules
FileSystemAccessRule oAccessRuleFullControl = new FileSystemAccessRule(WindowsIdentity.GetCurrent().Name, FileSystemRights.FullControl, AccessControlType.Allow);
//Create file security and apply rules to it
FileSecurity oFileSecurity = new FileSecurity(@"C:\Decrypted_AMS.cfg", AccessControlSections.All);
oFileSecurity.AddAccessRule(oAccessRuleFullControl);
//Here is the problem !!!!!!!
oFileStreamDec.SetAccessControl(oFileSecurity);
oFileStreamDec.Close();

我尝试在关闭流并设置访问控制后再次打开该文件，但出现了同样的问题，我已经尝试过也它在文件流以外的普通文件上，也一样，我有一个具有所有权限的管理员帐户，那么问题是什么以及如何解决它？

I am trying to implement a security on a single file to prevent either accessing the file or deleting it here is the code :

//Create file
FileStream oFileStreamDec = new FileStream(@"C:\Decrypted_AMS.cfg", FileMode.Create, FileAccess.ReadWrite, FileShare.None);
oFileStreamDec.Write(DecryptedXML, 0, DecryptedXML.Length);
//Create access rules
FileSystemAccessRule oAccessRuleFullControl = new FileSystemAccessRule(WindowsIdentity.GetCurrent().Name, FileSystemRights.FullControl, AccessControlType.Allow);
//Create file security and apply rules to it
FileSecurity oFileSecurity = new FileSecurity(@"C:\Decrypted_AMS.cfg", AccessControlSections.All);
oFileSecurity.AddAccessRule(oAccessRuleFullControl);
//Here is the problem !!!!!!!
oFileStreamDec.SetAccessControl(oFileSecurity);
oFileStreamDec.Close();

I have tried to open the file again after closing the stream and setting the access control but same problem occurred, i have tried also it on a normal file other than a file stream and the same too, I have an admin account with all permissions so What is the problem and how to Solver it ?

试试这个，

FileStream oFileStreamDec = new FileStream(@"C:\Decrypted_AMS.cfg", FileMode.Create, FileAccess.ReadWrite, FileShare.None);
oFileStreamDec.Write(DecryptedXML, 0, DecryptedXML.Length);
// Close the File first
oFileStreamDec.Close();
//Create file security and apply rules to it
FileSecurity oFileSecurity = new FileSecurity();
oFileSecurity.AddAccessRule(new System.Security.AccessControl.FileSystemAccessRule("Everyone", System.Security.AccessControl.FileSystemRights.FullControl, System.Security.AccessControl.AccessControlType.Allow));
System.IO.File.SetAccessControl(@"C:\Decrypted_AMS.cfg", oFileSecurity);

try this,

FileStream oFileStreamDec = new FileStream(@"C:\Decrypted_AMS.cfg", FileMode.Create, FileAccess.ReadWrite, FileShare.None);
oFileStreamDec.Write(DecryptedXML, 0, DecryptedXML.Length);
// Close the File first
oFileStreamDec.Close();
//Create file security and apply rules to it
FileSecurity oFileSecurity = new FileSecurity();
oFileSecurity.AddAccessRule(new System.Security.AccessControl.FileSystemAccessRule("Everyone", System.Security.AccessControl.FileSystemRights.FullControl, System.Security.AccessControl.AccessControlType.Allow));
System.IO.File.SetAccessControl(@"C:\Decrypted_AMS.cfg", oFileSecurity);
