我试图将它添加到我的代码在这里

DataSet dataSet = new DataSet(); 
string sql = "SELECT key, fdate, user, perm, sfolder FROM permuser WHERE  fdate=CURDATE()"; 

MySqlConnection connection = new MySqlConnection(MyConString); 
MySqlCommand cmdSel = new MySqlCommand(sql, connection); 
new MySqlDataAdapter(cmdSel).Fill(dataSet, "permuser"); 


foreach (DataRow row in dataSet.Tables["permuser"].Rows) 
    { 
     string fuser = row["user"].ToString(); 
     string pathtxt = row["sfolder"].ToString(); 

     DirectoryInfo myDirectoryInfo = new DirectoryInfo(pathtxt); 
     DirectorySecurity myDirectorySecurity = myDirectoryInfo.GetAccessControl(); 
     string User = System.Environment.UserDomainName + "\\" + fuser; 


       myDirectorySecurity.RemoveAccessRule(new FileSystemAccessRule(User, FileSystemRights.Write | FileSystemRights.Read, InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit, 
    PropagationFlags.None, AccessControlType.Allow)); 

       myDirectoryInfo.SetAccessControl(myDirectorySecurity); 
        //it should go here 
    } 

connection.Close(); 
connection.Dispose(); 
} 


catch (MySqlException ex) 
{ 
Console.WriteLine(ex.Message); 
Environment.Exit(0); 
}

我们使用以下命令从他们无法访问的文件夹中删除用户/组。

var accountToRemove = "Some account"; 
var security = Directory.GetAccessControl(path); 
var rules = security.GetAccessRules(true, true, typeof(NTAccount)); 

foreach (FileSystemAccessRule rule in rules) 
{ 
    if (rule.IdentityReference.Value == accountToRemove) 
     security.RemoveAccessRuleSpecific(rule); 

} 

具有以下

foreach (DataRow row in dataSet.Tables["permuser"].Rows) 
{ 
    string fuser = row["user"].ToString(); 
    string pathtxt = row["sfolder"].ToString(); 

    DirectoryInfo myDirectoryInfo = new DirectoryInfo(pathtxt); 
    DirectorySecurity myDirectorySecurity = myDirectoryInfo.GetAccessControl(); 
    string User = System.Environment.UserDomainName + "\\" + fuser; 

    var rules = myDirectorySecurity.GetAccessRules(true, true, typeof(NTAccount)); 
    foreach(var rule in rules) 
    { 
     if (rule.IdentityReference.Value == User) 
      security.RemoveAccessRuleSpecific(rule); 

    } 
}
