获取文件夹的权限级别

Question

我有一个检查权限级别的EventHandler。

private void button1_Click(object sender, EventArgs e) 
    { 
     int id = 1; 
      XMLPermSheet.CreateXML(); 
      string directory = textBox1.Text; 
      DirectoryInfo di = new DirectoryInfo(directory); 
      DirectoryInfo[] sdi = di.GetDirectories(); 
      foreach (DirectoryInfo tdi in sdi) 
      { 
       if (!tdi.ToString().EndsWith("System Volume Information") && !tdi.ToString().Contains("$RECYCLE.BIN")) 
       { 
        XMLPermSheet.AddPath(tdi.ToString(), id); 
        DirectorySecurity ds = tdi.GetAccessControl(); 

        foreach (AccessRule rule in ds.GetAccessRules(true, true, typeof(NTAccount))) 
        { 
         richTextBox1.AppendText(string.Format("{0} || Identity = {1}; Access = {2} \r\n", tdi.ToString(), 
         rule.IdentityReference.Value, rule.AccessControlType)); 
         XMLPermSheet.AddIdentity(rule.IdentityReference.Value.ToString(), rule.AccessControlType.ToString(), tdi.ToString()); 
        } 

        id += 1; 
       } 
      } 
    } 

rule.AccessControlType.ToString（）返回只 “允许” 或 “拒绝”，但我需要得到的东西是：

查看：真
地址：真
修改：假
删除：假

我该如何做到这一点？

您必须更改AccessRule在您的foreach到FileSystemAccessRule。然后你可以访问属性FileSystemRights。这answer解释如何获得权利。

短版，如何检查，如果用户或组具有权限：

//Example: Change  
bool hasChangePermission = rule.FileSystemRights.HasFlag(FileSystemRights.ChangePermissions); 

//Example: Write 
bool hasWritePermission = rule.FileSystemRights.HasFlag(FileSystemRights.Write); 

这里有一个小例子方法：

public string GetRuleAsString(FileSystemAccessRule rule) 
{ 
    string userName = rule.IdentityReference.Value; 

    //Example: Change  
    bool hasChangePermission = rule.FileSystemRights.HasFlag(FileSystemRights.ChangePermissions); 

    //Example: Write 
    bool hasWritePermission = rule.FileSystemRights.HasFlag(FileSystemRights.Write); 

    return String.Format("{0}\n Change: {1}\n Write: {2}", userName, hasChangePermission, hasWritePermission); 
}
