如何在.net中将SID转换为String

我想将SID的System.Byte []类型转换为String。

我的代码：

string path = "LDAP://DC=abc,DC=contoso,DC=com"; DirectoryEntry entry = new DirectoryEntry(path); DirectorySearcher mySearcher = new DirectorySearcher(entry); mySearcher.Filter = "(&(objectClass=user)(samaccountname=user1))"; results = mySearcher.FindAll(); foreach (SearchResult searchResult in results) { Console.WriteLine(searchResult.Properties["ObjectSID"][0].ToString()); } 

我试过这个，但它从我当前登录的域中获取值，并且我需要来自给定的域。

 System.Security.Principal.NTAccount(user1) .Translate([System.Security.Principal.SecurityIdentifier]).value 

Answer 1

看一下SecurityIdentifier类。 然后你可以做一些简单的事情，比如

 var sidInBytes = (byte[]) *somestuff* var sid = new SecurityIdentifier(sidInBytes, 0); // This gives you what you want sid.ToString(); 

Answer 2

这是我所做的，经过一些阅读后，将值存储在oct中似乎更安全。 如果你不知道另一边是哪些服务器。 下面的代码显示了如何获得所需的结果

 private static string ExtractSinglePropertyValueFromByteArray(object value) { //all if checks etc has been omitted string propertyValue = string.Empty; var bytes = (byte[])value; var propertyValueOct = BuildOctString(bytes); // 010500....etc var propertyValueSec = BuildSecString(bytes); // S-1-5-...etc propertyValue = propertyValueSec; return propertyValue; } private static string BuildSecString(byte[] bytes) { return new SecurityIdentifier(bytes,0).Value.ToString(); } private static string BuildOctString(byte[] bytes) { StringBuilder sb = new StringBuilder(); for (int i = 0; i < bytes.Length; i++) { sb.Append(bytes[i].ToString("X2")); } return sb.ToString(); } 

Answer 3

在directoryEntry中加载属性后….

 var usrId = (byte[])directoryEntry.Properties["objectSid"][0]; var objectID = (new SecurityIdentifier(usrId,0)).ToString();
