c# - 如何从 LDAP 路径字符串中提取项目

Question

是否有一种“正确”的方式从以下字符串中检索例如 CN:

“LDAP://CN=名字姓氏,OU=域管理员,DC=DOMAIN1,DC=co,DC=uk”

我从 DirectorySearcher 检索到的内容

目前我正在这样做:

var name = result.Path.Split('=')[1].Split(',')[0];

但这感觉不是最好的方法 - 有人知道任何替代方法吗？

您可以查看这篇文章:An RFC 2253 Compliant Distinguished Name Parser

There are three main classes in this code:

• DN, which represents a full distinguished name
• RDN, which represents a relative distinguished name

• RDNComponent, which represents the individual components of a multivalued RDN

  DN myDN = new DN(@"CN=Pete Everett\, esq.,OU=People,DC=example,DC=com");

To print out a DN object, you use its ToString() method, as you'd expect.

Console.WriteLine(myDN.ToString());
// prints out:
// CN=Pete Everett\, esq.,OU=People,DC=example,DC=com

But if you'd like more control over the formatting, you can specify categories of characters to escape.

Console.WriteLine(myDN.ToString(EscapeChars.None));
// prints out:
// CN=Pete Everett, esq.,OU=People,DC=example,DC=com
// (Note that this is an incorrect DN format, and will not parse correctly.)

To get the parent object of a given DN object, you can use its Parent property.

DN myParentDN = myDN.Parent;
Console.WriteLine(myParentDN.ToString());
// prints out:
// OU=People,DC=example,DC=com
