以编程方式确定当前域控制器

问题描述

我需要查询当前域控制器，可能主要是为了更改用户密码.

I need to query current domain controller, probably primary to change user password.

(P)DC 名称应该是完全限定的，即 DC=pdc,DC=example,DC=com(如何正确命名此类符号?)

(P)DC name should be fully qualified, i.e. DC=pdc,DC=example,DC=com (how to properly name such notation?)

如何使用 C# 来完成?

How can it be done using C#?

推荐答案

(需要 System.DirectoryServices.AccountManagement.dll):

(requires System.DirectoryServices.AccountManagement.dll):

using (var context = new System.DirectoryServices.AccountManagement.PrincipalContext(ContextType.Domain))
{
    string server = context.ConnectedServer; // "pdc.examle.com"
    string[] splitted = server.Split('.'); // { "pdc", "example", "com" }
    IEnumerable<string> formatted = splitted.Select(s => String.Format("DC={0}", s));// { "DC=pdc", "DC=example", "DC=com" }
    string joined = String.Join(",", formatted); // "DC=pdc,DC=example,DC=com"

    // or just in one string

    string pdc = String.Join(",", context.ConnectedServer.Split('.').Select(s => String.Format("DC={0}", s)));
}
