使用c# DirectoryServices访问活动目录时出现问题

本文关键字：问题 DirectoryServices 访问 活动 使用 | 更新日期: 2023-09-27 18:08:20

  string ldapPath = "ldap://db.debian.org:389/uid=ma,ou=users,dc=debian,dc=org";
            DirectoryEntry dEntry = new DirectoryEntry(ldapPath, null, null, AuthenticationTypes.Anonymous);
            DirectorySearcher search = new DirectorySearcher(dEntry);
            search.Filter = "((objectClass=*))";
            search.FindAll();

我从我的c#表单应用程序使用上述代码。每当我调用FindAll()时，我都会得到一个异常，如下所示。

System.Runtime.InteropServices。COMException未处理

请告诉我我哪里做错了。

使用c# DirectoryServices访问活动目录时出现问题

LDAP路径中的LDAP协议标识符(LDAP://)必须为大写。如果将LDAP协议标识符写成小写，则会得到0x80005000错误代码(未知错误)。下面的代码片段应该可以工作:

string ldapPath = "LDAP://db.debian.org:389/uid=ma,ou=users,dc=debian,dc=org";
        DirectoryEntry dEntry = new DirectoryEntry(ldapPath, null, null,  AuthenticationTypes.Anonymous);
DirectorySearcher search = new DirectorySearcher(dEntry);
search.Filter = "((objectClass=*))";
search.FindAll();

希望有帮助。
