C＃和Active Directory：测试OU是否存在

Question

在使用C＃创建Active Directory之前，如何测试Active Directory中是否存在组织单位？

Answer 1

There's a .Exists() method on the DirectoryEntry which you can use - assuming you have the correct LDAP path for your OU!

if (DirectoryEntry.Exists("LDAP://" + objectPath))
{
   // ......
}

Your main problem will be: the path you're using is wrong - the Users is a generic container and thus needs to be addressed like this:

LDAP://192.168.0.1/CN=Users

Note the CN= prefix. If you had an actual organizational unit, it would have to be prefixed with OU=
