C＃DirectorySearcher过滤器

Question

I am trying to fetch records from LDAP using DirectorySearcher. The following is the filter I am using:

(&(objectCategory=person)(objectClass=user)(employeeType=A))

I need to modify this filter to fetch records for employeeType either A or B.

Please help.

Answer 1

In your Expression you want to replace employeeType=A by employeeType=A OR employeeType=B

(&(objectCategory=person)(objectClass=user)(employeeType=A))

So you replace (employeeType=A) by (|(employeeType=A)(employeeType=B)) and get

(&(objectCategory=person)(objectClass=user)(|(employeeType=A)(employeeType=B)))
