This is the core compiler and parser behind the Linq2Ldap.* NuGet libraries. It can compile C# LINQ Expressions into RFC 4515 (or 2254/1960) LDAP filter strings, and it can parse an LDAP filter into a LINQ Expression.
If you only want to use the filter compiler with no additional abstraction, you can do this:
// Goal: produce this filter string from a LINQ Expression
// filter = "(&(samaccountname=will*)(&(email=*uiowa*)(!(customprop=123))))";
string filter = new LdapFilterCompiler().Compile(
(MyUserModel u)
=> u.SamAccountName.StartsWith("will")
&& u.Email.Contains("uiowa")
&& u["customprop"] != "123");
var searcher = new DirectorySearcher();
searcher.Filter = filter;
// -- or --
var searchReq = new SearchRequest(targetOu, filter, /* ... */);Also supported query examples:
(MyUserModel u) => u.Title.Matches("univ*of*iowa"); // (title=univ*of*iowa)
(MyUserModel u) => u.Email.EndsWith("@gmail.com"); // (mail=*@gmail.com)
(MyUserModel u) => u["acustomproperty"].Contains("some val"); // (acustomproperty=*some val*)
(MyUserModel u) => u.Has("somekey"); // (somekey=*)For more information about models and properties, please visit the Wiki.
Wrappers around some of the search functionality in System.DirectoryServices and System.DirectoryServices.Protocols
can be found, here. These include, for example, LinqDirectorySearcher<T> and LinqSearchRequest<T>, respectively.
