ASP.NET-Active Direcotry编程示例

查找指定的AD帐号

using (DirectoryEntry de = new DirectoryEntry("LDAP://RootDSE"))
{
string DCName = (string)de.Properties["defaultNamingContext"][0];

using (DirectoryEntry DC = new DirectoryEntry("LDAP://" + DCName))
{
using (DirectorySearcher deSearch = new DirectorySearcher( ))
{
deSearch.SearchRoot = DC;
deSearch.SearchScope = SearchScope.Subtree;
deSearch.Filter = "(&(&(objectCategory=person)(objectClass=user))(sAMAccountName=" + myAccountName+ "))";
using (SearchResultCollection results = deSearch.FindAll( ))
{
if (results.Count == 0)
{
return false;
}
return true;
}
}
}
}

如何使用DirectoryEntry的长构造函数

using (DirectoryEntry group = DirectoryEntry(ADPath, ADUser, ADPassword, AuthenticationTypes.Secure))
{
string filter = "(objectClass=Group)";
string[ ] properties = new string[ ] ...{ "cn", "displayname", "distinguidshedName" };
using (DirectorySearcher search = new DirectorySearcher(group, filter, properties, SearchScope.Base))
{
search.AttributeScopeQuery = "member";
using (SearchResultCollection results = search.FindAll( ))
{

for (int i = 0; i < results.Count; i++)
{
using (DirectoryEntry de = results[i].GetDirectoryEntry( ))
{
// add your process code....

}
}
}
}
}
