扩展UserPrincipal类 [英] Extend UserPrincipal class
本文介绍了扩展UserPrincipal类的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我对UserPrincipal类进行了扩展,以检索我需要的一些缺少的属性:
I do the extension of the UserPrincipal class to retrieve some missing properties that i need:
[DirectoryObjectClass("user")]
[DirectoryRdnPrefix("CN")]
class UserPrincipalExt : UserPrincipal
{
public UserPrincipalExt(PrincipalContext context)
: base(context)
{
}
[DirectoryProperty("department")]
public string Department
{
get
{
if (ExtensionGet("department").Length != 1)
return null;
return (string)ExtensionGet("department")[0];
}
set
{
this.ExtensionSet("department", value);
}
}
[DirectoryProperty("company")]
public string Company
{
get
{
if (ExtensionGet("company").Length != 1)
return null;
return (string)ExtensionGet("company")[0];
}
set
{
this.ExtensionSet("company", value);
}
}
[DirectoryProperty("c")]
public string CountryAbbreviation
{
get
{
if (ExtensionGet("c").Length != 1)
return null;
return (string)ExtensionGet("c")[0];
}
set
{
this.ExtensionSet("c", value);
}
}
}
然后,我可以像这样轻松地进行搜索:
Then, i can search easily like this:
PrincipalContext principalContext = new PrincipalContext(ContextType.Domain, myDomain);
UserPrincipalExt userExt = new UserPrincipalExt(principalContext);
PrincipalSearcher searcher = new PrincipalSearcher(userExt);
userExt.GivenName = "blabla";
userExt.EmailAddress ="text here";
PrincipalSearchResult<Principal> searchTmp = null;
searcher.QueryFilter = userExt;
searchTmp = searcher.FindAll();
因此,我的新任务和当前问题是这样的:对于ActiveDirectory中搜索到的组,当然必须使用扩展类来获取用户列表.
So, my new task, and my current problem, is this: for the searched Group in ActiveDirectory, it is necessary get the list of the users, using the extended class, of course.
GroupPrincipal group = (GroupPrincipal)collection.FirstOrDefault();
foreach (Principal pRes in group.GetMembers())
{
//This doesnt work of course.
// return null value.
UserPrincipalExt user = pRes as UserPrincipalExt;
}
我如何实现目标?
作为解决方法,我已经创建了一个函数来检索属性:
As workaround i have made a function to retrieve the properties anyway :
private string GetExtendedProperty(Principal principal, string propertyTo)
{
string property = "";
try
{
DirectoryEntry directoryEntry = principal.GetUnderlyingObject() as DirectoryEntry;
if (directoryEntry.Properties.Contains(propertyTo))
{
property = directoryEntry.Properties[propertyTo].Value.ToString();
}
else
{
property = "";
}
}
catch (Exception ex)
{
Logger.ScriviLog(4, this.GetType().Name, MethodBase.GetCurrentMethod().Name, ex.Message);
}
return property;
}
谢谢.
推荐答案
在扩展类中覆盖FindByIdentity方法.
Override the FindByIdentity method in your extended class.
public new static User FindByIdentity(PrincipalContext context, string identityValue)
{
return (User)FindByIdentityWithType(context, typeof(User), identityValue);
}
public new static User FindByIdentity(PrincipalContext context, IdentityType identityType, string identityValue)
{
return (User)FindByIdentityWithType(context, typeof(User), identityType, identityValue);
}
然后使用扩展类FindByIdentity方法搜索
Then search using the extended class FindByIdentity method
var user = User.FindByIdentity(
DomainContext,
"name"
);
