推荐答案
如果您使用的是.NET 3.5及更高版本，则应签出System.DirectoryServices.AccountManagement(S.DS.AM)命名空间.在这里阅读所有内容:
If you're on .NET 3.5 and up, you should check out the System.DirectoryServices.AccountManagement (S.DS.AM) namespace. Read all about it here:
- Managing Directory Security Principals in the .NET Framework 3.5
- MSDN docs on System.DirectoryServices.AccountManagement
基本上，您可以定义域上下文并轻松找到AD中的用户和/或组:
Basically, you can define a domain context and easily find users and/or groups in AD:
// set up domain context
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
// find a user
UserPrincipal user = UserPrincipal.FindByIdentity(ctx, "SomeUserName");
if(user != null)
{
// your user exists - do something here....
}
else
{
// your user in question does *not* exist - do something else....
}
或在VB.NET中:
' set up domain context
Dim ctx As New PrincipalContext(ContextType.Domain)
' find a user
Dim user As UserPrincipal = UserPrincipal.FindByIdentity(ctx, "SomeUserName")
If user IsNot Nothing Then
' your user exists - do something here....
Else
' your user in question does *not* exist - do something else....
End If
新的S.DS.AM使得与AD中的用户和组玩起来非常容易！
The new S.DS.AM makes it really easy to play around with users and groups in AD!
