Question

我正在尝试找到一种动态返回用户管理器电子邮件地址的方法。基本功能是一个下拉列表，用于在AD中选择正确的OU并为该OU构建用户的数据表。然后我有第二个下拉列表显示该数据表中的用户。当选择部门（OU）/用户时，我想将该用户经理的电子邮件地址提取到我的数据表中。任何建议都表示赞赏，谢谢！

我目前的下拉列表/查询代码是

    Protected Sub ddbranch_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddbranch.SelectedIndexChanged

     Dim searchRoot As New DirectoryEntry(ddbranch.SelectedValue)
         Using searchRoot
            Dim searchFilter As String = "((&(&(&(objectclass=user)(objectcategory=person))(!(userAccountControl=514)(!(!Description=*))))))"
            searchRoot.Username = "username"
            searchRoot.Password = "password"
            Dim ds As New DirectorySearcher(searchRoot, searchFilter)
            ds.PageSize = 500
            Using searchResults As SearchResultCollection = ds.FindAll()
                If searchResults.Count > 0 Then
                    ' make the users table and its columns

有一个manager-property包含管理器的DN（可分辨名称）。要获取他的电子邮件，您需要为给定的DN创建一个新的DirectoryEntry并获取mail-property。

实施例

If result.Properties.Contains("manager") Then
     Dim manager As New DirectoryEntry(result.Properties("manager")(0).ToString())
     row("mnger") = manager.Properties("mail")(0).ToString()
End If
