Question

如何从活动目录中获取用户管理器电子邮件ID？我已经编写了代码，我可以根据用户ID获取用户的名字，姓氏，电子邮件ID和经理姓名，但我想获得经理电子邮件ID以及他的经理姓名。

有人可以帮我解决这个问题吗？这是我的代码：

protected void ddlAdsuser_SelectedIndexChanged(object sender, EventArgs e)
{
    DirectoryEntry root = new DirectoryEntry("LDAP://RootDSE");
    string myDomain = root.Properties["defaultNamingContext"].Value.ToString();
    DirectoryEntry domain = new DirectoryEntry("LDAP://" + myDomain);
    DirectorySearcher dsUsers = new DirectorySearcher(domain);
    dsUsers.Filter = "(userPrincipalName=" + ddlAdsuser.Text + ")";
    foreach (SearchResult sResultSet in dsUsers.FindAll())
        {
            lblfname.Text = GetProperty(sResultSet, "givenName");
            lbllname.Text = GetProperty(sResultSet, "sn");
            lblemail.Text = GetProperty(sResultSet, "mail");

            string Manager = string.Empty;
            Manager = GetProperty(sResultSet, "manager");
            if (Manager != "")
            {
                if (Manager.Contains("CN="))
                {
                    int Length = Manager.IndexOf(',');
                    Manager = Manager.Substring(3, Length - 3);
                }
                else
                {
                    Manager = string.Empty;
                }
            }            
            lblManagerID.Text = Manager;  //Here displaying the manager name.
        }     
}

public static string GetProperty(SearchResult searchResult, string PropertyName)
{
    if (searchResult.Properties.Contains(PropertyName))
    {
        return searchResult.Properties[PropertyName][0].ToString();
    }
    else
    {
        return string.Empty;
    }
}

Answer 1

DirectorySearcher objDirSearch = new DirectorySearcher(SearchRoot);
DirectoryEntry dentUser = null;
string pstrFieldName, pstrValue;

pstrFieldName = "company";
pstrValue = "12345"; //Employee number

/*setting the filter as per the employee number*/
objDirSearch.Filter = "(&(objectClass=user)(" + pstrFieldName + "=" + pstrValue + "))";

SearchResult objResults = objDirectorySearch.FindOne();

dentUser = new DirectoryEntry(objResults.Path);}

string strManager = dentUser.Properties["manager"].Value.ToString();

PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
UserPrincipal user = UserPrincipal.FindByIdentity(ctx, IdentityType.DistinguishedName, strManager);

string strManagerMailID = user.EmailAddress;

Answer 2

简单的代码，工作得很好：

    public static string GetEmail(string userId)
    {
        PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
        UserPrincipal user = UserPrincipal.FindByIdentity(ctx, IdentityType.SamAccountName, userId);
        return user.EmailAddress;
    }

您必须添加程序集System.DirectoryServices.AccountManagement.dll。如果您遇到与AD连接的任何问题，可以尝试在PrincipalContext构造函数中添加AD服务器名称。

只需再次搜索经理。

请注意，构建查询过滤器的方法有问题，您需要转义一些字符（尤其是"引号），以避免根据用户输入查询损坏。
