c# - 微软交换 : How To Resolve A Distinguished Name

Question

我该如何解决:

/O=CHEESE/OU=FIRST ADMINISTRATIVE GROUP/CN=RECIPIENTS/CN=LHALA1

电子邮件地址？我必须使用 Exchange Web 服务吗？

Answer 1

我假设这是 legacyExchangeDN 属性。

尝试这样的事情:

string dn = "/O=CHEESE/OU=FIRST ADMINISTRATIVE GROUP/" +
        "CN=RECIPIENTS/CN=LHALA1";
string MailAddress=string.Empty;
string user = string.Empty;

using (DirectorySearcher ds = new DirectorySearcher())
{
    ds.Filter = string.Format("(&(ObjectClass=User)(legacyExchangeDN={0}))", 
            dn);
    SearchResultCollection src = ds.FindAll();
    if (src.Count > 1)
    {
        //Oops too many!
    }
    else
    {
        user = src[0].Properties["samAccountName"][0].ToString();
        MailAddress = src[0].Properties["Mail"][0].ToString();
    }
}
