Question

我发现这个PowerShell脚本在域中搜索Exchange服务器。

    Function Get-ExchangeServerInSite {
    $ADSite = [System.DirectoryServices.ActiveDirectory.ActiveDirectorySite]
    $siteDN = $ADSite::GetComputerSite().GetDirectoryEntry().distinguishedName
    $configNC=([ADSI]"LDAP://RootDse").configurationNamingContext
    $search = new-object DirectoryServices.DirectorySearcher([ADSI]"LDAP://$configNC")
    $objectClass = "objectClass=msExchExchangeServer"
    $site = "msExchServerSite=$siteDN"
    $search.Filter = "(&($objectClass)($site))"
    $search.PageSize=1000
    [void] $search.PropertiesToLoad.Add("name")
    [void] $search.PropertiesToLoad.Add("msexchcurrentserverroles")
    [void] $search.PropertiesToLoad.Add("networkaddress")
    $search.FindAll() | %{
        New-Object PSObject -Property @{
            Name = $_.Properties.name[0]
            FQDN = $_.Properties.networkaddress |
                %{if ($_ -match "ncacn_ip_tcp") {$_.split(":")[1]}}
            Roles = $_.Properties.msexchcurrentserverroles[0]
        }
    }
}

    $role = @{
    2  = "MB"
    4  = "CAS"
    16 = "UM"
    32 = "HT"
    64 = "ET"
}


   foreach ($server in Get-ExchangeServerinSite) {
  $roles = ($role.keys | ?{$_ -band $server.roles} | %{$role.Get_Item($_)}) -join ", "
  $server | select Name, @{n="Roles";e={$roles}},FQDN
}

因为我在C＃代码中需要相同的任务而不使用PowerShell。我尝试以相同的方式使用.Net类，甚至调试两个脚本，信息是相同的。

现在我的问题。 PowerShell脚本正确显示服务器，C＃代码返回空集合。

这是C＃

string siteDN = ActiveDirectorySite.GetComputerSite().GetDirectoryEntry().Properties["distinguishedName"].Value.ToString();

DirectoryEntry RootDSE = new DirectoryEntry( @"LDAP://RootDSE" );
string baseStr = @"LDAP://" + RootDSE.Properties["configurationNamingContext"].Value ;

DirectorySearcher searcher = new DirectorySearcher(baseStr ); 

string classObj = "objectClass=msExchExchangeServer";
string site = "msExchServerSite="+siteDN;
searcher.Filter = string.Format("(&({0})({1}))",classObj,site);

searcher.PropertiesToLoad.Add( "name" );
searcher.PageSize = 1000;
searcher.ServerTimeLimit = new TimeSpan(0,1,0);
searcher.CacheResults = false;

SearchResultCollection coll = searcher.FindAll();

我能找到的唯一区别是PowerShell代码中的[ADSI]标记，但我无法找到C＃部分的内容。

访问AD信息的问题（PowerShell脚本工作，C＃代码不）
