DirectorySearcher.FindAll卡住了

Question

我正在尝试从Active Directory中获取所有的用户。

private void Form1_Load(object sender, EventArgs e)
{
    string[] RetProps = new string[] { "SamAccountName", "DisplayName" };
    List<string[]> users = new List<string[]>();

    foreach (SearchResult User in GetAllUsers("localhost", RetProps))
    {
        DirectoryEntry DE = User.GetDirectoryEntry();
        try
        {
            users.Add(new string[] { DE.Properties["SamAccountName"][0].ToString(), DE.Properties["DisplayName"][0].ToString() });
        }
        catch
        {
        }
    }
}

internal static SearchResultCollection GetAllUsers(string DomainName, string[] Properties)
{
    DirectoryEntry DE = new DirectoryEntry("LDAP://" + DomainName);
    string Filter = "(&(objectCategory=organizationalPerson)(objectClass=User))";
    DirectorySearcher DS = new DirectorySearcher(DE);
    DS.PageSize = 10000;
    DS.SizeLimit = 10000;
    DS.SearchScope = SearchScope.Subtree;
    DS.PropertiesToLoad.AddRange(Properties); DS.Filter = Filter;
    SearchResultCollection RetObjects = DS.FindAll();
    return RetObjects;
 }

但是当到达DS.FindAll();中的GetAllUsers函数时，它就被卡住了。

问题是我没有在(调试->异常)中启用“公共语言运行时异常”。除了DS.FindAll()；存在运行时，因此它停止执行剩余的代码。
