出于某种原因,星期一,上周工作的代码突然开始给我以下错误。

System.DirectoryServices.DirectoryServicesCOMException(0x800700EA):有更多数据可用。当我尝试针对广告查询执行FindAll时会发生这种情况

我制作了一个小型控制台应用程序,并能够重现错误。会导致此错误的原因是什么?

   static void Main(string[] args)
    {
        var propToLoad = new StringCollection();
        propToLoad.Add(ADProperty.DistinguishedName);

         DirectoryEntry de = new DirectoryEntry();
        de.Path = "MySearchROOT";

        DirectorySearcher ser = new DirectorySearcher(de);
        ser.Filter = "(&(&(&(dfaitUserType=PER)(objectCategory=person)(objectClass=user)(!dfaitObjectStatus=*)(!msExchHideFromAddressLists=TRUE))(&(sAMAccountName=*)(dfaitOrgCode=*)(objectCategory=person)(objectClass=user)(!dfaitObjectStatus=*)(!msExchHideFromAddressLists=TRUE)))(|(employeeType=CBS)(employeeType=LES)(employeeType=CON)(employeeType=OGD)(employeeType=OTH)(employeeType=MIN)))";


// We made constants to represent all the Ad properties
            ser.PropertiesToLoad.Add(ADProperty.Surname);
            ser.PropertiesToLoad.Add(ADProperty.GivenName);
            ser.PropertiesToLoad.Add(ADProperty.Mail);
            ser.PropertiesToLoad.Add(ADProperty.DisplayName);
            ser.PropertiesToLoad.Add(ADProperty.DfaitEdsId);

        ser.Sort.PropertyName = ADProperty.DfaitEdsId;
        ser.Sort.Direction = SortDirection.Ascending;

        var returnValue = ser.FindAll();

    }

                    }

        return returnValue;

对于上面的测试示例,我注释掉了排序并且它有效。

对于我的主要应用程序,我仍然收到错误。

对于此错误消息,此帖子仍然适用于.net 4.0。

一旦开始为您的请求提供太多结果,就会发生此错误 虽然这似乎没有很好地记录,但 findall 可以处理的对象数量显然有限,即使启用了分页

一种方法是切换到较低级别的访问权限并使用 System.DirectoryServices.Protocols 而不是分页。
您可以使用此处提供的代码: http://dunnry.com/blog/PagingInSystemDirectoryServicesProtocols.aspx

另一种选择似乎是使用KB 833879的解决方法并激活waitForPagedSearchData选项。但是正如您在答案中所描述的那样,在所有情况下显然都无法解决问题。但请确保您为实际使用的DirectoryServices版本设置了选项,如下所述: https://dirteam.com/tomek/2006/11/09/more-data-is-available-exception-when-searching-with-s-ds/
