我可以从ASP.NET中的DirectorySearcher获取超过1000条记录吗？

DirectorySearcher searcher = new DirectorySearcher("mysearchstring");
searcher.PageSize = 1000; // 设置页面大小
SearchResultCollection results = searcher.FindAll();

PagedDataSource dataSource = new PagedDataSource();

// 获取页面大小
dataSource.PageSize = results.Properties["TotalRows"].Value;

// 计算页数
int totalPages = (int) Math.Ceiling((double) results.Properties["TotalRows"].Value / results.Properties["PageSize"].Value);

// 创建分页信息
for (int i = 1; i <= totalPages; i++)
{
    dataSource.PageCount = totalPages;
    dataSource.CurrentPageIndex = i - 1;
}

// 绑定数据
GridView1.DataSource = dataSource;
GridView1.DataBind();
