UserSearchProvider.UserSearchService.Search（UserSearchCriteriaCollection
c:\Users\stemarie\Documents\Visual中的标准、操作是否有人对此问题有任何见解/建议？我们很快就能解决这一问题，只需要解决最后一个问题。事实证明，这一点很有效：
try
{
response = (SearchResponse)con.SendRequest(request);
return response.Entries.Cast<SearchResultEntry>()
.Select(entry => entry.Attributes)
.Select(x => GetADUserSearchItemFromADProperties(x, logMessage))
.Where(user => user.HasName)
.Cast<IUserSearchItem>();
}
catch (DirectoryOperationException ex)
{
response = (SearchResponse) ex.Response;
return response.Entries.Cast<SearchResultEntry>()
.Select(entry => entry.Attributes)
.Select(x => GetADUserSearchItemFromADProperties(x, logMessage))
.Where(user => user.HasName)
.Cast<IUserSearchItem>();
}
试试看
{
响应=（搜索响应）con.SendRequest（请求）；
返回response.Entries.Cast（）
.Select（entry=>entry.Attributes）
.Select（x=>GetADUserSearchItemFromADProperties（x，logMessage））
.Where（user=>user.HasName）
.Cast（）；
}
捕获（目录操作例外）
{
响应=（搜索响应）例如响应；
返回response.Entries.Cast（）
.Select（entry=>entry.Attributes）
.Select（x=>GetADUserSearchItemFromADProperties（x，logMessage））
.Where（user=>user.HasName）
.Cast（）；
}
我已经尝试过了，并且得到了预期的结果，我只是有点不安，因为我必须处理异常才能执行该操作。您应该在类似于此的函数中使用cookies。 该函数返回SearchResponse对象的集合，调用方应循环该集合

{
List<SearchResponse> result = new List<SearchResponse>();

searchRequest.Controls.Add(pageRequestControl);
while (true)
{
response = (SearchResponse)connection.SendRequest(searchRequest);
result.Add(response);
pageResponseControl = (PageResultResponseControl)response.Controls[0];
if (pageResponseControl.Cookie.Length == 0)

pageRequestControl.Cookie = pageResponseControl.Cookie;
}
}

return result;
}
private List SearchDirectory（字符串区分名称、字符串searchFilter、System.DirectoryServices.Protocols.SearchScope、参数字符串[]属性列表）
{
列表结果=新列表（）；
SearchResponse=null；
int maxResultsToRequest=100；
尝试
{
PageResultRequestControl pageRequestControl=新的PageResultRequestControl（maxResultsToRequest）；
//用于检索要为后续请求发送的cookie
PageResultResponse控件PageResponse控件；
SearchRequest SearchRequest=新的SearchRequest（区分名称、searchFilter、searchScope、attributeList）；
searchRequest.Controls.Add（pageRequestControl）；
while（true）
{
response=（SearchResponse）connection.SendRequest（searchRequest）；
结果：添加（响应）；
pageResponseControl=（PageResultResponseControl）响应。控件[0]；
if（pageResponseControl.Cookie.Length==0）
打破
pageRequestControl.Cookie=pageResponseControl.Cookie；
}
}
捕获（例外e）

返回结果；
