我能从PrincipalSearcher中得到1000多张唱片吗？

Question

我试图让Active Directory中的所有用户使用代码：

PrincipalContext ad = new PrincipalContext(contextType, adserviceName, adContext, ContextOptions.SimpleBind, username, password);
UserPrincipal u = new UserPrincipal(ad) {Name = "*"};
PrincipalSearcher search = new PrincipalSearcher { QueryFilter = u };
foreach (var principal in search.FindAll()) 
{
    //do something 
}

但是它只返回前1000行。如何在不使用DirectorySearcher的情况下检索所有用户。谢谢。

Answer 1

我认为如果不使用DirectorySearcher.，你就无法做到这一点。

代码片段-

// set the PageSize on the underlying DirectorySearcher to get all entries
((DirectorySearcher)search.GetUnderlyingSearcher()).PageSize = 1000;

Answer 2

您需要获取基础DirectorySearcher并在其上设置PageSize属性：

using (PrincipalContext ad = new PrincipalContext(contextType, adserviceName, adContext, ContextOptions.SimpleBind, username, password))
{ 
    UserPrincipal u = new UserPrincipal(ad) {Name = "*"};

    PrincipalSearcher search = new PrincipalSearcher { QueryFilter = u };

    // get the underlying "DirectorySearcher"
    DirectorySearcher ds = search.GetUnderlyingSearcher() as DirectorySearcher;

    if(ds != null)
    {
        // set the PageSize, enabling paged searches
       ds.PageSize = 500;
    }


    foreach (var principal in search.FindAll()) 
    {
        //do something 
    }
}

Answer 3

您可以：

((DirectorySearcher)myPrincipalSearcher.GetUnderlyingSearcher()).SizeLimit = 20;
