调用LdapConnetion.Disconnect时的PlatformNotSupportedException

Question

一切似乎都运行得很好(除了检索特定属性应该比遍历所有现有属性要容易得多--不确定为什么它是这样设计的)，但是当我尝试断开连接时，我得到了以下结果：

PlatformNotSupportedException:此平台不支持线程中止。

代码与Novell文档中的代码几乎完全相同，只是我试图检索两个特定的属性(名称和登录时间)：

var users = new List();

// Creating an LdapConnection instance 
LdapConnection ldapConn= new LdapConnection();

//Connect function will create a socket connection to the server
ldapConn.Connect("DOMAIN.com",389);

//Bind function will Bind the user object Credentials to the Server
ldapConn.Bind("DOMAIN\\_Bassi","password");

// Searches in the Marketing container and return all child entries just below this
//container i.e. Single level search
LdapSearchResults lsc=ldapConn.Search("OU=Users,OU=MCS,OU=AU,OU=COMPANY,DC=DOMAIN,DC=com",
                LdapConnection.SCOPE_ONE,
                "objectClass=*",
                null,
                false);

while (lsc.hasMore())
{
    var user = new User();

    LdapEntry nextEntry = null;
    try 
    {
        nextEntry = lsc.next();
    }
    catch(LdapException e) 
    {
        Console.WriteLine("Error: " + e.LdapErrorMessage);
        // Exception is thrown, go for next entry
        continue;
    }
    Console.WriteLine("\n" + nextEntry.DN);

    LdapAttributeSet attributeSet = nextEntry.getAttributeSet();
    System.Collections.IEnumerator ienum =  attributeSet.GetEnumerator();

    var atts = attributeSet.ToArray().ToList();

    while(ienum.MoveNext())
    {
        LdapAttribute attribute=(LdapAttribute)ienum.Current;
        if(attribute.Name == "sAMAccountName")
        {
            user.UserName = attribute.StringValue;
        } 
        else if(attribute.Name == "lastLogonTimestamp")
        {
            user.LastLogon = DateTime.FromFileTime(long.Parse(attribute.StringValue));
        }
    }

    users.Add(user);
}

ldapConn.Disconnect();

一旦Disconnect被调用时，我得到了错误。

还有没有其他人经历过这种情况，或者知道可能出了什么问题？

Answer 1

Novell开发人员已经提出了新版本Novell.Directory.Ldap.NETStandard

它似乎与DotNet Core2.0完全兼容。我已经将我的项目引用更改为Novell.Directory.Ldap.NETStandard 3.0.0版本，现在它工作得很好。

相同的命令行是：

Install-Package Novell.Directory.Ldap.NETStandard -Version 3.0.0-beta4

Answer 2

它抛出此错误的原因是Thread.Abort()在.NET核心中不受支持。需要更新库以使用不同的机制(我相信CancellationToken是推荐的方法)。
