调用时发生 PlatformNotSupportedException LdapConnetion.Disconnect

Question

一切似乎都工作正常（除了检索特定属性应该比遍历所有现有属性更容易的事实 - 不确定为什么这样设计），但是当我尝试断开连接时我得到

PlatformNotSupportedException: Thread abort is not supported on this platform.

该代码与从 Novell 文档中获取的代码几乎完全相同，除了我试图仅检索 2 个特定属性（名称和登录时间）之外：

var users = new List<User>();

// 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();

一旦调用 Disconnect，我就会收到错误消息。

有没有其他人遇到过这种情况或知道可能出了什么问题？

Answer 1

它抛出此错误的原因是因为.NET Core 不支持Thread.Abort()。该库将需要更新以使用不同的机制（我相信 CancellationToken 是推荐的方法）

Answer 2

Novell 开发人员提出了 new version of Novell.Directory.Ldap.NETStandard 似乎与 DotNet Core 2.0 完全兼容。我已将项目参考更改为 Novell.Directory.Ldap.NETStandard 3.0.0 版本，现在运行正常。

相同的命令行是：

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