因为System.dll中发生SocketException而没有结果 [英] Getting no results because SocketException occurred in System.dll

问题描述

我正在编写一个应用程序，用于检索给定网络上所有计算机的名称和IP地址。这是为了在远程连接到计算机时使用的技术支持。我仍在开发并且只在我自己的网络上进行测试，但是当我运行它时，我没有得到任何结果，这显示在输出中。

I am writing an application that retrieves the names and IP addresses of all computers on a given network. This is for technical support to use while remoting into a computer. I'm still developing and only testing on my own network, but when I run it I get no results and this shows up in the output.

A first chance exception of type 'System.Net.Sockets.SocketException' occurred in System.dll

我的代码如下：

public List<NetworkComputer> getComputers( string domain )
        {
            List<NetworkComputer> computers = new List<NetworkComputer>();

            DirectoryEntry entry = new DirectoryEntry( domain );
            DirectorySearcher searcher = new DirectorySearcher( entry );
            searcher.Filter = ("(objectClass=computer)");
            searcher.SizeLimit = int.MaxValue;
            searcher.PageSize = int.MaxValue;

            foreach( SearchResult result in searcher.FindAll() )
            {
                if( result.GetDirectoryEntry().Name.StartsWith( "CN=" ) )
                {
                    IPAddress ipAddress = null;

                    ipAddress = Dns.GetHostAddresses( result.GetDirectoryEntry().Name.Remove( 0, "CN=".Length ) )[0];

                    computers.Add( new NetworkComputer( result.GetDirectoryEntry().Name.Remove( 0, "CN=".Length ), ipAddress ) );
                }
            }

            return computers;
        }
    }
}

如果我在不尝试的情况下运行它获取IP地址我得到一个没有问题的所有计算机的列表。这是造成我问题的IP地址。

If I run it without attempting to get IP addresses I get a list of all computers with no issues. It's the IP addresses that are causing me problems.
