在.NET核心3.1上使用NetSuite WSDL对所有字段返回null的customLabel

using System;
using System.ServiceModel;
using NetSuite.com.netsuite.webservices;

public class NetSuiteClient
{
    private readonly SuiteTalkPortTypeClient _client;

    public NetSuiteClient(string endpointUrl, string username, string password)
    {
        var binding = new BasicHttpBinding();
        var endpointAddress = new EndpointAddress(endpointUrl);

        _client = new SuiteTalkPortTypeClient(binding, endpointAddress);
        var credentials = new ServiceCredentials();
        credentials.UserName.UserName = username;
        credentials.UserName.Password = password;
        _client.ChannelFactory.Endpoint.Behaviors.Add(credentials);
    }

    public void GetCustomRecords()
    {
        var search = new CustomRecordSearchAdvanced();
        // 设置搜索条件...

        var response = _client.search(search);

        if (response.status.isSuccess)
        {
            foreach (var record in response.searchResult.recordList)
            {
                if (record is CustomRecord customRecord)
                {
                    // 尝试访问customLabel字段
                    var customLabel = customRecord.customFieldList?.Find(cf => cf.scriptId == "custrecord_customlabel")?.value;
                    Console.WriteLine($"Custom Label: {customLabel}");
                }
            }
        }
        else
        {
            Console.WriteLine("Search failed: " + response.status.statusDetail);
        }
    }
}
