Neo4j驱动程序C#展开对象列表

我正在研究如何将对象列表（内存中）展开到Neo4J4.0中。下面是我以前使用Neo4jClient nuget时所做的，但我必须改用Neo4j.Driver nuget

Neo4jClient（旧版）

Neo4j驱动程序（到目前为止已完成）

遗憾的是，Neo4j驱动程序非常简单——您需要手工构建Cypher查询，在需要的地方引用参数，然后将这些参数传递到查询中

var session = driver.AsyncSession(o => o.WithDatabase("neo4j"));
try
{
    towns = towns.OrderBy(tt => tt.Id).ToList();
    foreach (var t in towns.Split(5000))
    {
        Console.WriteLine($"Saving {t.Count:N0} of {town.Count:N0} Towns...");

        // Just return the town name - in your case, you'd MERGE or whatever, this is 
        // just an example
        var query = new Query("UNWIND {towns} AS town RETURN town", new Dictionary<string, object>
        {
            { "towns", towns }
        });

        var result = await session.RunAsync(query);
    }
}
catch (Exception ex)
{
    string error = $"ERROR (ADD TOWNS): {ex.ToString()}";
    Console.WriteLine(error);
}
finally
{
    await session.CloseAsync();
}

var session=driver.AsyncSession（o=>o.WithDatabase（“neo4j”）；
尝试
{
towns=towns.OrderBy（tt=>tt.Id.ToList（）；
foreach（城镇中的var t.分割（5000））
{
Console.WriteLine（$“保存{town.Count:N0}个城镇的{t.Count:N0}…”）；
//只需返回城镇名称-在您的情况下，您可以合并或其他方式，这是
//只是一个例子
var query=新查询（“将{towns}作为城镇返回城镇展开”，新字典
{
{“城镇”，城镇}
});
var result=wait session.RunAsync（查询）；
}
}
捕获（例外情况除外）
{
字符串错误=$“错误（添加城镇）：{ex.ToString（）}”；
控制台写入线（错误）；
}
最后
{
等待会话。CloseAsync（）；
}

var session = driver.AsyncSession(o => o.WithDatabase("neo4j"));
        try
        {
            towns = towns.OrderBy(tt => tt.Id).ToList();
            foreach (var t in towns.Split(5000))
            {
                    Console.WriteLine($"Saving {t.Count:N0} of {town.Count:N0} Towns...");    
        **//STUCK HERE DOING UNWIND**  
            }
        }
        catch (Exception ex)
        {
            string error = $"ERROR (ADD TOWNS): {ex.ToString()}";           
            Console.WriteLine(error);
        }
        finally
        {
            await session.CloseAsync();
        }

var session = driver.AsyncSession(o => o.WithDatabase("neo4j"));
try
{
    towns = towns.OrderBy(tt => tt.Id).ToList();
    foreach (var t in towns.Split(5000))
    {
        Console.WriteLine($"Saving {t.Count:N0} of {town.Count:N0} Towns...");

        // Just return the town name - in your case, you'd MERGE or whatever, this is 
        // just an example
        var query = new Query("UNWIND {towns} AS town RETURN town", new Dictionary<string, object>
        {
            { "towns", towns }
        });

        var result = await session.RunAsync(query);
    }
}
catch (Exception ex)
{
    string error = $"ERROR (ADD TOWNS): {ex.ToString()}";
    Console.WriteLine(error);
}
finally
{
    await session.CloseAsync();
