c# - 在 C# 中读取 SOAP 数组

Question

我正在使用来自第三方网站的网络服务。我在 wsdl 文件中有名为 GetItemAvailable 的类型和方法。当我使用并执行该服务时，它返回一个 SOAP 数组(在 wsdl 中定义为 ItemsArray)。问题是，我不确定需要使用什么类型来获取信息。这是我的代码:

GetItemAvailable.GetItemAvailable gia = new GetItemAvailable.GetItemAvailable();
ItemsArray ia = new ItemsArray();
ia = (gia.CallGetItemAvailable("1088507721", "9780842387491"));
string sttest = ia.id[1].ToString();

错误总是说 ia.id 为 null

我做错了什么？我对 SOAP 不是很熟悉。这是 wsdl:

Answer 1

这不应该是

//string sttest = ia.id[1].ToString();
string sttest = ia[0].item_id;
