Question

如何根据开发者指南的“A.3.4字段搜索请求”使用“类别”？ Bloomberglp.Blpapi.dll来自blpapi_dotnet_3.4.8.1。，由C＃.net开发。

我使用以下代码来获取信息，但它不起作用。

        Service refDataSvc = session.GetService("//blp/refdata");
        Request request = refDataSvc.CreateRequest("ReferenceDataRequest");
        request.Append("securities", "/isin/CNE1000002Q2 HK"); 
        Element element = request.GetElement("include");
        element.SetElement("productType", "Equity");
        element.SetElement("fieldType", "Static");
        Element element1 = element.GetElement("category");
        element1.AppendValue("Ratings");
        element1.AppendValue("Analysis");
        element1.AppendValue("Corporate Actions");
        session.SendRequest(request, null);

我也尝试过其他方法

A）

        Service refDataService = session.GetService("//blp/refdata");
        Request request = refDataService.CreateRequest("ReferenceDataRequest");
        Element securities = request.GetElement("securities");
        securities.AppendValue("IBM US Equity");
        Element fields = request.GetElement("fields");
        fields.AppendValue("PX_LAST");
        Element element1 = fields.GetElement("category");
        element1.AppendValue("Corporate Actions");
        session.SendRequest(request, null);

b）中

        Service refDataService = session.GetService("//blp/refdata");
        Request request = refDataService.CreateRequest("ReferenceDataRequest");
        Element securities = request.GetElement("securities");
        securities.AppendValue("IBM US Equity");
        Element element1 = request.GetElement("category");
        element1.AppendValue("Corporate Actions");
        session.SendRequest(request, null);

两者都不成功。有人可以就此提出建议吗？
