使用 Google CustomsearchService 在网络上搜索图片

Question

我需要一点帮助。当我按原样搜索网络但要搜索图像时，以下代码可以完美运行

        const string apiKey = "xxxx";
        const string searchEngineId = "xxxx";
        const string query = "apple";
        var customSearchService = new CustomsearchService(new BaseClientService.Initializer { ApiKey = apiKey });
        var listRequest = customSearchService.Cse.List(query);
        listRequest.Cx = searchEngineId;
        listRequest.Num = 1;
        //listRequest.Fields = "items(image(contextLink,thumbnailLink),link)";
        listRequest.SearchType = CseResource.ListRequest.SearchTypeEnum.Image;
        listRequest.Start = 1;

        var search = listRequest.Execute();

        foreach (var result in search.Items)
        {
            Debug.WriteLine(string.Format("Title: {0}", result.Title));
            Debug.WriteLine(string.Format("Link: {0}", result.Link));
        }

当SearchType 是Image 时，search.Items 会产生null。

对不起。我忘了在 Google CSE 页面上打开图像搜索。现在它工作正常。
