Bing API“.Count”属性不起作用？

Question

我一直在尝试使用Bing API恢复20张图片的结果。这是代码：

SearchRequest request = new SearchRequest();
request.AppId = APPID;
request.Query = HttpUtility.HtmlEncode(searchQuery);
request.Sources = new SourceType[] { SourceType.Image };
request.Image = new ImageRequest();
request.Image.Count = 20;
request.Image.Filters = new string[1] { "Size:Medium" };

现在这里的一切都有效，包括Image.Filters属性。不是Count属性。有没有已知的错误，或者我在这里遗漏了什么？

我不确定这一点，但我认为您缺少设置CountSpecified属性。试试这个

request.Image = new ImageRequest();
request.Image.Offset = 0;
request.Image.Count = 20;
request.Image.CountSpecified = true;
request.Image.Filters = new string[1] { "Size:Medium" };
