Network Programming in .NET

The Bing Image search based on the DataMarket service by Microsoft is closing down, and it is moving to cognitive services. This means that if you have code that uses an endpoint like this;

https://api.datamarket.azure.com/Bing/Search/v1/Image …

It needs to be changed to code like this:

https://api.cognitive.microsoft.com/bing/v5.0/images/search …

And your quote is reduced to 1,000 per month… 😦

Here’s some code I’ve written in C# to do a basic image search

public static List<String> GetImages(string searchText)
{
var strUrl = “https://api.cognitive.microsoft.com/bing/v5.0/images/search?q=&#8221; + searchText + “&count=1000”;
var wc = new WebClient();
wc.Headers[“Ocp-Apim-Subscription-Key”] = “xxxxxxxxxxx”;
var strJson = wc.DownloadString(strUrl);
var bing = JavascriptDeserialize<BingSearchObject>(strJson);
var lResults = new List<string>();
foreach (var result in bing.value)
{
var qs = HttpUtility.ParseQueryString(result.contentUrl);
lResults.Add(qs[“r”]);

}
return lResults;
}

Where “BingSearchObject” is defined as:
