C#: Bing-Search API

In this tutorial, let's talk about how to use Bing-Search API in C#.

Steps

1. Bing Account

First, create a Bing account at https://azure.microsoft.com/en-us/services/cognitive-services/search/ to use Bing services.

Bing services have 4 parts:  

1. Bing - Web search API,
2. Bing - Image search API,
3. Bing - Video search API,
4. Bing - News search API

Bing - Web search API:

• q is a string where the data comes from textbox.
• count is total number of items.
• offset is a parameter that specifies the first entry to return from a collection.
• safeSearch is the safe search level of the results

public async Task<string> GetDataByWebSearchAsync(string q, string count, int offset, string mkt, string safeSearch)
 {
 var client = new HttpClient();
 var queryString = new Dictionary<string, string>();
 
 //request headers
 client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", "<Your key>");
 
 //request parameters
 queryString.Add("q", q);
 queryString.Add("count", count);
 queryString.Add("offset", offset.ToString());
 queryString.Add("mkt", mkt);
 queryString.Add("safesearch", safeSearch);
 
 var uri = "https://bingapis.azure-api.net/api/v5/search/?"
 + "q=" + queryString["q"]
 + "&count=" + queryString["count"]
 + "&offset=" + queryString["offset"]
 + "&mkt=" + queryString["mkt"]
 + "&safesearch=" + queryString["safesearch"];
 
 var response = await client.GetAsync(uri);
 
 return await response.Content.ReadAsStringAsync();
 }

News, Image, Video are the same as Web. Just replace the URI.
