When consuming REST APIs in C# I like to use the Newtonsoft.Json library which is available as a NuGet package.
Start by adding the package to your library. Right-click on your project in the Solution Explorer (if using Visual Studio) and click on “Manage NuGet Packages…”
Search for Json and add Newtonsoft.Json.
Add a reference by typing using Newtonsoft.Json.Linq;
For connecting to the API you can use many options. To keep it simple we’ll use System.Net.WebClient. Ref example code below:
var apiUrl = "https://example.com/api/v1/helloworld"; using WebClient wc = new WebClient(); var jsondata = wc.DownloadString(apiUrl); JArray jsonarray = JArray.Parse(jsondata); foreach (var item in jsonarray) { JObject jsonobject = JObject.Parse(item.ToString()); Debug.WriteLine(jsonobject); }
Another example without looping through the items and using WebClient in another way:
var apiUrl = "https://example.com/api/v1/helloworld"; using (WebClient wc = new WebClient()) { var jsondata = wc.DownloadString(apiUrl); JObject jsonobject = JObject.Parse(jsondata.ToString()); Debug.WriteLine(jsonobject); }
