Contentstack - .Net Delivery SDK

.NET SDK for Contentstack's Content Delivery API

Contentstack is a headless CMS with an API-first approach. It is a CMS that developers can use to build powerful cross-platform applications in their favorite languages. Build your application frontend, and Contentstack will take care of the rest. Read More.

Prerequisites

To get started with C#, you will need:

.Net platform
IDE (Visual Studio)
NuGet.

SDK installation and setup

The .Net SDK provided by contentstack.io is available for Xamarin, Windows Phone and legacy .Net applications. You can integrate contentstack with your application by following these steps.

Open the terminal and install the contentstack module via 'Package Manager' command

PM> Install-Package contentstack.csharp

And via ‘.Net CLI’

dotnet add package contentstack.csharp

To use the module in your application, you need to first Add Namespace to your class

using Contentstack.Core; // ContentstackClient
using Contentstack.Core.Models; // Stack, Query, Entry, Asset, ContentType, ContentstackCollection
using Contentstack.Core.Configuration; // ContentstackOptions

Quickstart in 5 mins

Initialize SDK

You will need to specify the API key, Access token, and Environment Name of your stack to initialize the SDK:

// Initialize the Contentstack 
ContentstackClient client = new ContentstackClient("api_key", "delivery_token", "enviroment_name");

or:

ContentstackOptions options = new ContentstackOptions()
{
	ApiKey = "<api_key>",
	DeliveryToken = "<access_token>",
	Environment = "<environment>"
}
ContentstackClient client = new ContentstackClient(options);

Once you have initialized the SDK, you can start getting content in your app
For Setting the European Region:

Refer the below code if you want to use European region.

ContentstackOptions options = new ContentstackOptions()
{
	ApiKey = "<api_key>",
	DeliveryToken = "<delivery_token>",
	Environment = "<environment>",
	Region = ContentstackRegion.EU
}
ContentstackClient client = new ContentstackClient(options);

Once you have initialized the SDK, you can start getting content in your app.

For Setting the branch:

If you want to initialize SDK in a particular branch use the code given below:

ContentstackOptions options = new ContentstackOptions() 
{
	ApiKey = "<api_key>",
	DeliveryToken = "<delivery_token>",
	Environment = "<environment>",
	Branch = "<branch>"
};
ContentstackClient client = new ContentstackClient(options);

Basic Queries

Get a Single Entry

To retrieve a single entry from a content type, use the code snippet given below:

ContentstackClient client = new ContentstackClient("api_key", "delivery_token", "enviroment_name");
Entry entry = client.ContentType("product").Entry("entry_uid");
entry.Fetch<Product>().ContinueWith((t) => { 
    if (!t.IsFaulted) { 
        Console.WriteLine("entry:" + t.Result);  
    } 
});

Get Multiple Entries

To retrieve multiple entries of a particular content type, use the code snippet given below:

ContentstackClient client = new ContentstackClient("api_key", "delivery_token", "enviroment_name");
Query query = client.ContentType("product").Query(); 
query.Where("title", "welcome"); 
query.IncludeSchema(); 
query.IncludeCount(); 
query.ToJSON(); 
query.Find<Product>().ContinueWith((t) => { 
    if (!t.IsFaulted) { 
        ContentstackCollection<Product> result = t.Result; 
        Console.WriteLine("result" + result.items); 
    } 
});

Paginating Responses

In a single instance, the Get Multiple Entries query will retrieve only the first 100 items of the specified content type. You can paginate and retrieve the rest of the items in batches using the skip and limit parameters in subsequent requests.

ContentstackClient client = new ContentstackClient("api_key", "delivery_token", "enviroment_name");
Query query = client.ContentType("blog").Query();
query.Skip(20);
query.Limit(20); 
query.Find<Blog>().ContinueWith((t) => { 
    if (!t.IsFaulted) { 
         ContentstackCollection<Blog> result = t.Result; 
         Console.WriteLine("result" + result); 
    } 
});
