Getting started with Simple.OData.Client
The easiest way to start using Simple.OData.Client is to install it’s Nuget package. In Visual Studio open Package Manager console and type the following:
Install-Package Simple.OData.Client
You will see output similar to this:
Successfully installed 'Simple.OData.Client 5.4.0'.
Successfully added 'Simple.OData.Client 5.4.0' to SimpleODataTest.
In the source file where you will be using OData provider import namespaces:
using Simple.OData.Client;
Create an instance of ODataClient by passing an OData service URL:
var client = new ODataClient("http://packages.nuget.org/v1/FeedService.svc/");
Now you can access data from the OData server using either basic or fluent API.
Example of basic API syntax:
var packages = await client
.FindEntriesAsync("Packages?$filter=Title eq 'Simple.OData.Client'");
foreach (var package in packages)
{
Console.WriteLine(package["Title"]);
}
Example of dynamic fluent API syntax:
var x = ODataDynamic.Expression;
IEnumerable<dynamic> packages = await client
.For(x.Packages)
.Filter(x.Title == "Simple.OData.Client")
.FindEntriesAsync();
foreach (var package in packages)
{
Console.WriteLine(package.Title);
}
Example of typed fluent API syntax (assuming there is a class Package defined):
var packages = await client
.For<Package>()
.Filter(x => x.Title == "Simple.OData.Client")
.FindEntriesAsync();
foreach (var package in packages)
{
Console.WriteLine(package.Title);
}
Note that the examples above refer to the OData collection as “Package” or “Packages”. Simple.OData.Client has a built-in English word pluralizer that can handle both singular and plural forms.
