SODA.NET Build status

A Socrata Open Data API (SODA) client library targeting .NET 4.5 and above.

Getting Started

SODA.NET is available as a NuGet package.

dotnet add package CSM.SodaDotNet

Usage examples

Simple, read-only access

//initialize a new client
//make sure you register for your own app token (
var client = new SodaClient("", "REPLACE_WITH_YOUR_APP_TOKEN");

//read metadata of a dataset using the resource identifier (Socrata 4x4)
var metadata = client.GetMetadata("1234-wxyz");
Console.WriteLine("{0} has {1} views.", metadata.Name, metadata.ViewsCount);

//get a reference to the resource itself
//the result (a Resouce object) is a generic type
//the type parameter represents the underlying rows of the resource
var dataset = client.GetResource<Dictionary<string, object>>("1234-wxyz");

//of course, a custom type can be used as long as it is JSON serializable
var dataset = client.GetResource<MyClass>("1234-wxyz");

//Resource objects read their own data
var allRows = dataset.GetRows();
var first10Rows = dataset.GetRows(10);

//collections of an arbitrary type can be returned
//using SoQL and a fluent query building syntax
var soql = new SoqlQuery().Select("column1", "column2")
                          .Where("something > nothing")

var results = dataset.Query<MyOtherClass>(soql);

SodaClient is also capable of performing write operations

//make sure to provide auth credentials!
var client = 
    new SodaClient("", "AppToken", "", "password");

//Upsert some data serialized as CSV
string csvData = File.ReadAllText("data.csv");
client.Upsert(csvData, SodaDataFormat.CSV, "1234-wxyz");

//Upsert a collection of serializable entities
IEnumerable<MyClass> payload = GetPayloadData();
client.Upsert(payload, "1234-wxyz");

Note: This library supports writing directly to datasets with the Socrata Open Data API. For write operations that use data transformations in the Socrata Data Management Experience (the user interface for creating datasets), use the Socrata Data Management API. For more details on when to use SODA vs the Socrata Data Management API, see the Data Management API documentation


Compilation can be done using Visual Studio Community Edition.

You can also use the .NET CLI:

git clone SODA.NET
dotnet build


NUnit was used to build and run the test projects.

Run tests from the Visual Studio Test Explorer, or using the .NET CLI:

dotnet test
