OptimizelyJSON for the C# SDK

3 min

Since static-typed languages lack native support for JSON, the C# SDK uses the OptimizelyJson object to retrieve JSON in a flexible way.

Version

SDK v3.5 and higher

Methods

You can access JSON representations with the following methods:

Method	Parameters	Description
`ToString`	none	Returns a string representation of the JSON object
`ToDictionary`	none	Returns a dictionary representation of the JSON object: `(Dictionary)`
`GetValue`	`string jsonPath`	Returns a specified schema object (`T`) with the key/value pair of the JSON key you pass to this method. If JSON key is null or empty, it populates your schema object with all JSON key/value pairs. You can retrieve information for a nested member of the JSON data structure by using flattened JSON dot notation.\ For example, if you want to access the key `nestedField2` in `{field1: {nestedField2: "blah"}}`, you can call `GetValue` with the parameter `"field1.nestedField2"`.

The OptimizelyJson object is defined as follows:

public class OptimizelyJson
{
    public string ToString();

    public Dictionary<string, object> ToDictionary();

    public T GetValue<T>(string jsonPath);
}

Examples

You can use OptimizelyJson, to:

Get a JSON string by calling the ToString method, or

Retrieve a specified schema from the OptimizelyJson object by calling the GetValue method.

The following example shows how to use an OptimizelyJson object to populate a schema object you declare.

//declare a schema object into which you want to unmarshal OptimizelyJson content:
public class ExampleSubObject
{
    public string? Field;
}

public class ExampleObject
{
    public int? Field1;
    public double? Field2;
    public string? Field3;
    public ExampleSubObject? Field4;
}

var datafileJsonString =
    "{\"field1\": 1, \"field2\": 2.0, \"field3\": \"3\", \"field4\": {\"field\": \"4\"}}";
var optimizelyJson =
    new OptimizelyJSON(datafileJsonString, new DefaultErrorHandler(), new DefaultLogger());

// Parse all json key/value pairs into your schema
var exampleObject = optimizelyJson.GetValue<ExampleObject>(null);

// Parse the specified key/value pair with an integer value 
int field1 = optimizelyJson.GetValue<int>("field1");

// Parse the specified key/value pair with a string value
var exampleSubObject = optimizelyJson.GetValue<ExampleSubObject>("field4");
