C# Class Microsoft.WindowsAzure.MobileServices.JsonExtensions

Helpful extensions that make it easier to manipulate JSON values.

Nulls propagate through calls so for example, given a JSON object like { 'typeInfo': { 'bar' : 2 } }, you could just write obj.Get("typeInfo").Get("bar").AsInteger() to get the value 2. Given a JSON object like { 'baz': 2 }, you could write obj.Get("typeInfo").Get("bar").AsInteger() to get the value null.

Public Methods

Method	Description
Append ( this array, JToken value ) : Newtonsoft.Json.Linq.JArray	Add an element to a JSON array.
AsArray ( this value ) : Newtonsoft.Json.Linq.JArray	Convert a JSON value into an array, returning null if it's unable.
AsBool ( this value ) : bool?	Convert a JSON value into a bool, returning null if it's unable.
AsInteger ( this value ) : int?	Convert a JSON value into an int, returning null if it's unable.
AsNumber ( this value ) : double?	Convert a JSON value into a double, returning null if it's unable.
AsObject ( this value ) : Newtonsoft.Json.Linq.JObject	Convert a JSON value into an object, returning null if it's unable.
AsString ( this value ) : string	Convert a JSON value into a string, returning null if it's unable.
Get ( this value, string name ) : JToken	Gets a named value from an object.
GetPropertyValues ( this value ) : JToken>>.IEnumerable	Enumerate the member name/value pairs of a JSON object.
IsNull ( this value ) : bool	Determine if the value represents null.
Null ( ) : JToken	Get a null JSON value (that when serialized will stay null rather than not being written out).
Set ( this obj, string name, JToken value ) : JContainer	Set a named value on an object and return that object so multiple calls can be chained.
Set ( this obj, string name, bool value ) : JContainer	Set a named value on an object and return that object so multiple calls can be chained.
Set ( this obj, string name, double value ) : JContainer	Set a named value on an object and return that object so multiple calls can be chained.
Set ( this obj, string name, int value ) : JContainer	Set a named value on an object and return that object so multiple calls can be chained.
Set ( this obj, string name, string value ) : JContainer	Set a named value on an object and return that object so multiple calls can be chained.
TryConvert ( this value, object &propertyValue ) : bool	Try to convert a value to a CLR object.
TrySet ( this obj, string name, object value ) : bool	Set a named value on an object of any type. Unlike the other set overloads, this will attempt to convert arbitrary CLR values into the correct JSON types.
