How to Parse Nested JSON Data into C# Objects using Json.NET?

Using json.net to analyze json

json.net is a popular library to process JSON data in the .NET environment. It provides a convenient way to analyze the JSON string and serialize it into a C#object.

Analysis of JSON

To analyze JSON as an object, you can use the method, where T is the type of object you want to create. For the JSON provided, you can create the following categories:

JsonConvert.DeserializeObject<T> After creating these classes, you can analyze JSON as FOO object:

<code class="language-csharp">public class DisplayFieldName
{
    public string OBJECT_NAME { get; set; }
}

public class NameTypePair
{
    public string Name { get; set; }
    public string Type { get; set; }
}

public class FieldAliases
{
    public NameTypePair OBJECT_NAME { get; set; }
    public NameTypePair OBJECT_TYPE { get; set; }
}

public class PositionType
{
    public string Type { get; set; }
}

public class Reference
{
    public int Id { get; set; }
}

public class Attributes
{
    public string OBJECT_NAME { get; set; }
    public string OBJECT_TYPE { get; set; }
}

public class Position
{
    public int X { get; set; }
    public int Y { get; set; }
}

public class ObjectItem
{
    public Attributes Attributes { get; set; }
    public Position Position { get; set; }
}

public class Foo
{
    public DisplayFieldName DisplayFieldName { get; set; }
    public FieldAliases FieldAliases { get; set; }
    public PositionType PositionType { get; set; }
    public Reference Reference { get; set; }
    public List<ObjectItem> Objects { get; set; }
}</code>

Access the nested attribute

<code class="language-csharp">string json = @"{
    ""displayFieldName"" : ""OBJECT_NAME"", 
    ""fieldAliases"" : {
        ""OBJECT_NAME"" : ""OBJECT_NAME"", 
        ""OBJECT_TYPE"" : ""OBJECT_TYPE""
    }, 
    ""positionType"" : ""point"", 
    ""reference"" : {
        ""id"" : 1111
    }, 
    ""objects"" : [
        {
            ""attributes"" : {
                ""OBJECT_NAME"" : ""test name"", 
                ""OBJECT_TYPE"" : ""test type""
            }, 
            ""position"" : {
                ""x"" : 5, 
                ""y"" : 7
            }
        }
    ]
}";

Foo foo = JsonConvert.DeserializeObject<Foo>(json);</code>

To access the data in the FOO object, you can use attributes and indexes. For example, to obtain the "test name" value from the Objects array, you can use:
