JToken
In this article we will see how we can manipulate json using CreateReader and CreateWriter methods of JToken object of Newtonsoft library.
CreateReader
//Use JObject and populate the json
JObject oJsonObject = new JObject
{
{ "Employee", "VBAOVERALL" },
{ "Salary", 12000 },
{
"Gender", new JArray
{
"Male",
"Female"
}
}
};
//Instantiate CreateReader
JsonReader reader = oJsonObject.CreateReader();
//Loop through each
while (reader.Read())
{
Console.Write(reader.TokenType);
if (reader.Value != null)
{
Console.Write(" - " + reader.Value);
}
Console.WriteLine();
}
Output
StartObject
PropertyName – Employee
String – VBAOVERALL
PropertyName – Salary
Integer – 12000
PropertyName – Gender
StartArray
String – Male
String – Female
EndArray
EndObject
CreateWriter
JObject oJobject = new JObject
{
{ "SiteName", "VBAOVERALL.COM" },
{ "Grade", "Manager" }
};
JsonWriter writer = oJobject.CreateWriter();
writer.WritePropertyName("Gender");
writer.WriteStartArray();
writer.WriteValue("Male");
writer.WriteValue("Female");
writer.WriteEndArray();
Console.WriteLine(oJobject.ToString());
Output
{
"SiteName": "VBAOVERALL.COM",
"Grade": "Manager",
"Gender": [
"Male",
"Female"
]
}
