c# how to convert string to json

Comment

you can use the JsonConvert class provided by the Newtonsoft.Json package. Here's an example:

using Newtonsoft.Json;

string jsonString = "{\"name\": \"John\", \"age\": 30, \"city\": \"New York\"}";

// Convert the string to a JSON object
JObject json = JObject.Parse(jsonString);

// Or, you can also use the JsonConvert class to deserialize the string into a JSON object
JObject json = JsonConvert.DeserializeObject<JObject>(jsonString);

//the JObject class represents a JSON object, and Parse and DeserializeObject methods
//are used to convert the string to a JSON object. Once you have a JSON object,
//you can access its properties using the [] operator:

//c#
string name = (string)json["name"];
int age = (int)json["age"];
string city = (string)json["city"];
