using Newtonsoft.Json; using System; string json = "{\"date\":\"2022-03-15T15:30:00Z\"}"; JsonTextReader reader = new JsonTextReader(new StringReader(json)); while (reader.Read()) { if (reader.TokenType == JsonToken.PropertyName && reader.Value.Equals("date")) { reader.Read(); DateTime date = reader.ReadAsDateTime().Value; Console.WriteLine(date.ToString()); } }In this example, we have a JSON string that contains a date property. We use a JsonTextReader object to read the JSON data and check if the current token is a property with the name "date". If it is, we call the ReadAsDateTime() method to read the date value and convert it to a DateTime object. Finally, we print the DateTime object to the console. The package library used in this example is Newtonsoft.Json which is a popular JSON framework for .NET.
