Answer by ADM-IT for Serialize an object to string

Serialize and Deserialize XML/JSON (SerializationHelper.cs) (You can use Newtonsoft.Json Nuget Package for JSON serialization):

using Newtonsoft.Json;using System.IO;using System.Xml.Serialization;namespace MyProject.Helpers{    public static class SerializationHelper    {        public static T DeserializeXml<T>(this string toDeserialize)        {            XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));            using (StringReader textReader = new StringReader(toDeserialize))            {                return (T)xmlSerializer.Deserialize(textReader);            }        }        public static string SerializeXml<T>(this T toSerialize)        {            XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));            using (StringWriter textWriter = new StringWriter())            {                xmlSerializer.Serialize(textWriter, toSerialize);                return textWriter.ToString();            }        }        public static T DeserializeJson<T>(this string toDeserialize)        {            return JsonConvert.DeserializeObject<T>(toDeserialize);        }        public static string SerializeJson<T>(this T toSerialize)        {            return JsonConvert.SerializeObject(toSerialize);        }    }}

Alternatively you can use System.Text.Json Nuget Package instead for Json serialization:

using System.Text.Json;...public static T DeserializeJson<T>(this string toDeserialize, JsonSerializerOptions options = null){    return JsonSerializer.Deserialize<T>(toDeserialize, options);}public static string SerializeJson<T>(this T toSerialize, JsonSerializerOptions options = null){    return JsonSerializer.Serialize<T>(toSerialize, options);}
