You can try out the source generator by using the latest build of the System.Text.Json NuGet package. System.Text.Json was released last year and since it's integrated into ASP.NET Core 3, I thought we should briefly compare it to the most downloaded NuGet package around, Newtonsoft.Json.. JsonStringEnumMemberConverter from Macross.Json.Extensions appears to provide this functionality when the enum is decorated with [EnumMember(Value = "custom name")] attributes; install the package Macross.Json.Extensions and then do: [JsonConverter(typeof(System.Text.Json.Serialization.JsonStringEnumMemberConverter))] // … The last bits about entryModel and json.GetRawText() are from my code. It was designed with performance in mind, that should be its main selling point over Newtonsoft.Json. For me it is important to keep the nested JSON object as original as possible. First, let me thank Newtonsoft, which has close to a billion dowloads, for making JSON processing possible before Microsoft and for shaping STJ. There is also a popular third-party library called Json.NET.. System.Text.Json. The code above writes a null value if the AggregationContainer is null. For example, we can create a generic number to string converter: That reference pulls in System.Text.Json from preview.3 which seems to have different logic. List results = JsonConvert.DeserializeObject> (jsonString); Best Regards, Timon. For example, we can create a generic number to string converter: To review, open the file in an editor that reveals hidden Unicode characters. value T Namespace: Newtonsoft.Json Step 3 : Copy the retuned C# classes from the second editor and deserialize using the 'Root' class. AFAIK, System.Text.Json was never meant to be a 1:1 replacement for Newtonsoft.Json.

Create a StringConverter for System.Text.Json for JSON Serialization. Starting with v0.8.2, LambdaSharp uses System.Text.Json v5.0 instead of Newtonsoft.Json for JSON serialization of built-in types. I understand that the System.Text.Json is still in development. For more information, see Reuse JsonSerializerOptions instances.. At this point I decided to look into Github to find System.Text.Json.JsonConverter implementation and see what is going on. I am in the process of migrating from Newtonsoft.Json to System.Text.Json (STJ). Previously, when using Newtonsoft.Json, I had a custom converter that would determine how to deserialize based on whether the JToken.Type was JTokenType.Object (detecting that the value was likely another instance of the same class). Serialize and Deserialize fields. Here is what I did: 1) Place your JSON sample above in a text file 2) Make a file with your class and a routine to read file and deserialize JSON into a List public class RecordDetail { public int TransactionId { get; set; } public string CName { get; set; } public string TDate { get; set; } public string BDate { get; set; } public string Initials { get; set; } … Int32Converter for System.Text.Json.
