About

System.Net.ServerSentEvents provides the SseParser type, which exposes factory methods for creating parsers for the events in a stream of server-sent events (SSE).

Key Features

How to Use

Asynchronously parsing event contents as strings

using HttpClient client = new();
using Stream stream = await client.GetStreamAsync("https://localhost:12345/sse");
await foreach (SseItem<string> item in SseParser.Create(stream).EnumerateAsync())
{
    Console.WriteLine(item.Data);
}

Synchronously parsing event contents as JSON

MemoryStream stream = new(data);
foreach (SseItem<Book> item in SseParser.Create(stream, (eventType, bytes) => JsonSerializer.Deserialize<Book>(bytes)).Enumerate())
{
    Console.WriteLine(item.Data.Author);
}
