❔ How do i enumarate this?

Stream responseStream = await response.Content.ReadAsStreamAsync().ConfigureAwait(false);
var sales = JsonSerializer.DeserializeAsyncEnumerable<Sales>(
    responseStream,
    new JsonSerializerOptions
    {
        DefaultBufferSize = 16384

    });

Stream responseStream = await response.Content.ReadAsStreamAsync().ConfigureAwait(false);
var sales = JsonSerializer.DeserializeAsyncEnumerable<Sales>(
    responseStream,
    new JsonSerializerOptions
    {
        DefaultBufferSize = 16384

    });

Why is foreach not possible? fluffyFoxThink

what is "this" referring to? The sales object? A property of sales? If you want to enumerate over sales, then you have to implement IEnumerable<>

DeserializeAsyncEnumerable returns an IAsyncEnumerable according to https://docs.microsoft.com/en-us/dotnet/api/system.text.json.jsonserializer.deserializeasyncenumerable?view=net-7.0

JsonSerializer.DeserializeAsyncEnumerable Method (System.Text.Json)

Wraps the UTF-8 encoded text into an IAsyncEnumerable that can be used to deserialize root-level JSON arrays in a streaming manner.

So to enumerate that, you need to use await foreach

await foreach (var sale in sales)
{
...
}

await foreach (var sale in sales)
{
...
}
