OData enum values use string values

[CupcakeThief]

OData/WebApi#1785

The default conversion for enums in OData is to use the string values...

Need to add
new JsonStringEnumConverter(null)
to AddOdataSupport converters.

Version 2.0.0 solves this issue

Hmm I am still getting the same type conversion error, did this fix deffo make it into 2.0.0?

[gustavnavar]

Yes

The JSON value could not be converted to Blackbot.Model.Prospects.ProspectStatus. Path: $.value[0].Status | LineNumber: 0 | BytePositionInLine: 324.

{"@odata.context":"https://localhost:5001/odata/$metadata#Prospects","@odata.count":5765,"value":[{"Id":"2019092517303934_30_min_EUR-GBP","ChartName":"m30","Symbol":"EUR/GBP","MotherStartDateTime":"2019-09-25T17:30:00+01:00","MotherHigh":0.000000,"MotherLow":0.000000,"ChildEndDateTime":"0001-01-01T00:00:00Z","Status":"Won"

I'll have a bit more of a poke about this evening

Have simplified my test page.

shared:

    public enum MyEnum
    {
        Foo,
        Bar,
        Baz
    }
    public record MyDTO(int Id, MyEnum Enum);

controller

    public class FooController : Controller
    {
        [EnableQuery]
        public IQueryable<MyDTO> Get()
        {
            return new[]
            {
                new MyDTO(1, MyEnum.Bar),
                new MyDTO(2, MyEnum.Baz)
            }.AsQueryable();
        }
    }

page:

    private CGrid<MyDTO> _grid;
    private Task _task;

    Action<IGridColumnCollection<MyDTO>> columns = c =>
    {
        c.Add(p => p.Id);
        c.Add(p => p.Enum);
    };

    protected override async Task OnParametersSetAsync()
    {
        string url = NavigationManager.BaseUri + "odata/foo";
        var query = new QueryDictionary<StringValues>();

        var client = new GridODataClient<MyDTO>(Client, url, query, false, "ordersGrid", columns, 10)
        {
        };
        _grid = client.Grid;

        // Set new items to grid
        _task = client.UpdateGrid();
        await _task;
    }

```

gives result

The JSON value could not be converted to Blackbot.Blazor.Shared.MyDTO. Path: $.value[0].Enum | LineNumber: 0 | BytePositionInLine: 109.

aha..
GridBlazor\CGrid.cs
l.1150 (+1111)

ODataDTO<T> response = await HttpClient.GetFromJsonAsync<ODataDTO<T>>(Url + allParameters);

It's not customising the deserialiser.

Might need adding here, too?
ODataService.cs

public async Task<T> Get(params object[] keys)
{
    string url = GetUrl(_grid, _url, keys);
    return await _httpClient.GetFromJsonAsync<T>(url);
}
