API Explorer: IFormCollection is considered as KeyValuePairOfStringAndStringValues

[ranouf]

Hi,

I would like to upload multiple file as I wrote here (#1421 (comment)), from what I read on internet (aspnet/Mvc#7719), IEnumerable doesnt work when you want to upload multiple files, to make it work, you need to use IFormCollection.

This is my DTO:

public class SampleDetailsDto
{
    public Guid Id{ get; set; }
    public string Text { get; set; }
    public IFormCollection Images { get; set; }
}

Controller:

[HttpPut]
[Route("{id:guid}")]
public async Task<IActionResult> UpdateAsync([FromRoute]Guid id, [FromForm] SampleDetailsDtodto)
{
    Console.WriteLine(dto.Text); 
    Console.WriteLine(dto.Images.Length);
    return OK();
}

Class generated by NSWAG:

export class SampleDto implements ISampleDto {
    text?: string | undefined;
    image?: KeyValuePairOfStringAndStringValues[] | undefined;
    id?: string | undefined;
}

Maybe there is a reason I ignore? But I think the best way to "translate" it from C# to Typescript could be FileList or File[], what do you think?

Is this also caused by this ASP.NET Core "bug"?
