Upload Image c# asp.netcore.mvc

Recommended Posts


Boa noite, estou a tentar dar upload de uma imagem e aparece-me sempre este erro:

NullReferenceException: Object reference not set to an instance of an object.

var caminho = Path.Combine(he.WebRootPath + "/ImageFiles",


O código é este:

    public async Task<IActionResult> Create([Bind("Vinhoid,Nome,Ano,Teoralcool,Produtorid,Tipoid,Regiaoid,Datacriacao,Localimagem,Garrafid,Descricao,Preco,Stock")] VinhoDistribuicao vinhoDistribuicao, IFormFile Localimagem)
        if (HttpContext.Session.GetString("TipoUtilizador") == "Garrafeira")

            if (ModelState.IsValid)
               if (_context.Vinho.Any(x => x.Ano == vinhoDistribuicao.Ano && x.Nome == vinhoDistribuicao.Nome && x.Tipoid == vinhoDistribuicao.Tipoid) == false)


                    var caminho = Path.Combine(he.WebRootPath + "/ImageFiles",

                    FileStream fileStream = new FileStream(caminho, FileMode.Create);




@model Lab4_Vinhos6.Models.VinhoDistribuicao
<div class="form-group">
                <label asp-for="Localimagem" class="control-label"></label>
                <input asp-for="Localimagem" type="file" accept=".png, .jpg" class="form-control" value="" />

                <span asp-validation-for="Localimagem" class="text-danger"></span>


Alguem me consegue ajudar?
