将ASP.NET MVC Razor表单转换为EF创建带有文件上传的表单

Question

I've found numerous simple examples of uploading a file using an MVC Razor view and associated controller method but nine that include paying an EF model as well as the file back to the controller. Can anyone help with resources they have or have found?

Answer 1

Include a property in your view model:

class MyViewModel {
    public HttpPostedFileBase MyFile { get; set; }
    //other properties
}

Add the file input to your form:

<input type="file" name="myFile" />

Then the file will come in through your model:

public ActionResult Create(MyViewModel model) {

    //model.MyFile will be myFile
}

Answer 2

 public ActionResult SomeControllerFunction(EFModel model, HttpPostedFileBase ImageFile)

where you have a form

@using (Html.BeginForm("SomeControllerFunction", "SomeController", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    //various fields for the EF model, plus
     <input type="file" name="ImageFile" id="ImageFile" />
}
