1. 在模型中添加一个属性来存储图像文件：

public class MyModel
{
    public int Id { get; set; }
    public string Name { get; set; }
    public HttpPostedFileBase ImageFile { get; set; }
}

2. 在视图中使用表单和文件上传控件来上传图像：

@using (Html.BeginForm("Upload", "Home", FormMethod.Post, new { enctype = "multipart/form-data" })) {
    @Html.AntiForgeryToken()

    

        
MyModel
        

        @Html.ValidationSummary(true)

        

            @Html.LabelFor(model => model.Name, htmlAttributes: new { @class = "control-label col-md-2" })
            

                @Html.EditorFor(model => model.Name, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.Name, "", new { @class = "text-danger" })
            
        

        

            @Html.LabelFor(model => model.ImageFile, htmlAttributes: new { @class = "control-label col-md-2" })
            

                
            
        

        

            

                
            
        
    
}

3. 在控制器中处理图像上传并将其保存到磁盘：

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Upload(MyModel model)
{
    if (ModelState.IsValid)
    {
        if (model.ImageFile != null && model.ImageFile.ContentLength > 0)
        {
            var fileName = Path.GetFileName(model.ImageFile.FileName);
            var path = Path.Combine(Server.MapPath("~/Images"), fileName);
            model.ImageFile.SaveAs(path);
        }

        // Save your model to the database and redirect to a success page
        // ...

        return RedirectToAction("Index");
    }

    return View(model);
}
