如何在Mvc Asp.Net中创建一个可选择的图像？

<form method="post" enctype="multipart/form-data">
    <input type="file" name="imageFile" />
    <input type="submit" value="上传" />
</form>

[HttpPost]
public ActionResult UploadImage(HttpPostedFileBase imageFile)
{
    if (imageFile != null && imageFile.ContentLength > 0)
    {
        string fileName = Path.GetFileName(imageFile.FileName);
        string filePath = Path.Combine(Server.MapPath("~/Images/"), fileName);
        imageFile.SaveAs(filePath);
    }
    return RedirectToAction("Index");
}

<img src="@Url.Content("~/Images/your_image.jpg")" alt="图像" />
