如何在Dotnet中上传图片？

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

[HttpPost]
public ActionResult UploadImage(HttpPostedFileBase imageFile)
{
    if (imageFile != null && imageFile.ContentLength > 0)
    {
        // 获取上传文件的文件名
        string fileName = Path.GetFileName(imageFile.FileName);
        // 指定上传文件的保存路径
        string filePath = Path.Combine(Server.MapPath("~/Uploads"), fileName);
        // 保存上传文件到指定路径
        imageFile.SaveAs(filePath);
        // 返回上传成功的消息或其他处理逻辑
        return Content("Image uploaded successfully!");
    }
    else
    {
        // 返回上传失败的消息或其他处理逻辑
        return Content("Image upload failed!");
    }
}

string uploadPath = Server.MapPath("~/Uploads");
if (!Directory.Exists(uploadPath))
{
    Directory.CreateDirectory(uploadPath);
}
