C# 图片上传保存后变黑 - ASP.NET MVC 5

Question

Please bear with me, my English is still improving... Below given code is what I am using to get an uploaded image saved in "UploadedImage" folder in ASP.NET MVC 5 project. But when I use my almost high-end PC having i7 processor, 16GB of RAM, 4GB Graphics Card, all works like a charm. But problem arises when I use my laptop having i3 processor and 8GB of ram or a PC having i3 processor having 4GB RAM.... What I get is only a black image.

public ActionResult Index(FormCollection form)
{ if (string.IsNullOrEmpty(form["image-data"])) return
    View();
var t = form["image-data"].Substring(form["image-data"].LastIndexOf(',') + 1);
byte[] bytes = Convert.FromBase64String(t);
string fileName = form["email"].Replace("@", "at");
fileName = fileName.Replace(fileName[fileName.LastIndexOf(".")].ToString(), "dot");
var fullPath = Path.Combine(Server.MapPath("~/UploadedImage/"), fileName + ".png");

Image image;

using (var streamBitmap = new MemoryStream(bytes))
{
    using (image = Image.FromStream(streamBitmap))
    {
        image.Save(fullPath);
        }
    }

Please help me, I could not get any help from anywhere, thanks in advance

You can try this method to upload file/images

var Upload_Path = "get file path";
string fileExtension = Path.GetExtension(file);
fileExtension = fileExtension.ToLower();
var path = System.IO.Path.Combine(Server.MapPath(Upload_Path),"name.jpg");
Model.ProfileImage.SaveAs(path);

in model you can use

[DisplayName("Picture")]
public HttpPostedFileBase ProfileImage { get; set; }
