for example this is the c# backend code:

[Authorize(Roles = "admin")]

    [ActionName("UploadBase64")]
    public OperationResult UploadBase64(base64 im) {
        try
        {
            var dirPath = Path.Combine(
                HttpContext.Current.Server.MapPath("~/uploads/images/"),
                im.imageFolder);
            if (!Directory.Exists(dirPath)) {
                Directory.CreateDirectory(dirPath);
            }

            var path = Path.Combine(dirPath, im.fileName);
            int count = 0;
            Random rand = new Random(10000);
            while (File.Exists(path) && count<1000) {
                count++;
                var names = im.fileName.Split('.');
                if (names.Count() > 1)
                {
                    im.fileName = names[0] + rand.Next() + '.'+ names[1];
                }
                else {
                    im.fileName = names[0] + rand.Next();
                }
                path = Path.Combine(dirPath, im.fileName);
            }
            File.WriteAllBytes(path, Convert.FromBase64String(im.Image));
            OperationResult result = new OperationResult();
            result.succeeded = true;
            result.message = "uploads/images/" + im.imageFolder + '/' + im.fileName;
            return result;
        }
        catch(Exception ex) {
            OperationResult result = new OperationResult();
            result.succeeded = false;
            result.message = ex.ToString();
            return result;
        }
    }

and this is the the front service

const binaryString = readerEvt.target.result;
this.imageService.Uploadbase64(btoa(binaryString), this.fileName, this.imageFolder, this.url).subscribe(
  result => {
    if (result.succeeded) {
      this.imagePath = baseServer + '/' + result.message;
      this.imagePathChange.emit(this.imagePath);
    } else {
      this.toaster.error('خطایی در ذخیره سازی تصویر به وجود  آمده است');
    }
  },
  err => this.toaster.error(' خطای اتصال به سرور'));

Do you have any plan for image upload? #5
