使用JQuery的图像实现 [英] Image implementation in using JQuery

问题描述

通过WCF，我可以获取1个图像对象(字节流)，但是之后如何在客户端(JQuery)中将其转换为图像以在屏幕上显示图像.以下是我的代码-

Through WCF I am able to get 1 image object(stream of bytes) but after that how can I convert it into image in client side(JQuery) to show the image on screen. Following is my code -

public Image GetEmployeePhoto(string EmpID)
        {
            string strbase64String = string.Empty;
            try
            {
                if (EmpID != String.Empty)
                {
                    TravelService.ImageService1.FileManager obj = new TravelService.ImageService1.FileManager();
                    strbase64String = obj.retrievefile(EmpID).ToString();
                }

                if (strbase64String != string.Empty)
                {

                    System.Drawing.Image empImage = ConvertBase64StringToImage(strbase64String);

                    return empImage;
                //    System.Windows.Media.ImageSource imageSource = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(hBitmap, IntPtr.Zero, System.Windows.Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions());
                //    imgEmpPhoto.Source = imageSource;
                }
            }
            catch (Exception ex)
            {
                //ShowErrorMessage("Employee Photo");
            }
            return null;
        }

        public System.Drawing.Image ConvertBase64StringToImage(string objbase64String)
        {
            try
            {
                byte[] imageBytes = Convert.FromBase64String(objbase64String);
                System.IO.MemoryStream ms = new System.IO.MemoryStream(imageBytes, 0, imageBytes.Length);

                ms.Write(imageBytes, 0, imageBytes.Length);
                System.Drawing.Image objImage = System.Drawing.Image.FromStream(ms, true);
                return objImage;
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }
