将图像的字节数组从MemoryStream分配给图像 [英] Assigning Byte Array of Image from MemoryStream to Image

问题描述

你好

我正在获取图像的字节数组，我正在使用MemoryStream

I am getting the Bytearray of Image, I am Using the MemoryStream

，然后将Memorystream分配给Bitmap对象StreamSource.然后分配

and Assigning the Memorystream to Bitmap object StreamSource  and after that assigning

ImageSource的位图对象我没有收到任何错误，但也看不到图像

Bitmap object to ImageSource I am not getting any error but also not able to see Image

下面是我的代码.

 使用(var stream = new MemoryStream(userPhto1.photo.ToArray()))
                             {
] stream.Seek(0，SeekOrigin.Begin);
                   var bitmap = new BitmapImage();
                    bitmap.BeginInit();
                    bitmap.CacheOption = BitmapCacheOption.OnLoad;
                    bitmap.DecodePixelWidth = 200;
                    bitmap.StreamSource =流;
                    stream.Close();
                    bitmap.EndInit();
                photoUser.Source =位图;   //PhotoUser的类型为图像
]  
                }

  using (var stream = new MemoryStream(userPhto1.photo.ToArray()))
                {
                  stream.Seek(0, SeekOrigin.Begin);
                   var bitmap = new BitmapImage();
                    bitmap.BeginInit();
                    bitmap.CacheOption = BitmapCacheOption.OnLoad;
                    bitmap.DecodePixelWidth = 200;
                    bitmap.StreamSource = stream;
                    stream.Close();
                    bitmap.EndInit();
                   photoUser.Source = bitmap;   // PhotoUser Is of Type Image
                   
                  }

有人能帮助我吗?
