如何将字节数组转换为图像？

Question

我尝试将byte数组转换为图像，但没有任何错误。

byte[] data = user.Properties["thumbnailPhoto"].Value as byte[];
if (data != null)
{
    using (MemoryStream s = new MemoryStream(data))
    {
          Bitmap bmp = new Bitmap(s);
          imbThumbnail.ImageUrl = bmp.ToString();
    }
}

Answer 1

您不需要Bitmap课程。您只需要base64编码数据，如下所示

imbThumbnail.ImageUrl = "data:image/jpeg;base64,"+ Convert.ToBase64String(data);

Answer 2

试试这个。

public Image byteArrayToImage(byte[] byteArrayIn)
{
     MemoryStream ms = new MemoryStream(byteArrayIn);
     Image returnImage = Image.FromStream(ms);
     return returnImage;
}

Answer 3

试试这段代码：

var stream = new MemoryStream(bytes);
var image = Image.FromStream(stream);
