Question

我不能从数据库中检索图像

byte[] image = (byte[])(reader["Can_Pic"]); 
if (image == null) 
{ 
    Picture.Image = null; 
} 
else 
{ 
    Memory Stream stream = new Memory Stream(image); 
    Picture.Image = System.Drawing.Image.From Stream(stream);

您的代码应该是这样的:-)

Byte[] image=(Byte[])(reader["Can_Pic"]); 

    if (image.Length == 0) 
    { 
     Picture.Image = null; 
    } 
    else 
    { 
     MemoryStream stream = new MemoryStream(); 
     stream.Write(image, 0, image.Length); 
     Picture.Image = new Bitmap(stream); 
    }
