从数据库返回和图像 [英] Return and image from database

问题描述

我知道这是一个老问题，我看了很多与我一样的解决方案，但从未和我合作过

系统超出范围！即使我试着用索引来打电话



我尝试过：



if（dReader.HasRows）

{



byte [] previewBytes =（byte []）dReader [Img];

if（previewBytes！= null）

{

context.Response.BinaryWrite（previewBytes）;

}

}

i know its an old question and i looked around many solution same as mine but never worked with me
system out of range ! even i try to call it by index

What I have tried:

if (dReader.HasRows)
{

byte[] previewBytes = (byte[])dReader["Img"];
if (previewBytes != null)
{
context.Response.BinaryWrite(previewBytes);
}
}
