如何将图像转换到字符流 [英] How to convert an image in to a stream of characters

问题描述

我发现，图像可以存储为一些字符串。要举一个例子，我已经包括了微软Word一部分已经在image.I保存一个Word文件，图像，并将其保存为XML格式。当我打开我得到了下面的一个记事本的XML文件部分。它必须是图像存储为文本的某些流。 有没有一种类似的方式来做到这一点在.NET。

I have found that an image can be stored as some string .To give an example I have included a ms word part that has an image.I saved a word file with image and saved it as xml format .when i opened the xml file in a notepad i got following section .It must be the image being stored as some stream of text. Is there a similar way to do it in .net.

<pkg:part pkg:name="/word/media/image1.png" pkg:contentType="image/png" pkg:compression="store">
    <pkg:binaryData>

我曾尝试以下方法

I have tried following way

 Bitmap bmp = new Bitmap(@"D:/bmp.bmp");
    MemoryStream mem = new MemoryStream();
    byte[] b = mem.ToArray();

但它给我一个字节数组，而不是characters.If是人物，我可以在许多方面使用如保存在XML格式，使用SQL INSERT在一个blob的VARCHAR INSEAD插入图像。等等。

But it give me a byte array instead of characters.If it was characters ,I could use it in many ways such as saving in xml format , using sql insert to insert image in a varchar insead of a blob. etc.
