【问题描述】：

我试图从httplistener 发送base64 图片，但由于某种原因它没有呈现：

代码：

var gv = ImageToBase64(new Bitmap("bubble.png"), ImageFormat.Png);
revatry.SetHeaders(res, HttpResponseHeader.CacheControl, "cache", RevatryFramework.Mime.PNG);
// ImageToBase64 is stolen from Stack Overflow. It does properly convert as I send the output to the browser

// Extra code here because I tried some stuff to solve issue, but it didn't help; I removed it again, but I kept the variables
byte[] buffer = gv;
res.ContentLength64 = buffer.Length;
System.IO.Stream output = res.OutputStream; // ponse eul zrehgo
output.Write(buffer, 0, buffer.Length);

revatry.EndRequest(res);

我正在使用这个：https://github.com/blockplacer/Revatry 用于网络，但无论我尝试什么，我都无法让图片正常工作。

【解决方案1】：

{
    var bobux = ImageToByte2(new Bitmap("bubble.png"));
    revatry.SetHeaders(res, HttpResponseHeader.CacheControl, "cache", RevatryFramework.Mime.PNG);
    res.ContentEncoding = Encoding.UTF8;

    // Console.WriteLine(bobux);
    byte[] buffer = bobux;

    res.ContentLength64 = buffer.Length; // ponse
    System.IO.Stream output = res.OutputStream; // ponse
    output.Write(buffer, 0, buffer.Length);
    // revatry.Send(, res);

    revatry.EndRequest(res);

我通过使用它解决了它。我直接使用byte发送了二进制数据。
