为什么写入响应流当内容被损坏

Question

我想写出响应流 - 但它失败，它以某种方式破坏数据...

我希望能够编写存储别处的HttpWebResponse，所以我不能用“WriteFile的”这个流，再加上我想了好MIME类型做到这一点，但它不能为所有的人 - MP3， PDF等...

 public void ProcessRequest(HttpContext context)
    {
        var httpResponse = context.Response;
        httpResponse.Clear();
        httpResponse.BufferOutput = true;
        httpResponse.StatusCode = 200;

        using (var reader = new FileStream(Path.Combine(context.Request.PhysicalApplicationPath, "Data\\test.pdf"), FileMode.Open, FileAccess.Read, FileShare.Read))
        {
            var buffer = new byte[reader.Length];
            reader.Read(buffer, 0, buffer.Length);

            httpResponse.ContentType = "application/pdf";
            httpResponse.Write(Encoding.Default.GetChars(buffer, 0, buffer.Length), 0, buffer.Length);
            httpResponse.End();
        }
    }

预先干杯

由于你写的字，而不是字节。一个角色绝对不是一个字节;它必须被编码，这是你的“腐败”成为像这样做，而不是：

using (var reader = new FileStream(Path.Combine(context.Request.PhysicalApplicationPath, "Data\\test.pdf"), FileMode.Open, FileAccess.Read, FileShare.Read))
{
    var buffer = new byte[reader.Length];
    reader.Read(buffer, 0, buffer.Length);

    httpResponse.ContentType = "application/pdf";
    httpResponse.BinaryWrite(buffer);
    httpResponse.End();
}
