在另一个问题中,当通过GetResponseStream()从HttpWebResponse读取时,人们得到的数据不完整.

从嵌入式设备读取数据时我也遇到了这个问题,该设备应该向我发送1000个输入的配置,所有32个字节的头部和64个字节*1000都会产生64032个字节的数据.

直接读取响应流只能为我提供前61个半输入的数据,从那里只有零.

版本a)不工作:

int headerSize = 32;
int inputSize = 64;
byte[] buffer = new byte[(inputSize*1000) + headerSize];

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

using (Stream stream = response.GetResponseStream())
{
    if (stream != null)
    {
        stream.Seek(0, SeekOrigin.Begin);
        stream.Read(buffer, 0, buffer.Length);
    }
}

response.Close();
return buffer;

为了使问题可视化,我单独为每个输入配置打印了64个字节.它基本上由40个ascii字符和几个字节组成,表示布尔值和整数值.

版本A)输出:

当我将ResponseStream复制到一个新的MemoryStream时,我可以完全读取所有1000个输入而没有任何损坏的字节.

版本B)完美工作:
