Question

我启用了wcf basicHttpBinding，并将TransferMode设置为“Streaming”。
问题是每次我从客户端的流中执行读操作时，我都读取了1536字节，这是一个以太网帧。
如何让我的wcf服务一次发送更大的数据包？

修改

所以，显然默认的BytesPerRead是4096，但是我在客户端和服务器上都改变了这个值。这是配置文件

此外，我发现了一个处理同一问题的未答复的帖子 WCF maxBytesPerRead limit to 4096

服务器服务器

（请注意，我有两个端点，一个用于下载basicHttpBinding中的内容，一个用于使用ws2007HttpBinding进行通信，我指的是我的问题中的basicHttpBinding端点）

看一下这个主题：http://social.msdn.microsoft.com/forums/en-US/wcf/thread/e1f7b040-39a8-4ca8-9def-96b2b47c0d6f/

我认为有几种选择非常适合您的问题。

谢谢，

您可以尝试更改maxBytesPerRead属性：

<bindings>
    <basicHttpBinding>
        <binding name="Streamed" TransferMode="Streamed" TextEncoding="Mtom"
            maxMessageReceivedSize="4000000">
            <readerQuotas mexBytesPerRead="8192" />
        </binding>
    </basicHttpBinding>
</bindings>

Wcf非常小的数据包大小
