C# WCF远程服务器返回意外响应：（413）请求实体太大

我是WCF新手，我正在编写一个WCF服务，该服务具有一个数据协定，该协定将字节数组作为属性。当我转换一个小文件时，它可以工作，但当我使用一个较大的图像时，比如说1兆或更大，我得到

我的客户端代码是

可能的重复我认为您需要为maxBufferSize设置一个更高的值，defaut值为65536字节，这对于1 Mb的ImagemaxBufferSize来说是更小的。不应随意增加maxBufferSize，建议使用流传输模式（在绑定上设置transferMode=“streamed”）。这允许服务器在客户端仍在传输消息时开始处理该消息，而不是等待整个消息被传输，将整个消息放入内存，然后进行处理。我设置transferMode=“Streamed”1的配置的哪一部分。您不能仅仅将transferMode更改为流式传输，运营合同也需要处理流式传输。看见2.maxStringContentLength仅为100000（小于缓冲区大小），因此即使将缓冲区设置为更大的大小，如果消息长度超过1000000，也会遇到问题。
