查看：105
本文介绍了如何在WCF中实现MTOM的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有一个wcf服务，该服务可以返回字节值.当我转换大文件时，响应wcf服务的响应被延迟了.

我选择了MTOM编码来克服这种延迟响应.这里是我的代码和网络配置供您参考

请让我如何在我的应用程序中应用此MTOM技术




Web配置
=============

I Have a wcf service which can return byte values.when i am converting large files, It ''s getting delayed in response of wcf service.

I had choosen MTOM encoding for overcoming this delay response.Here my code and web config for your reference

please let me how to apply this MTOM technique in my application
