我设计了WCF服务,其操作合同可以将数据存储在SQL Server数据库中。操作契约采用dataID,dataDescrip。,dataType和(byte array)数据内容等参数。字节数组最初是一个必须存储在数据库中的文件。
我在Web表单客户端应用程序(引用WCF服务)中使用WCF服务来发送数据,但是当我将文件> 40 kb作为带有其他参数的字节数组发送时,它返回错误的请求400错误。当我发送小于30KB左右的文件时,数据成功存储在DB中,不会返回错误。
我认为这与大数据流有关,并且在web.config中将大小更改为更大的数字。我试图改变客户端应用程序Web配置中的大小,但没有运气。还将编码标记更改为返回不匹配客户端和服务绑定的MTOM。我正在使用wsHttpBinding。
不确定问题是什么。 我看过:http://msdn.microsoft.com/en-us/library/ms733742.aspx 但是如何在保存数据到数据库的同时更改当前的wcf服务?
我的服务器配置文件,来自服务库的App.config是:

<compilation debug="true" />
</system.web>
<!-- When deploying the service library project, the content of the config file must be added to the host's
app.config file. System.Configuration does not support config files for libraries. -->
