WCF通信问题

本文关键字：问题 通信 WCF | 更新日期: 2023-09-27 18:05:06

在我的WCF应用程序中，我收到base64String格式的图像以及其他一些图像。为了测试我的应用程序，我创建了一个小的.aspx页面，它将发送名字，姓氏和base64string(图像:大小10Kb)到WCF服务。我得到了错误格式化程序在试图反序列化消息时抛出异常:对操作"SaveData"的请求消息体进行反序列化时出错。读取XML数据时已超过最大字符串内容长度配额(8192)。的MaxStringContentLength属性可以增加此配额创建XML阅读器时使用的xmldictionaryreaderquota对象。1号线，位置15301。"

如果我发送没有base64string(图像)的字符串，我能够调试wcf服务代码。但如果我添加base64String我得到这个错误。我增加了所有绑定值("maxReceivedMessageSize")和其他值到最大值。我还是会得到这个错误。这是我的网。配置客户端和服务。谢谢，我真的很感谢你的帮助。

将这些行添加到web中的Binding标记中。配置文件

<binaryMessageEncoding maxReadPoolSize="2147483647" maxWritePoolSize="2147483647">
<readerQuotas maxArrayLength="2147483647" maxStringContentLength="2147483647"   maxBytesPerRead="2147483647" />
</binaryMessageEncoding>
<httpTransport  decompressionEnabled="True" maxBufferSize="2147483647" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647"/>
