Question

在我的WCF应用程序中，我收到了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页面将名字，姓氏和base64string（image：size 10Kb）发送到WCF服务。我收到了错误 “格式化程序在尝试反序列化消息时抛出异常：反序列化操作“SaveData”的请求消息体时出错。读取XML数据时已超出最大字符串内容长度配额（8192）。可以通过更改上的MaxStringContentLength属性来增加此配额创建XML阅读器时使用的XmlDictionaryReaderQuotas对象。第1行，第15301号位置。“

如果我发送没有base64string（image）的字符串，我就能调试wcf服务代码。但是，如果我添加base64String，我收到此错误。我已将所有绑定值（“maxReceivedMessageSize”）和其他值增加到最大值。我仍然得到这个错误。这是我的客户端和服务的web.config。谢谢，我真的很感谢你的帮助。

在web.config文件

中的Binding标记内添加这些行

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

MSDN : binaryMessageEncoding
