仅当服务返回FaultException< T>时，QuotaExceededException.其中T是一个相当大的对象 [英] QuotaExceededException only when service returns a FaultException<T> where T is a rather big object

问题描述

当服务通过FaultException< T>返回对象时，我收到QuotaExceededException.如果WCF操作的结果直接返回了同一对象，则一切工作正常.有任何想法吗?

I receive a QuotaExceededException when the service returns an object via FaultException<T>. If the same object is returned directly as the result of the WCF Operation, then everything works perfectly. Any Idea ?

这是堆栈跟踪:

----例外----
[QuotaExceededException]缓冲XML内容所需的大小超出了缓冲区配额.

---- Exception ----
[QuotaExceededException] The size necessary to buffer the XML content exceeded the buffer quota.

推荐答案

肯定存在正常和错误返回的对象的大小差异(在您的情况下) T).因此，请增加readerQuotas的大小，以下标记显示默认值.请增加maxStringContentLenght和 maxArrayLength.

Defintely there must be size difference of the object which is returned by normal and through fault (in your case T). So Kindly increase the size of readerQuotas, the below tags shows the default values., Kindly increase the maxStringContentLenght and maxArrayLength.

< readerQuotas               maxDepth = " ; 32;  
            maxStringContentLength = " ; 8192"  
            maxArrayLength = " ; 16384"  
            maxBytesPerRead = " ; 4096"  
            maxNameTableCharCount = " ; 16384"

<readerQuotas              maxDepth="32" 
            maxStringContentLength="8192" 
            maxArrayLength="16384" 
            maxBytesPerRead="4096" 
            maxNameTableCharCount="16384"/>
