WCF錯誤「可以在一個對象圖被序列或反串行化的項目的最大數目是‘65536’」

我在WCF呼叫接收以下錯誤：WCF錯誤「可以在一個對象圖被序列或反串行化的項目的最大數目是‘65536’」

項目的最大數量可以被序列化或在對象圖反序列化是「65536」

我讀過一噸的論壇帖子，其中許多人提修改的app.config和web.config中指定新的行爲，以便更大的對象圖。我已經做了，這是我在這些文件：

App.Config中的WPF項目：

的web.config

但是，這並沒有幫助。請注意，APP.CONFIG中引用的服務不是我遇到問題的服務。

我也試過如下：

加入這些屬性的服務實現：[DataContract（IsReference =真）]，[ServiceBehavior（AddressFilterMode = AddressFilterMode.Any，MaxItemsInObjectGraph = 2147483646）]

寫了一個自定義的DataContractSerializerOperationBehavior類，它設置了MaximumObjectsInGraph和IsReference行爲。還添加了自定義屬性以應用此服務實現。爲了混亂，我沒有發佈代碼，但可以添加它，如果有人認爲這將是有益的。

想法？想法？我從哪裏出發？

在此先感謝！

我剛剛意識到你的WPF配置文件不正確。所以，我刪除了我的所有評論，因爲他們假設有效的WCF配置。你的WPF配置文件是不正確的......它需要說「客戶端」而不是服務......你在Visual Studio中使用「添加服務引用」嗎？如果是這樣，它應該爲您創建正確的配置文件。

否則，請參閱MSDN瞭解您的WPF項目中客戶端配置文件的正確格式。

我在config文件中添加了更多來自system.service的模型節 – Scot

aha！...我想你可能會發生什麼...我會檢查添加「客戶端」部分。僅供參考 - 這是我從另一個團隊繼承的項目，我不知道他們使用哪種方法爲WPF應用程序生成app.config文件。 – Scot

請嘗試在visual studio中添加一個「Service Reference」，並且在添加服務引用之前不要忘記刪除app.config中的整個「system.servicemodel」部分...您的生活將會變得更加簡單...然後你可以通過添加'maxItemsInObjectGraph'的東西來定製你的配置文件...祝你好運。 – Nabheet

您是否嘗試過提高緩衝區和最大接收郵件大小？

maxBufferSize="6553600" maxBufferPoolSize="52428800" maxReceivedMessageSize="6553600"

這是否將在服務主機項目的web.config？或客戶端的app.config？或兩者？ – Scot

在應用程序的app.config上。 – Josh

這對我來說是未知領域... :-)這是正確的方法嗎？ <結合maxBufferPoolSize = 「2147483646」 MAXBUFFERSIZE = 「2147483646」 maxReceivedMessageSize = 「2147483646」/> – Scot

配置下面的值爲我解決了這個問題。

客戶端配置：

嗨，我嘗試使用你的代碼（綁定和行爲，但我得到這個錯誤信息： **內容類型text/xml; charset = UTF-8不支持服務**。你有任何線索爲什麼我得到這個錯誤信息？ – NoOne

你是返回一個泛型列表或具有尺寸超過65536在查詢一個數組，使用選擇頂部60000或不添加超過60k元素將解決您的問題。

請注意「dataContractSerializer」元素。在我的情況下，我得到的錯誤提到，直到我把這個元素作爲父元素「行爲」的第一項。至少在客戶端確實如此。

WCF錯誤「可以在一個對象圖被序列或反串行化的項目的最大數目是‘65536’」
