.net 使用WCF服务时出现奇怪的异常（可能是字符编码异常？）

我正在调用我以前创建的一个WCF服务，该服务查询语义数据库并返回dbpedia.org链接，这些链接包含实体的名称，例如，您可以找到“http://dbpedia.org/resource/Barack_Obama“或”http://dbpedia.org/resource/Brazil"

我面临的问题是，在调用返回前面提到的URI的方法时，该方法大部分时间都有效，但很少发生此错误：

基础连接已关闭：服务器已关闭预期保持活动状态的连接

我想可能有些资源有不同的编码，比如“http://dbpedia.org/resource/Sergio_Ag也许是“你”这个角色的“你”吧

我尝试在发送回uri之前对其进行编码，但它仍会引发相同的异常

服务配置文件如下所示：

在故障中临时包含异常详细信息，这将允许您获得真正的错误。此外，在服务中重新引用异常之前，您应该记录异常，这样您就可以知道真正的问题是什么，而不必在故障中包含异常详细信息

<serviceDebug includeExceptionDetailInFaults="True"/>

您是否在每次请求后关闭香奈儿？不清楚问题是您在使用特殊字符（“）时总是出现此错误，还是您只是偶尔出现此错误，并猜测可能是特殊字符。服务器端没有发生异常，异常发生在传输中
