尝试调用Web服务时出现通道超时错误
[英]Channel time out error when trying to invoke a webservice
问题描述
调用时出现此错误
请求通道在00：00：59.9970702之后等待答复时超时。 增加传递给请求的调用的超时值，或者增加绑定上的SendTimeout值。 分配给该操作的时间可能是较长超时的一部分。
我已经在SO WCF中看到了这一点，它在大约10次左右的调用后停止响应（节流）
但是我不知道该在哪里实现。无论是在我的webconfig文件还是webservice配置文件中。有什么建议吗？

这通常归结为会话和节流
在.NET 4之前，默认的最大并发会话数为10。这意味着第11个并发会话等待另一个并发会话消失，并最终导致客户端发送超时（默认为1分钟）。
在.NET 4之后，默认值为100 x处理器（核心）数，因此被命中的可能性大大降低
您有3种选择：
- 增加会话限制http://www.codegain.com/articles/wcf/security/wcf-service-throttling-behavior.aspx
- 更快地关闭现有会话（确保您立即在代理上调用“关闭”）
- 增加客户端的发送超时

一般建议，因为很难确定哪个服务导致了您的错误：
确保您的超时值在服务和客户端的配置中匹配。
对于刚接触Web服务的人们来说，这是一个非常普遍的问题。 如果增加一个值，通常最好增加另一端的匹配值。
因此，请确保所有绑定行为的服务和客户端上的所有超时值都匹配，然后再进行尝试。
如果这不起作用，请尝试通过添加零并尝试一下来增加所有值。 如果可行，则开始减少超时，直到找到导致问题的原因，然后对其进行调整。
解决这个问题还有很长的路要走，但是由于您不知道哪个服务引起了问题，这可能是您最好的选择。

可能是您在致电服务后尚未关闭对象。
例：
WCFServices.Module1 objWCFServ =新的WCFServices.Module1（）; 数据集ds = obj.MethodName（param1，param2）; .....
objWCFServ.Close（）; objWCFServ = null;
