Question

我是WCF技术的新手，我从我的silverlight应用程序调用此WCF。

现在，我在WCF中定义了一个函数，该函数调用安装在同一台PC上的数据库上的SP。

此SP需要1分钟的时间来执行，并返回包含50列的82000行。

我已在我的应用程序中将wcf超时间隔设置为20分钟。

现在，当我从我的silverlight应用程序调用此WCF函数时，它会在20分钟后给出超时错误。由于SP需要1分钟才能执行，我想知道为什么会出现超时问题？

导致超时的原因是什么？我该怎么做才能避免这种情况？我无法一次性实现分页或任何我需要的所有数据。

请帮帮我们。我附上了我的web.config文件供您参考。

这可能比那简单。您是否关闭或处置您的服务？如果没有，则很可能您的服务连接仍处于打开状态。一旦达到超时限制就会出错。从中获取数据后，明确关闭服务。
