【问题描述】：
通过使用 WCF post 方法，我将数据存储在数据库中，然后我希望使用 WCF GET 将存储的数据显示在网格控件中。在这里，我编写了代码以使用 POST 方法将数据存储在数据库中。这是工作。将存储的数据绑定到网格控件时出现错误。
我得到以下错误：
在 ServiceModel 客户端配置部分中找不到引用合同“ServiceReference1.IService2”的默认端点元素。这可能是因为找不到您的应用程序的配置文件，或者因为在客户端元素中找不到与此协定匹配的端点元素。
//service.cs

}

请不要在此处发布您的整个程序。隔离不起作用的代码。这个问题，它的发布方式，属于“为什么这个代码不起作用”。不要指望有人会在你留下的占位符中编码和发布代码
