底层连接已关闭：连接意外关闭 - wcf

Question

我在我的WPF项目中使用WCF服务。 我有大量的数据，大约有847000条记录在表中。此异常扔在客户端

proxy.ServicesClient client = new proxy.ServicesClient(); 
var result = client.GetCustomers(); // here throws ('**ComunicationException was unhandled by user code**: *The underlying connection was closed: The connection was closed unexpectedly*.') 

在我的app.config

<?xml version="1.0" encoding="utf-8" ?> 
<configuration> 
    <system.serviceModel> 
     <bindings> 
     <basicHttpBinding> 
      <binding name="BasicHttpBinding_IServices" closeTimeout="00:10:00" 
       openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" 
       maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"> 
      <security mode="None" /> 
      </binding> 
     </basicHttpBinding> 
     </bindings> 
     <client> 
      <endpoint address="http://localhost:5302/WpfStoreService.svc" 
       binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IServices" 
       contract="proxy.IServices" name="BasicHttpBinding_IServices" /> 
     </client> 
    </system.serviceModel> 
</configuration> 

在Web.Config中

<?xml version="1.0"?> 
<configuration> 

    <connectionStrings> 
    <add name="AdventureWorksLTConnectionString" connectionString="Data Source=.;Initial Catalog=AdventureWorksLT;Integrated Security=True" /> 
    </connectionStrings>

你对WCF服务这个问题？

除非您已将其重写到其他位置，否则默认的数据库连接超时将成为问题。

我认为它可以被禁用，如果您将连接超时值设置为0，但这取决于DbConnection实施;

尝试将此添加到您的连接字符串。 Connect Timeout=0

"Data Source=.;Initial Catalog=AdventureWorksLT;Integrated Security=True;Connect Timeout=0"
