DBLinq查询超时报异常
项目中使用的是DBLinq，查询大量数据时出现异常，如下：
Error Message:Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

这网上能找到SQL出现超时异常处理方法，但是不知道使用DBLinq怎样处理？
[解决办法]
超时了
把SqlCommand.TimeOut设大点，默认是30秒，你设成30000
[解决办法]
诸如分页之类的查询，可使用 .SKIP() .TAKE() 方法 ，一次只返回一定量的数据
