强制打开DataContext的连接(LINQ) [英] Force the Opening of the DataContext's Connection (LINQ)
问题描述
当您创建数据文件时,它的连接会关闭,直到您检索对象,并且在您使用延迟运算符或后期绑定时检索对象时,它仍然保持打开状态。
When you create a datacontext, its connection is closed until you retrieve objects and it stays open when you retrieve objects in case you use deferred operators or late binding.
是否可能(在不是数据报文的扩展方法中)强制数据报文打开其连接,而无需使用LINQ查询LINQ或使用ExecuteQuery,ExecuteCommand等对数据库进行伪查询?
Is it possible (in an extension method of the datacontext of not) to force the datacontext to open its Connection without querying LINQ with LINQ or doing a fake query to the database with ExecuteQuery, ExecuteCommand, etc?
感谢
推荐答案
您可以使用 DataContext.Connection
连接,然后 Open()
。
You can use the DataContext.Connection
property to retrieve the connection, and call Open()
yourself.
