Linq to sql 可通过存储过程进行查询

这是我的存储过程，它返回一个结果集。现在我必须在Linq中使用这个存储过程来应用一些

WHERE

条件来搜索firstname、lastname等

如何在具有其他where子句的linq中使用此存储过程？

如果使用sqlmetal生成linq2sql实体，请使用/sprocs选项重新运行它以包含存储过程。然后，在datacontext上应该有一个名为SP_GET_RESEARCH_SITES的函数，该函数将调用存储过程并返回entityset

不幸的是，在Visual Studio中生成linq2sql时，我不知道如何设置此选项，但我确信该选项在某个地方：）

存储过程是一种生成代码，可能会将表作为其结果集提供，但是您不能在其末尾添加where子句。如果将存储过程更改为表值函数，则可以将其视为一个表，添加任何where、sort、top和skip都会在函数调用的末尾附加SQL，从而使SQL server进行筛选并更高效地执行
