使用LINQ to SQL确定主键 [英] Determine primary key using LINQ to SQL

问题描述

我正在编写一个基于LINQ to SQL的存储库，我想在其中允许带有int参数的GetByID.签名是:

I'm writing a LINQ to SQL based repository where I want to allow a GetByID with an int parameter. The signature is:

public T GetByID(int id)
{
     // Return
     return _dataContext.GetTable<T>() ....;
}

我的表的主键名称不同.我想做的是为每个T动态确定主键是什么，并向其查询整数= id的值.有什么想法可以最好地实现这一目标吗?

My tables have different names for the primary key. What I'd like to do is determine dynamically for each T what the primary key is and query it for a value of integer = id. Any ideas how to best pull this off?
