带有泛型表的LINQ查询 [英] LINQ query with a generic table

问题描述

我试着在我的方法中只有一个选择。该方法将选择一个基于定义字符串的表并执行select。

I'm tryng to have only one select in my method. That method will select a table based in a defined string and execute a select.

private static void Load()
{
    DataClassesDataContext contexto = new DataClassesDataContext();
    IQueryable newTable = null;

    string tabela = "A";

    switch (tabela)
    {

        case "A":
            newTable = contexto.GetTable<Table2>();
            break;
        case "B":
            newTable = contexto.GetTable<Table1>();
            break;
        default:
            break;
    }

    var genericQuery = from a in newTable
                       select a;
}

通过正确的表值可以做些什么？

What can I do to have genericQuery with the right table values?

推荐答案

除非泛化Load方法，否则这将不起作用：

This won't work unless you genericize the Load method:

private static void Load<T>()
{
   ...
   var genericQuery = contexto.GetTable<T>();
   ...
}
